Abstract:

This paper includes the study ofbehavior of a single degree of freedom system withnonlinearviscous damper, semi active variable damper and semi active stiffness damper subjected to harmonic excitation. In this paper, single story asymmetric building is considered. The mathematical model of building subjected to harmonic excitation is obtained and solution of this is obtained by state space method. The building is considered with different dampers.The response of building is obtained under resonance and non-resonance condition and the comparison of response for these different cases is carried out.
