Water-Driven Debris Impact Forces on Structures: Experimental and Theoretical Program.
Water-driven debris generated during tsunamis and hurricanes can impose substantial impact forces on structures that are often not designed for such loads. This presentation covers the design and results of an experimental and theoretical program to quantify these potential impact forces. Two types of prototypical debris are considered: a wood log and a shipping container.
Full-scale impact tests at Lehigh University were carried out with a wooden utility pole and a shipping container. The tests were carried out in-air, and were designed to provide baseline, full-scale results. A 1:5 scale shipping container model was used for in-water tests in the Oregon State University large wave flume. These tests were used to quantify the effect of the fluid on the impact forces.
Results from both experimental programs are presented and compared with theoretical predictions. The analytical predictions are found to be in sufficient agreement such that they can be used for design. A fundamental takeaway is that the impact forces are dominated by the structural impact, with a secondary affect provided by the fluid.
This powerpoint presentation deals mainly about bearing stress, its concept and its applications.

Development of a Blast and Ballistic Resistant Insulated Wall Panel.
Accidental and intentional detonations of high explosives are an unfortunate reality for not only military facilities, but any building. In the United States, designing for blast loads is required of all military and government structures. Additionally, there has been a recent emphasis on constructing energy efficient, sustainable buildings. Insulated concrete wall panels can meet both requirements due to the blast resistance of reinforced concrete and the thermal properties of the interior insulation layer. This research project focuses on improving the response of an insulated concrete panel to explosions at both larger and small scaled distance, as well as the ballistic resistance of the panel. Emphasis is placed on innovative, emulative reinforcement detailing to improve far scale explosions, while shock resistant materials are utilized within the insulation layer to improve small scale explosions and ballistic response. Static tests are conducted under both point and uniform loading to obtain resistance functions to predict the dynamic response of the insulated panel. Experimental, numerical, and analytical results will be discussed.

LITERATURE WORK STUDY OF PRECAST CONCRETE CONNECTIONS IN SEISMICIAEME Publication
Structures made in Precast concrete is increasing in India. The special interest of developing any connections is to be done using commonly used construction materials, such as cast-in-place concrete. This is an investigation of the seismic response on the precast structures due to the beam to column connection behaviour. Earthquake could damage the whole structure if it is not properly designed, especially in high seismic regions.
P- Delta Effect in Reinforced Concrete Structures of Rigid joint IOSR Journals
Popularity of High-Rise structures of rigid joint frame system are incresing day by day to accommodate growing people in metropoliton city and to construct the structures without any special structural component. However combination of rigid frame with RC structure get 30 storey as maximum storey and prone to collapse under severe displacement, axial force and moment, if the P-Delta effects does not included in analysis and design phase. Due to complexity and low knowledge of P-Delta analyses designers, engineers and architectures are prone to perform Linear Static analysis which may eventually become a cause of catastropic collapse of the high-rise. 12 cases and 2 different analysis are performed to give a light on the P-Delta effect in RC Structures of Rigid Joint which will aware and suggest concering person to understand, make experience and perform P-Delta analysis of the high-rise for safety using numeriacal modelling which may accelerate the process and reduce the complexities.

ANALISI DEL RISCHIO PER LA SICUREZZA NELLE GALLERIE STRADALI.Franco Bontempi
SOMMARIO
Il tema della sicurezza, quando si parla di gallerie stradali, assume ancora più importanza, dato che un banale incidente o un guasto di un veicolo possono degenerare in uno scenario che causa un elevato numero di vittime. Ad esempio, il 24 marzo 1999, 39 persone sono rimaste uccise quando un mezzo pesante che trasportava farina e margarina prese fuoco all’interno del Tunnel del Monte Bianco. Nella prima parte dell’articolo vengono spiegate le fasi logiche che un modello messo a disposizione dalla PIARC/OECD, il Quantitative Risk Assessment Model (QRAM) [1-2], segue nel processo di Assegnazione del Rischio, e come esso ricava i valori dei relativi indicatori. Nella seconda parte dell’articolo, invece, viene mostrata un’applicazione di tale modello su una galleria esistente che si trova nel sud Italia, accompagnata da un’analisi di sensitività sui parametri che influenzano maggiormente il livello di rischio.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Debris SiteAssessment
Point-source debris
Shipping container yards
Ports with barges/ships
Site assessment procedure
Determine potential debris plan area
Number of containers * area of a container
Define debris concentration: area of debris/land area
2% concentration defines debris dispersion zone

Goals of NEES Research Study
Determine the debris impact forces from tsunami
generated debris on structures
Flexible debris
Low velocity, ‘moderate’ mass
Consider fluid effects and (container) contents
Provide relatively simple design formulas
Impact force and duration
Tsunami Loading, Ftotal

Conclusions
Simple formula for design impact forces validated by
experimental data
Assumptions are conservative
Container contents don’t affect impact force
significantly, although duration can be increased
Results indicate fluid doesn’t affect impact force
substantially
Other conservative assumptions compensate for slight
conservatism in ignoring it
Results are the basis for the proposed debris impact
forces in ASCE 7
