ƒ^ƒCƒgƒ‹i‰pjF SEISMIC PERFORMANCE EVALUATION OF RC FRAMES IN RAILROAD VIADUCTS USING THREE-DIMENSIONAL NONLINEAR DYNAMIC ANALYSIS
´˜^i‰pjF Focusing on the influence of multi-directional ground motion and of variations in material strength, the seismic performance of RC frames in railroad viaducts is evaluated using three-dimensional nonlinear dynamic analysis. The basis of analysis is a fiber technique. It is demonstrated that, in order to properly estimate seismic behavior, it is essential to use a three-dimensional analysis method that explicitly takes into account the effects of multi-directional motion. It is also reconfirmed that careful attention must be paid to material strength, ad particularly the yield strength of the steel reinforcement. This method of analysis is an efficient and practical application of the latest technical understanding, and by combining the method with engineering judgment, seismic damage analysis becomes possible.
