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...
Abstract: Progressive collapse is defined as either partial or overall failure of the structure due to losing one of the main structural elements. In order to control this chain reaction, it is important to study the main structural elements behavior under column...
Abstract Explosions bring a serious risk of damage or collapse when are produced inside buildings or in the close proximity. As the hazard intensity and possible effects are difficult to quantify, the structure should have the capacity to survive with inherent...
Abstract: The evaluation of the seismic vulnerability of historical masonry buildings is a difficult task due to the uncertainty regarding structural characteristics and construction techniques, mechanical properties, and pre-existing damage. Hence, there is a need...
ASI’s paper on the progressive collapse of the Polcevera Viaduct Bridge in Genoa, Italy will be available free for the next 50 days from Engineering Structures. ASI Engineers modeled up the bridge and simulated the collapse using its Extreme Loading for...
ASI will be attending the 2019 Structure Congress in Orlando, FL from April 24-27, 2019. ASI sessions this year focus on the Protective Design for Structures and industrial facilities. Below are the Sessions that ASI is participating in. ASI Engineers will also be...
Ahmed Khalil, Ph.D., P.E. will be presenting a paper entitled, ” Nonlinear Dynamic Alternative Load Path Analysis of 10-story Concrete Shear Wall Flat Plate Building”, at Structures Congress 2019, Saturday, April 27th from 8:00 – 9:30 AM in the...
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...
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...
