Jarret Structures produces anti-seismic devices that use fluid viscosity technology to provide both spring and damping functions. Their devices include Fluid Viscous Dampers (FVD), Shock Transmission Units (STU), and Preload Spring Dampers (PSD). FVDs and STUs dissipate seismic energy through the use of silicon fluid flowing through an orifice, with FVDs working in tension and compression and STUs providing a stiff connection during earthquakes. Jarret can customize the size, stroke, and force of their dampers to suit different structural applications.

Analysis of Parabolic Shell by Different Models Using Software SAP 2000ijtsrd
The shell structure consists of a thin reinforced concrete shell without the use of internal columns to create an internal opening., parabolic or spherical cross section. On the other hand, warehouses and playgrounds are conventional concrete frame structures, on the other hand, they can be difficult to design as the exact shape required for the stability of the structure depends on the material used, the dimensions of the enclosure, external or internal loads and other chamfers.. .. Thus, by changing the shell parameter, the performance of the shell will also change. The main goal of this work is to parametrically analyze different designs of cylindrical shells of different lengths in order to analyze two different lengths of taken cylindrical shells, and then change two parameters, first the radius and then the thickness, based on the radii. and the difference in thickness for the same width, length and material of the frame, we will evaluate the behavior of the frame for different models.

Bracing elements in structural system plays a vital role in the seismic behaviour of high rise buildings during earthquake. Many of the structural failures in buildings during strong earthquake shaking have indicated that sustainable strength and stable energy dissipation capability are most desirable to maintain inter story drifts and overall structural displacements within tolerable levels. So earthquake action brings a greater concern in the structural design of buildings which is situated in earthquake prone areas. Steel bracing are the common type which mainly used to resist the lateral loads acting during a seismic activity. Conventional types of lateral load resisting systems are concentrically-braced frames (CBFs) and eccentrically braced frames (EBF). Buckling Restrained Braces (BRB) are recent developed structural system which has a stable energy dissipation property. Main advantage of BRB is its ability to yield both in tension and compression without buckling, thus obtaining a stable hysteresis loop. The BRB brace placed in a concentric frame is termed as BRBF system.

STRUCTURAL RESPONSE CONTROL OF RCC MOMENT RESISTING FRAME USING FLUID VISCOUS...IAEME Publication
Frequent earthquakes round the globe and large no of structures vulnerable to it have
necessitated the need for structural response control to gain pace in application around the
globe. This paper discusses the use and effectiveness of one such device, fluid viscous dampers,
for response control of structures and to reduce damping demand on structural system. In this
paper a non-linear time history analysis has been carried out on a 3D model of a 12 story RCC
MRF building using 3-directional synthetic accelerogram. Two different cases of building
models with and without supplemental damping have been analyzed using ETABS. The story
responses in terms of absolute maximum displacement and story drift have been compared.
Time history response plots for the two models have also been compared for various responses
viz. roof displacement and acceleration, base shear and story shear forces, along with the
various energy components and damping behavior. The results of the time history analysis are
in close conformation with previous investigations and represent the effectiveness of dampers
in improving the structural response as well as damping demand on structural systems
Seismic performance of structure with fixed base, base isolated structure and...eSAT Journals
Abstract Earthquakes can create serious damage to structures. The structures already built are vulnerable to future earthquakes. The damage to structures causes deaths, injuries, economic loss, and loss of functions. Damage to the structure causes due to ground acceleration. This can be minimizing by increasing strength of the structure. Sometimes it is not possible to increase the strength of the structure indefinitely. So it should be tried to increase the capacity of structure using seismic improvement techniques. In this study, there are three different types of G+10 structures with fixed base, structure with viscous damper and structure with high damping rubber bearing are considered. These structures are modeled using finite element software SAP2000v16. These structures have same plan area and are assumed to be situated in seismic zone IV and having medium soil condition. The analysis of these structures is done by performance based pushover analysis method and response spectrum method. The pushover analysis method is used to find out the performance point and capacity of structure. High damping rubber bearing isolators (HDRB) and viscous damper (VD) are use for seismic improvement of RC structure. The procedure of analysis adopted for fixed base structure is same repeated for structure with viscous damper (VD) and base isolated (HDRB) structure. So it will help in comparative parametric study. The results of analysis are compared in terms of storey displacements, modal time period, storey acceleration, performance point, storey drift. The comparative study shows that storey displacement, storey acceleration, storey drift is reduced substantially for structure with high damping rubber bearing (base isolated structure). Key Words: Base isolated structure, Pushover analysis method, Response spectrum method, Viscous damper, High damping rubber bearing, SAP2000v16 etc.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

The graph shows influence of the alpha value on the damping performance.

