Seismic site-response analysis: A case study in Malaysia.

A one-dimensional (1-D) seismic site response analysis were conducted using the nonlinear (NL) methods to assess the peak surface acceleration (PSA) and soil amplification. 10 profiles were selected from Peninsular Malaysia site. Three earthquake time history such as Loma Prieta, Acheh and Ranau were scaled to 0.03g, 0.07g and 0.10g and applied to all sites. The results showed that the calculated PSA and soil amplification factor are higher at soil types C compared to soil types D. Moreover, the NL results showed that deamplification did occur in the soft soils of Peninsular Malaysia. The paper contributes to the seismic site-response studies for soil amplification in Peninsular Malaysia. [ABSTRACT FROM AUTHOR]
