Accurate determination of the collapse moment of structures by nonlinear analyses is one of
the major challenges for engineers in the seismic design of buildings. Although, structural …

Over the recent decades, with spreading unusual events such as fire, blast, and vehicles
collision, studying the behavior of structures subjected to abnormal loadings has been …

Progressive collapse due to unexpected accidents usually begins with the collapse of one of
the main members of the structures, such as a column or a load-bearing wall. The collapse …

One of the most important issues in buildings is irregularity in the plan or height of the
structure, which causes increasing the seismic damages. In irregularity in height, sudden …

Buildings are always affected by a variety of natural and abnormal forces during their
operation. Impact of vehicle collision is an abnormal load which is not usually considered in …

Buildings may be subject to various external threats throughout their lives. These threats can
cause progressive Collapse to the structure by damaging the critical structural elements …

When the progressive collapse phenomenon occurs due to the column removal, the beam-
to-column connections must have enough resistance and ductility to be able to withstand the …

According to ASCE 7 (2016), Progressive collapse is described as the distribution of an
initial local failure from element to element, resulting finally in the collapse of an entire …
