［摘要］為研究裝配式剪力墻結(jié)構(gòu)中預(yù)制內(nèi)嵌外圍護(hù)墻對主體結(jié)構(gòu)抗震性能的影響及為結(jié)構(gòu)設(shè)計(jì)提供依據(jù)，選取了3個典型工程作為案例，對整體結(jié)構(gòu)模型進(jìn)行了彈性分析和彈塑性分析，從結(jié)構(gòu)模態(tài)、層間位移角、層剪力、側(cè)向剛度、整體及局部破壞情況等角度，分析了圍護(hù)墻對結(jié)構(gòu)抗震性能的影響。結(jié)果表明：彈性分析時圍護(hù)墻對主體結(jié)構(gòu)剛度貢獻(xiàn)顯著，導(dǎo)致結(jié)構(gòu)周期減小，層間位移角減小且在圍護(hù)墻起始層存在層間位移角突變現(xiàn)象，層剪力增大；彈塑性分析時與不含圍護(hù)墻的模型相比，含圍護(hù)墻模型的層間位移角減小，層剪力增大，圍護(hù)墻未優(yōu)化時與結(jié)構(gòu)構(gòu)件共同受力破壞，采用優(yōu)化構(gòu)造可顯著減小圍護(hù)墻的不利影響?；诜治鼋Y(jié)果，建議工程中應(yīng)優(yōu)先在圍護(hù)墻與主體結(jié)構(gòu)之間采取有效的隔離措施；當(dāng)圍護(hù)墻未優(yōu)化時應(yīng)根據(jù)工程情況補(bǔ)充進(jìn)行彈塑性分析，并采取局部加強(qiáng)措施。

Abstract:To study the effects of precast embedded enclosure walls on the seismic behavior of main structure in assembled shear wall structure and provide evidence for structural design, three typical projects were chosen as cases, elastic analysis and elastic-plastic analysis were carried out for their whole structural models, the effects of enclosure walls on the seismic behavior of structures were analyzed from the respects of structural modal, story drift, story shear force, lateral stiffness, whole and local damage. It is indicated that enclosure walls make a great contribution for structural stiffness, thus structural period is shorten, story drift decreases and a sudden change appears in the start floor of enclosure walls, and story force increases for the elastic analysis. Compared with the model without enclosure walls, the elastic-plastic analysis of the model with enclosure walls shows that the story drift decreases, the story shear force increases, and enclosure walls without optimization bear loads and fail with structural elements integrally. The negative impact of enclosure walls can be alleviated observably by adopting optimized measures. Based on the analysis results, it is suggested that effective isolation measures should be adopted between enclosure walls and main structure preferentially, elastic-plastic analysis and local strengthening measures could be taken according to the project situation when the enclosure walls without optimization are used.
Keywords:assembled shear wall structure;precast embedded enclosure wall;seismic behavior;elastic-plastic analysis
