摘　　要：在剪力墙截面两端采用暗柱作为约束边缘构件,并对暗柱分段封闭箍筋;利用局部无黏结技术,在剪力墙端部h/4的墙宽度范围内靠内侧受力纵筋外部套上塑料套管阻止钢筋与混凝土黏结;然后用ANSYS9.0分析了剪力墙的破坏形态、承载力、裂缝开展等性能.分析结果表明,与以往普通方案相比,采用局部无黏结方案,裂缝发展比较充分,延性系数和耗能能力都有显著提高.Hide column as a constraint on the edge component at both ends of the shear wall cross-section,and the hide column segmented closed stirrups.The use of local non-bonding technology in shear wall ends one-fourth wall width,puts plastic sleeve around force longitudinal reinforcement on the inside to prevent adhesion between reinforcement and concrete.Then use ANSYS 9.0 software analysis of shear wall failure modes,bearing capacities,cracks development and other capacities.The results show that,the local non-bonding scheme compared to the previous ordinary scheme,cracks developed fully,ductility factor and energy dissipation capacity has been significantly improved.
