［摘要］底部邊界約束對填充墻RC框架結(jié)構(gòu)抗側(cè)性能影響明顯，考慮底部約束效應(yīng)，合理計算填充墻框架結(jié)構(gòu)側(cè)移剛度及其水平抗力的設(shè)計方法亟待形成。采用ANSYS程序?qū)?個單層單跨填充墻框架模型進行非線性仿真分析并與其試驗結(jié)果對比驗證之后，建立了3個單層單跨和3個兩層單跨不同開洞率的填充墻框架結(jié)構(gòu)模型，模擬分析了底部邊界約束對填充墻RC框架結(jié)構(gòu)抗側(cè)性能的影響，得出了底部構(gòu)件越剛，墻體所受約束更強，墻體受力區(qū)域及其傳力路徑越優(yōu)，結(jié)構(gòu)抗側(cè)承載力及側(cè)移剛度越大等結(jié)論。

Abstract:The bottom boundary constraint has obvious influence on the lateral resistance performance of RC frame structure with infilled wall. Considering the effect of the bottom boundary constraint, the design method of reasonable calculating lateral stiffness and horizontal resistance of RC frame structure with infilled wall is urgently to be formed. After the nonlinear simulation analysis on 3 single-storey and single-span infilled wall RC frame structure test models by ANSYS and comparison with the test results, 3 single-storey and single-span as well as 3 two-storey and single-span infilled wall RC frame structure models with different opening rates were built for simulating and analyzing the influence of the bottom boundary constraint on the lateral resistance performance of RC frame structure with infilled wall. Analysis results that the stronger the stiffness of the bottom component is, the more constrained the wall is, and the more reasonable the wall stress area and the force transmission path is, the greater the lateral resistance bearing capacity and lateral stiffness of the structure is were concluded.
Keywords:bottom boundary; infilled wall; RC frame structure; lateral resistance performance; nonlinear simulation analysis
