碩士 === 國立中央大學 === 土木工程學系 === 105 === A complete seismic evaluation method for buildings include preliminary evaluation and detailed evaluation, the study propose preliminary and detailed seismic evaluation method for steel structure buildings. Preliminary seismic evaluation method for steel structures apply to low steel structure buildings, and check whether the anti-lateral force components can satisfy the seismic demand to determine the seismic performance of buildings. Seismic evaluation method for steel structures based on the same theory as seismic evaluation method for reinforced concrete buildings, which include capacticy spectrum method and nonlinear static analysis, and we use ETABS to run nonlinear static pushover analysis. The study collated and recorded 118 steel structure experimental data and proposed the force and deformation plastic hinge curves. Compare the force and deformation curves to ETABS default, FEMA 273, and ASCE 41-13, showing that the force and deformation curves proposed in this study are closer to the experimental results and are conservative. Secondly, through analyzed two gated steel frames and a concentrically braced steel frame, we found that analyzing with force and deformation curves proposed in this study can get results whtch are closer to the experimental reaction than analyzing with ETABS default, FEMA 273, and ASCE 41-13. It shows the force and deformation curves proposed in this study are more reasonable. Last, there are seismic evaluations and explanations for two steel structure buildings.
