摘要: 豎向分布筋不連接裝配整體式剪力墻(SGBL 裝配整體式剪力墻)特點包括:剪力墻中豎向分布鋼筋在樓層處斷開連接,兩端邊緣構(gòu)件采用現(xiàn)澆做法同時加大主筋配筋,因此 SGBL 裝配整體式剪力墻內(nèi)部不需要采用傳統(tǒng)的裝配整體式剪力墻豎向鋼筋連接方式,極大提高了施工效率. 以某實際工程為研究對象,通過 ETABS 軟件對SGBL 裝配整體式剪力墻結(jié)構(gòu)模型開展動力彈塑性時程分析,驗證了 SGBL 裝配整體式剪力墻結(jié)構(gòu)在大震作用下的抗震安全性. 不同地震工況分析結(jié)果表明,罕遇地震工況下模型層間位移角滿足彈塑性層間位移角 1 / 120 限值要求,SGBL 裝配整體式剪力墻結(jié)構(gòu)模型底部坐漿層保持完好,滿足安全性能要求.

Abstract: The characteristics of the monolithic assembled concrete shear wall structure with non-connected verticaldistribution reinforcement (SGBL monolithic assembly shear wall) include that the vertical distribution reinforcements areunconnected at the floor, the boundary elements at both ends are cast-in-situ and the main reinforcement is increased at thesame time. Therefore, SGBL monolithic assembly shear wall structure does not need to adopt the vertical reinforcementconnection mode of traditional monolithic assembled concrete shear wall structure, which greatly improves the constructionefficiency. Taking a practical engineering as the research object, the dynamic elastic-plastic time-history analysis of SGBLmonolithic assembly shear wall structure model was carried out by ETABS software, and the seismic safety of SGBLmonolithic assembly shear wall structure under rare earthquakes was verified. The analysis results under different seismicaction conditions show that the model interlayer displacement angle meets the 1 / 120 limit value of elastic-plastic interlayerdisplacement angle under rare earthquakes, and the bed-mortar connection layer of SGBL monolithic assembly shear wallstructure model remains intact, meeting the safety performance requirements.
