On 14 August 2018 at 11:35 AM, a relevant portion (about 243 m) of the viaduct over the Polcevera river in Genoa collapsed, killing 43 people. The bridge was designed in the early 1960s by Riccardo Morandi, a well-known Italian engineer, and opened to the public in...
Dr. Ahmed Amir Khalil, PhD, PE, Structural Consultant at Applied Science International, LLC (ASI) will be delivering the Opening Plenary Speech at the Forensic Engineering 8th Congress in Austin, Texas from 8:30AM-10:00AM on Friday November 30th, 2018. His address...
For a limited time only, several Progressive Collapse papers published in Engineering Structures Journal, which discuss the use of Extreme Loading® for Structures (ELS) nonlinear dynamic structural analysis software to analyze structures and design to prevent...
Numerical prediction of progressive collapse of buildings due to extreme loading is still a challenging task. However, increased computational power makes it nowadays possible to analyze not only small-scale connections and mid-size building elements, but also full...
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...
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...
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...
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, wind,...
Ahmed Khalil, Ph.D., P.E., M. ASCE will be presenting a paper entitled, “Nonlinear Dynamic Impact Analysis of Collapsed Debris Using Applied Element Method” at Structures Congress 2018 on Friday, April 20 from 9:30 AM – 10:30 AM in room 202B...
Significant research effort has been devoted in recent years to the evaluation of the capacity of steel frame structures to resist progressive collapse after sudden column loss. Due to the complex load-structure interaction and material behaviour, it can be very...