α = 0.1
α = 0.5
n area
As we can see, an alpha value (0.1) provides a more reactive reaction at low
velocity that increases the dissipated energy.
The second advantage of alpha 0.1 is to limit the maximum reaction when the
velocity grows up, this point is very interesting to limit this maximum into the
structures at high velocity.

4. Performance
The graph shows influence of alpha value on the energy dissipation.
Alpha: 0.1 Alpha: 0.5
The GREEN area represents the energy area dissipated during one cycle with a damper set
with alpha 0.5.
The PINK area represents the difference between energy areas dissipated by a damper set
with alpha 0.5 and 0.1.
As result for 2 dampers at same maximum force, stroke, and velocity if we use alpha 0.1
the energy capacity is more important than if we use a higher alpha value (0.3, 0.5, ...)
THE LAW ALPHA VALUE TECHNOLOGY (alpha 0.1-0.05) ALLOWS TO:
INCREASE THE ENERGY CAPACITY

5. FVD: Fluid Viscous Damper
ASR Series
A Jarret Structures’ damper is designed to dissipate seismic or
dynamic energy on a structure. Douce-Hydro’s/Jarret Structures’
ASR series dampers work in tension and compression. The
dampers can reduce longitudinal and transversal or vertical
displacement of a deck. They can be installed in different type of
structures, for example, longitudinally between the deck and the
abutment, or in transverse between the deck and the pier structure
of a bridge. They can equally be installed in a building for brace or
base isolation. Seismic energy is dissipated into the damper unit
instead of being dissipated in the concrete or steel structure.
Behavior law:
α
F = C .V
Working Principle
A Douce-Hydro’s/Jarret Structures’ viscous fluid damper works on the principle of the rapid
passage of viscous fluid through a narrow orifice or port generates high resistance, which

6. STU: Shock Transmission Units
AB Series
A Shock Transmission Unit (STU), also called Dynamic Connector is
designed to be connected between bridge structure components to
form a rigid link under dynamic loads induced by forces such as vehicle
braking and earthquakes. At the same time, the structure will be able to
move freely under slow applied loads such as thermal expansion and
creep shrinkage.
The unit is connected between elements of bridge structures at
expansion joints, or near the bearings between the superstructure and
the substructure.
The use of STU allows the load sharing of a suddenly applied force.
Working Principle
These dampers work on the principle of rapid passage of viscous fluid through a narrow gap,
orifice or port, generates only minor resistance. A STU should block the deck of a bridge during
a quick motion and behave like a spring with a very high stiffness. At the same time, the Shock
Transmission Unit should deliver a low reaction force during the slow displacements of thermal
expansion or contraction of the deck.
A Special valve is fixed between the 2 chambers

Douce-Hydro’s/Jarret Structures’ AB series is made with a steel reservoir, with a piston rod
sliding through it. On the piston rod, there is a fixed head, which separates the reservoir into
two chambers.
When the unit is filled with silicon fluid, at rest, the pressure is the same in both chambers.
When the velocity goes up, the silicone must pass into a clever valve that generates pressure.

Douce-Hydro’s/Jarret Structures’ AB series are velocity dependant.
Temperature and Aging:
A variation of the outside temperature, which can range from - 55ºC to + 80ºC, does not change the amount
of energy dissipated per cycle. There is no ageing of the silicone fluid.
Douce-Hydro’s/Jarret Structures’ AB series have been tested in very severe environmental conditions,
including fire.

9. PSD: Preload Spring Dampers
PSD Series
Working Principle
The PSD works on the principle of rapid passage of viscous fluid through a narrow
orifice or port generates high resistance, which dissipates a large amount of
energy. In order to avoid the displacement before reaching a certain force level,
Douce-Hydro/Jarret Structures can define a preloaded value, F0. Before reaching
this value it is not possible to compress the unit. After the dynamic compression of
the PSD, the unit has the ability to return to its original position due to the
integrated spring function. For example, this return force value is defined in order
to overcome the friction force of the sliding pot bearings. In order to generate this
damping and spring function in two directions, a double-acting PSD is used.

Application on individual buildings
Working Principle:
BA The base isolation is a solution to protect individual or small buildings. This system is a combination
using isolators (Elastomeric plot) and dampers.
The isolators reduce the force but increase the displacements. The dampers allow reducing the
displacements by dissipating energy.
With this combination, the building structure is protected and the force and displacement transmitted at
the foundation are low.

Regardless of the type construction, Douce-Hydro/Jarret Structures creates

- Transversally on the piers.

