| Abstract: | In this paper, the characteristics of aseismic structural reliability are analyzed. Emphasis has been laid on the discussion of structural reliability of the bearing capacity against earthquake actions. Based on calibration of the reliability indices of current aseismic code and by use of the method of optimization, partial factors for earthquake action and for structural member resistance in aseismic design expressions as well as coefficients of combination for ith time varying load have been determined. Meanwhile, the load effects of structural member calculated by the new aseismic design code has been compared with those of the current one. |
