Abstract

Structural
engineers are faced with many different challenges when designing structures,
especially in important reinforced
concrete buildings that could be subjected to blast loads. The response of
structures due to explosions are controlled by some parameters, such as mass
and standoff distance of charge, dimensions and direction of structure,
adjacency to other buildings, and important properties of the land. A common
lateral load resisting system that is particularly vulnerable to blast loads is
the internal reinforced concrete shear wall in urban metro stations. This study
investigated the dynamic behavior of the internal wall in a metro station in
the effect of blast loading. To assess
the progressive collapse of these structures, the damaged walls should be modeled in software. The modeling of damage walls is complicated; therefore,
in this study, after analysis of the area of damage, an equal wall was proposed
to substitute for the damaged wall.
