【Abstract】 The ratio of the base shear forces obtained using the direct displacement-based seismic design method to those obtained according to the current seismic code, and the ratio of the base shear forces obtained using the direct displacement reliability-based seismic design method to those obtained according to the current seismic code are formulated. Then, the effect of main factors on the above two ratios is analyzed.更多还原
