［摘要］填充墻對于框架結構的抗震性能有很大的作用。為了探究有無填充墻、填充墻的數(shù)量以及填充墻的布置對于結構動力特性的影響，采用等效斜撐建立了基于SAP2000的3個填充墻的等效模型，并對其進行了模態(tài)分析、反應譜分析、Pushover分析和非線性時程分析。分析結果表明，填充墻的加入對于結構的周期有明顯的折減，對于結構塑性鉸的發(fā)展有很大的抑制作用，其不規(guī)則布置對結構薄弱層有較大的不利影響。
［關鍵詞］填充墻； 非線性； Pushover； 塑性鉸

Abstract:Infill wall has large impact on seismic performance of frame structure. In order to explore the effects of existence, amount and arrangement of the infill wall on the dynamic characteristics of the structure, the equivalent diagonal bracing was used to establish three equivalent models of the infill wall based on SAP2000 and modal analysis, response spectrum analysis, pushover analysis and nonlinear time-history analysis were conducted. Results show that the existence of the infill wall obviously reduces the structural period, and largely restrains the development of plastic hinge and its irregular arrangement has great negative effects on the weak layer of the structure.
Keywords:infill wall; nonlinear; Pushover; plastic hinge
