Seismic Performance Evaluation of Steel Buildings Augmented with Viscous Fluid Dampers

Abstract

Design of earthquake resistant structures requires both ductility and stiffness. Lateral force resisting systems such as moment resisting frames and braced frames are conventional and have unexceptional performance. Structures subjected to earthquake forces are vulnerable to collapse and large lateral displacement. This leads us to focus on limiting this displacement. Energy Dissipating Devices (EDD) provided at appropriate locations in a building are an effective solution in reducing the seismic energy. The mathematical formulation of MDOF systems are solved by using New mark Beta implicit step by step integration method. The entire study is focused on time domain form only. The structural output results are measured in terms of structural displacement, absolute acceleration, storey shear force and base shear. The analytical investigation is being carried out for the blast load parametric prediction. In the present study, the effective blast resistant technique for the protection of structural components could also been suggested.