Let consider a bridge (4 spans, Length = 300m, Weight = 10000 t) to protect against a longitudinal earthquake
with the following data:
Soil type: EC8-B and PGA = 2m/s².
The deck is supported by 5 identical piers (P1 to P5) with a longitudinal stiffness: Kp = 300MN/m
If we put dampers in some piers, these units will dissipate a big part of
the seismic energy and therefore, reduce the forces in the fix pier

Applications
Shock Transmission Units (STU) can be used for both steel and concrete structures.
They are disposed on cable stayed and suspension bridges in order to eliminate large displacements of the
deck during an earthquake. STU can equally be advised to elevate light rail structures as well as in bridge
parapets to share collision forces through an expansion joint. For other civil engineering structures such as
buildings, STU can provide additional rigidity in the frame structure. STU can also be used to strengthen
adjacent buildings during a seismic event.
The retrofit of existing steel truss railway bridges with STU can allow heavier trains and take the increasing
braking forces without a change to the substructure. STU can be made to strengthen supporting piers which
have been found inadequate due to increase in traction and braking forces, or which have sustained damage
caused by corrosion.

Page 22
23. Dampers for
cables stay
AVE Series
The large global development of the technology for stay cables has created a need for
damping. Initial attempts to adapt commercial dampers failed to meet the specific
requirements of the bridge industry because they were not appropriate for bridges.
Douce-Hydro/Jarret Structures has developed a new generation of dampers in order to satisfy
the special requirement of damping stay cables.
Because long-term vibrations due to wind and rain create fatigue stress in the cables, the idea
is to offer a very reliable unit which is able to smoothly damp vibrations without creating any
additional stress to the structure.
Working Principle
The Douce-Hydro’s/Jarret Structures’ Cable Stay Dampers (CSD) works on the principle that
rapid passage of viscous fluid through a narrow orifice or port, generates high resistance,
which then dissipates a large amount of energy. The energy is dissipated in heat.
In order to avoid any possible leakage, the body of the unit is made of a single stainless steel
part. A piston head is moving through the viscous fluid, and the lamination of the fluid creates
the viscous damping. A special developed seal installed on the top of the body allows for the
long-term microscopic movement of the damper caused by the normal displacement of the
deck.
The behaviour law of the viscous damper is F= C.Vα. According to the specifications required
of a particular application, Douce-Hydro/Jarret Structures can provide a value for the
coefficient alpha which can range from 0.3 to 2. A pure linear damper F=C.V can also be
provided.

24. Preloaded Spring Dampers
A Preloaded Spring Damper (PSD) is a unit designed to dissipate seismic energy on
structures such as bridges. The PSD reduces longitudinal and transversal displacement
of the deck. Douce-Hydro/Jarret Structures can provide two types of PSD: working in
tension/compression, or acting only in compression. Douce-Hydro/Jarret Structures can
install the PSD compression type longitudinally between the deck and the abutment, or
install a PSD tension/compression unit in transversal position between the deck and the
pier structure. The PSD acts as a shear key which has the possibility to regenerate itself
automatically after a dynamic event. The seismic energy is dissipated in the PSD unit
instead of being displaced in a steel or concrete structure. Douce-Hydro/Jarret Structures
can accommodate transversal and longitudinal seismic displacement, and at the same
time take into account longitudinal displacement such as creep shrinkage and thermal
expansion or contraction.

25. Improvement in using
PSD
In the previous solutions, the central pier was fixed.
Using STU or dampers help us to decrease shear in the fix pier but, when this pier is too stiff, their
efficiency will be very weak.
If the shear of the fix pier has to be decreased, we must consider another solution.
The best idea of the new solution is the following:
- If the central pier remains fix during the seismic oscillation of the deck, this pier, during earthquake,
will have to move the deck, it will provide large shear forces in this pier (see drawing below).
In order to solve this problem, an
elegant solution is to install between Pier
Deck
the deck and the pier a PSD.
The PSD had 3 functions:
1 Link the pier to the deck during service. (Preload force)
Before earthquake
2 Damp energy during the earthquake. (Energy dissipation)
During earthquake
3 Align the deck after the earthquake.
After Earthquake
Page 25
26. Improvement in using
PSD
The PSD installed in P3 has to be able to fulfill the following mechanical requirements:
- In service, the deck is submitted to forces such as frictions on sliding pot bearings (2.5% deck weight).
Therefore, for this bridge, the device’s preload must be ≥ 2500 kN.
- This means that under any static horizontal force lower to 2500 kN, the device acts as a fix connection
between the deck and the pier.
During earthquake, as the seismic forces, higher than this preload, the device will act as an elastic link with a
damping effect.
In our example, we have installed a PSD in the central pier and we have let the 4 other piers free.
A time history analysis has been achieved and gave the following result:
Shear force on P3 = 3500 kN for a max device compression of 35 mm
SZ
(FP3 corresponds with the force applied on the central pier and F total is the amount of force applied on all the structure.)
Shear in P3 was divided by approximately 2.2, compared to the best of the other solutions.
In certain cases, the ratio can reach 5.
