Dynamic Analysis of Soft Storey Frame with IsolatorsIJMTST Journal
Soft storey buildings are very common in Indian housing construction and the bottom storey is left open without walls for car parking. Past earthquakes showed that these kinds of buildings performed poor and the damages are also heavy. As the base isolation is a technique developed to prevent or minimize damage to building during an earthquake, this study focuses on the time history analysis of a soft-storey building with and without lead rubber isolator. The soft-storey building with and without isolator is analysed using Elcenrto earthquake data and the dynamic characteristics are compared.
Structural Analysis and Design of Castellated Beam in Fixed ActionAM Publications
The depth is the most important parameter which governs the sectional property of the section. For the serviceability moment of inertia plays very important role and moment of inertia of I-section is directly proportional to the third power of the depth. Research on cellular beams with circular web openings is very limited and is less developed than Cellular beams which may be attributed to the fact that cellular beams are more complicated to analyze due to their continuously changing section properties around the cell.

seismic response of multi storey building equipped with steel bracingINFOGAIN PUBLICATION
Steel bracing has proven to be one of the most effective systems in resisting lateral loads. Although its use to upgrade the lateral load capacity of existing Reinforced Concrete (RC) frames has been the subject of numerous studies, guidelines for its use in newly constructed RC frames still need to be developed. In this paper the study reveals that seismic performance of moment resisting RC frames with different patterns of bracing system. The three different types of bracings were used i.e. X - bracing system, V - bracing system and Inverted V - bracing system. This arrangement helped in reducing the structural response (i.e. displacement, interstorey drift, Shear Forces & Bending Moments) of the designed building structure. An (G+6) storey building was modelled and designed as per the code provisions of IS-1893:2002. And linear analysis is been carried out in the global X direction. The analysis was conducted with a view of accessing the seismic elastic performance of the building structure.
Coupling Beams Design in High-Rise Core-Wall Structures
Shear wall structures are most important lateral-force-resisting-systems that have been shown to be
very efficient in resisting seismic loads. But previous earthquake damages showed that the coupling
beams were easily damaged in the earthquake and it was often used as an energy dissipation part in structures.

Study of Steel Moment Resisting Frame with Reduced Beam SectionIJERA Editor
A research became necessary after the collapse of steel structure during the 1994 Northridge and 1995 Kobe
earthquakes. Reduced beam section emerged as one of the best solution. Guidelines about the cut, that is to be
introduced in the flange of the beam section, are obtained from FEMA 350. Here, a G+15 storey steel building is
modeled using RBS as a component in one building and regular beam section as a component of the other in
STAAD PRO V8i. Time history analysis is carried out in this paper. Displacement, storey drift, time period and
base shear of both the buildings are compared as the result. Base shear shows no change but considerable change
in displacement and storey drift is observed
A Study of Reduced Beam Section Profiles using Finite Element AnalysisIOSR Journals
Abstract: Reduced beam section (RBS) is one of the several connection types, which is economical and
popular for use in new steel moment frame structures in seismic zone. To form RBS connection, some portion of
the beam flanges at a short distance from column face is purposefully trimmed so that the yielding and plastic
hinge occurs within this area of flanges. Use of RBS connection is found advantageous due to: a) the shear
force in the panel zone is reduced; b) the force demand in column continuity plates i.e. stiffeners are reduced;
and c) strong-column – weak-beam requirement is satisfied. Although, radius cut RBS is qualified by
ANSI/AISC, FEMA codes, various flange cut shapes like constant, tapered, radius cut, drilled holes are possible
to reduce the cross sectional area of beam flanges. The purpose of this study is to understand behavior of RBS
beam-to-column moment connections for various flange cut geometries. This document represents nonlinear
finite element analysis of the connection models performed using the computer program, ANSYS/Multiphysics

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
