ASCE North Carolina -High Fidelity Non-Linear Structural Analysis Under Extreme Loading Conditions Using Extreme Loading Technology
Ayman Elfouly, PE from Applied Science International presented to ASCE North Carolina on the topic of High Fidelity Non-Linear Structural Analysis under Extreme Loading Conditions using Extreme Loading Technology Summary: Extreme Loading for Structures Software or...
Seismic Debris Field for Collapsed RC Moment Resisting Frame Buildings
Abstract: The debris field of earthquake-induced building collapse can block or reduce the capacity of adjacent sidewalks and roads, hinder emergency and evacuation operations, and therefore adversely influence the seismic resilience of a community. To consider the...
Progressive Collapse Assessment of Precast Prestressed Reinforced Concrete Beams Using Applied Element Method
Abstract: Due to the repetitive progressive collapse events, it became necessity to form theories of designs against those cases of loadings. Prestressed reinforced concrete elements become widely used in construction field due to various properties that contribute to...
Research & Practice on Progressive Collapse & Robustness of Buildings
Extreme events (i.e. terrorist attacks, vehicle impacts, explosions, etc.) often cause local damage to building structures and pose a serious threat when one or more vertical load-bearing components fail, leading to the progressive collapse of the entire...
Research and Practice on Progressive Collapse and Robustness of Building Structures in the 21st Century
Extreme events (i.e. terrorist attacks, vehicle impacts, explosions, etc.) often cause local damage to building structures and pose a serious threat when one or more vertical load-bearing components fail, leading to the progressive collapse of the entire structure or...
Specifying Safe Demolition
Every day, old structures are demolished to make room for new and improved buildings, bridges, and other structures. More often than we would like, during the course of these demolitions, things do not go as planned and loss or damage to property can occur. The...
Using the Applied Element Method to simulate the dynamic response of full-scale URM houses tested to collapse or near-collapse conditions
In this work, the Applied Element Method (AEM) is employed to reproduce the dynamic response of three full-scale unreinforced masonry (URM) house specimens tested on a shake-table. Two of the test specimens correspond to a calcium-silicate terraced house typology...
The Applied Element Method and the modelling of both in-plane and out-of-plane response of URM walls
TThe Applied Element Method (AEM) is a relatively recent addition to the discrete elements methods family. Initially conceived to model blast events and concrete structures, its use in the modelling of masonry structures subjected to earthquake actions is steadily...
Extreme Loading for Structures – Version 6.0 Released!
We’re happy to announce the release of our Advanced Structural Analysis Software, Extreme Loading for Structures (ELS) Version 6.0! ELS is used by structural engineers and researchers around the world to study the effects of blast, progressive collapse,...
Introducing DriftTrak® Headed Stud PTS
The Steel Network, Inc. (TSN) has just released the newest product in our popular DriftTrak line.The goal of this product is to save labor while increasing design flexibility. Benefits of DriftTrak Headed Stud PTS: Easy Clip to Panel Alignment Drastically Reduce or...
