摘要：

Direct economic earthquake loss (DEEL) estimation and prediction framework was proposed. The basic data of buildings were obtained using GIS. A simplified multi-degree of freedom (SMDOF) calculation model of SSSI was established to calculate the vulnerability curves. Based on GIS, a structure replacement cost calculation method and a structure loss ratio calculation model were proposed for the main structure. Finally, the proposed method was applied to Sichuan University Wangjiang campus. The reinforced concrete (RC) frame structure had lower damage probability than high-rise shear wall structure. The RC structure had the largest total DEEL, DEEL per building and unit area.
