新型高强混凝土组合剪力墙受剪性能研究
|
摘要
为了提高高强混凝土剪力墙的延性和耗能能力,同时不削弱墙体的刚度和承载力,提出了双钢板高强混凝土组合剪力墙.利用Abaqus有限元分析软件,建立了无暗柱型与方钢管暗柱型两种双钢板高强混凝土组合剪力墙模型,分析了高宽比和轴压比对这两种组合剪力墙承载力和延性的影响,并对外侧钢板与混凝土的相互作用进行了分析.结果表明:随着高宽比的减小,这两种组合剪力墙承载力和弹性阶段刚度明显提高,破坏形态也由弯曲破坏向剪切破坏过渡.随着轴压比增大,无暗柱型组合剪力墙承载力下降,延性降低;方钢管暗柱型组合剪力墙承载力和刚度变化不大,延性呈下降趋势.设置方钢管暗柱可以加强对墙肢的约束,有效提高双钢板高强混凝土组合剪力墙的承载力和延性.
In order to improve ductibility and energy dissipation capacity of high strength concrete shear walls,without weakening stiffness and load bearing capacity of the wall,double-steel plate-type of high-strength concrete composite shear walls are brought forward.Two types of double-steel plate-type of high-strength concrete composite shear walls including a non-conceal column model and a square steel conceal column model are established by using finite element software ABAQUS.Influences of height-width ratio and axial compression ratio on the ductibility and bearing capacity of composite shear walls are analyzed.The interaction between the steel plate and concrete is also studied.The results show that failure mode of shear wall changes from bending failure to shear failure as the height-width ratio becomes smaller,which results in larger load bearing capacity and initial stiffness.Increasing axial compression ratio can lead to reduction in load bearing capacity and ductibility of non-conceal column model much more than square steel conceal column model,due to the restraint of conceal column.Square steel conceal column could strengthen the constraints of wall limb,and effectively improve the bearing capacity and ductibility of high strength concrete composite shear wall.
