Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2008.
Includes bibliographical references (leaf 51).
The primary objective of this thesis is the introduction of the current code, ASCE 7-05 into the base isolation design and the analysis of base isolation response due to seismic forces. An eight story irregular structure is modeled using SAP2000 structural program. The time history of Northridge earthquake is used as a seismic forcing function of the structure. The base isolator is designed by using the principle of bilinear modeling. Therefore, the base isolation system is analyzed using the non-linear time history analysis. The response of the isolation system is analyzed, and especially its hysteresis loop. Results show that the inputted energy of the seismic forces is dissipated by hysteretic and modal damping.
