One key issue in seismic performance assessment is the scaling of ground motions for nonlinear response-history analysis. This research is in the second phase of a project, which investigates the impact of ground-motion scaling procedures on the distributions of structural responses for tall buildings. In the previous phase of the project, four ground-motions scaling procedures were studied, namely: 1) geometric-mean scaling of pairs of ground motions, 2) spectrum matching, 3) first-mode-based scaling to a target spectral acceleration, and 4) maximum-minimum orientation scaling. In this thesis, three more scaling procedures are investigated, including: modal-pushover-based scaling, distribution-based scaling and Jayaram and Baker’s scaling methods. Nonlinear response-history analyses are conducted to study the distributions of peak floor acceleration, peak story drift and floor spectral acceleration responses of a sample 34-story high-rise building subjected to ground motions scaled using the three methods. The advantages and disadvantages of each method and the impact of scaling on the seismic performance of tall buildings are discussed.140 bytestext/htmlen-US地震歷時記錄縮放耐震性能評估高樓側推分析ground motionsscalingseismic performance assessmenthigh-rise buildingpushoverthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/255484/1/index.html
