Abstract

As a result of terrorist incidents around the world that target important structures, blast loads have received great interest in recent years. The goal of this study is to investigate behavior of different reinforced concrete shear-wall structural systems under blast loading. A finite element model is simulated using SAP2000 v23 and validated with experimental results in literature and showed efficient and accurate results for the behavior of reinforced concrete panels under blast loading. Also, a full 3D model is established using LS DYNA model and its pressure–time data is recorded based on UFC 3-340-02 to compare the results with that of the SAP 2000 model. Blast wave parameters calculator program is created and used in calculating blast loads in the validated and simulated models based on database extracted from UFC 3-340-02. In this research, three reinforced concrete 8-story buildings with different configurations under three different blast waves are simulated with 3D finite element models. The three blast waves considered are of 15m standoff distance and explosive weights of 500 Kg, 1000 Kg and 2000 Kg TNT, respectively. The analyses of buildings are done by applying blast load at each structural element (wall, beam and column) on front face of the building. The load time-history is determined based on the tributary area supported by the element, the actual stand-off distance between the charge location and the joint under consideration (center of structural element), and the angle of incidence between the wave front and the center of each element. The study investigates the global response of shear-wall reinforced concrete structural systems in addition to the response of their individual members under blast loading conditions.
