摘要

本論文針對純構架、含RC牆構架、含磚牆構架等構架形式，在其可能產生塑鉸處，加上塑鉸特性如：軸力-彎矩互制塑鉸、剪力塑鉸、軸力塑鉸等，並參考FEMA273、FEMA356中對塑鉸性質的相關規定，配合等值斜撐模擬，利用SAP2000商業軟體進行側推分析，將得到側向力與變形曲線與實驗結果比對，判驗證其合理性及準確性，提供工程師將來設計分析參考之用。

Fourteen reinforced concrete frames with or without an infill were constructed and tested under horizontal cyclic loading. Analysis using structural models that integrated the ideas of equivalent diagonal strut and nonlinear pushover analysis was performed on these frames. Force-deformation relation of frames established based on ACI 318, FEMA-356, and recommendations by other researchers were presented and compared with test results. Load-deformation relationship of individual components were also obtained from trial-and-error and compared with FEMA or ACI provisions. Possible shear failure mechanism and the effects of infills on the behavior of the frame were also identified in this research. Conclusions of this study would provide engineers a practical reference during the analysis of building retrofit.
