Abstract: The effect of vertical baffles as the passive control in liquid storage tanks (LSTs) on the reduction of seismic responses was investigated for bidirectional earthquake excitations. Various baffle configurations were ...

Abstract: The studies on the seismic control of a secondary system (S-system) in the base-isolated primary system under multicomponent earthquake is scanty. In this study, an S-system response mounted on a floor of a three-dimensional ...

Abstract: Base isolation of structures with a friction pendulum system (FPS) has been a topic of great interest for research in the past. The efficiency of the FPS system in isolating a structure depends upon a number of crucial ...

Abstract: Due to the near blast condition, columns on the front face of the building may snap off in the blast load’s initial state, leading to a condition of the blast load and progressive collapse effects occurring simultaneously. ...

Abstract: Severe damage and failure of liquid storage tanks (LSTs) due to earthquakes have been observed. Consequently, various strategies for alleviating the seismic safety of LSTs have evolved, of which energy dissipative devices ...

Abstract: A three-dimensional (3D) model of a six-story building subjected to a surface blast is analyzed using the coupled numerical approach. The simulation incorporates the explosion process, shock wave propagation through air ...

Abstract: A surface explosion imparts both the air pressure and ground acceleration on structures. Very little literature is available on the effect of a surface blast on structures, especially for multistory buildings. In the present ...
