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...
Progressive Collapse Assessment of Precast Reinforced Concrete Beams Using Applied Element Method
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...

Measures for Reducing Vulnerability of Building Structures Due to Explosions
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 damages, thus preventing the progressive or disproportionate collapse.

High Fidelity Numerical Seismic Modeling of Ancient Brick Structures
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 for an efficient computational technique for analyzing such structures and providing reliable results for a large number of buildings within a reasonable time frame.
