中文摘要 | 本文提出訂定推覆分析中RC牆塑性鉸性質之有效方法。分析時運用Response-2000及Membrane-2000程式獲取鋼筋混凝土牆構件的側向剪力與牆變位關係,並且依據鋼筋混凝土牆構件在開裂;極限強度及破壞時的側向剪力與牆變位,定義出一參數α值,再透過大量含鋼筋混凝土牆RC構架試驗的結果求得另一修正參數β值之分佈以及迴歸公式,以此α、β二值之乘積建立含鋼筋混凝土牆RC構架塑性鉸性質的設定規則,並以額外之試驗結果驗證此一設定方法之合理性。本文之方法可作為使用SAP2000或ETABS軟體的結構工程師運用次結構(Substructure)分析之方式進行性能設計(Performance Design)或耐震評估時之參考。 |
英文摘要 | In this paper, a method for the determination of the parameters of plastic hinge properties (PHP) for structure containing RC wall in the pushover analysis is proposed. Nonlinear relationship between the lateral shear force and lateral deformation of RC wall is calculated first by the Response-2000 and membrane-2000 code. The PHP (plastic hinge properties) value of each parameter for the pushover analysis function of SAP2000 or ETABS is defined as the product of two parameters α and β. Values of α at states of cracking, ultimate strength and failure of the concrete wall under shear loading can be determined respectively from the calculations by Response-2000. While the corresponding β value of each PHP parameter is obtained from the regression equations calibrated from the experimental results of pushover tests of RC frame-wall specimens. The accuracy of this newly proposed method is verified by other experimental results. It shows that the presented method can effectively assist engineers to conduct the performance design of structure containing RC shear wall using the SAP2000 or ETABS codes. |
