초록

The LS DYNA software is employed to simulate the behavior of composite and reinforced concrete shear walls under explosion loading in two directions (parallel and perpendicular to the wall) in this manuscript. The composite wall is specifically engineered to match the RC shear wall, using a corrugated steel sheet within the wall structure. Therefore, the accuracy of the numerical simulations has been verified by comparing them with comparable laboratory models and data. The results of this study are important: they offer a thorough comprehension of the response of these walls to blast loading. Analysis of the horizontal and vertical displacements, von Mises stress, effective plastic strain, and damage to the walls are conducted at various explosion intensities. The behaviors of the two walls are then compared and contrasted. The presence of a corrugated steel sheet within the frame of the composite wall results in reduced horizontal and vertical displacements compared to the RC shear wall. The steel frame elements experience a greater von Mises stress when subjected to force perpendicular to the wall plane in the composite wall. Element damage occurs earlier under vertical loading parallel to the wall plane compared to force perpendicular to the wall plane.
