【摘要】 目的研究一种新型带加劲肋钢板的混凝土剪力墙的力学性能.方法利用ABAQUS有限元软件在剪力墙顶端加侧向位移,针对不同参数如轴压比,剪力墙厚度,钢板厚度等的剪力墙的力学性能进行研究,分析剪力墙的承载力和屈服位移.结果剪力墙的承载能力随着内置于剪力墙的钢板厚度,剪力墙的厚度,轴压比,混凝土强度等级的增加而增加.带加劲肋钢板的剪力墙比普通混凝土剪力墙的承载能力和屈服位移都有很大的提高,钢板对剪力墙屈服后强度的提高有很大帮助.结论带加劲肋的钢板内置于剪力墙中能大幅度提升剪力墙的单调荷载下的力学性能.更多还原

【Abstract】 The mechanical behavior of concrete shear walls with built-in ribbed stiffener and steel sheet were analyzed.Horizontal displacement was put on the top of the shear walls by the ABAQUS software.Different parameters of the shear wall were discussed,for instance the axial load ratio,the wall thickness,the built-in steel sheet thickness of the shear walls.The bearing capacity and yield displacement of the shear walls were discussed.The bearing capacity increases with the increase of the axial compression ratio,the wall thickness,the built-in steel sheet thickness and the concrete strength grade of the shear walls.The built-in steel sheet with stiffener can improve the structural property of the shear wall greatly.Conclusions can be drawn that the built-in steel sheet with ribbed stiffener can improve the mechanical property of the concrete shear wall with built-in steel sheet and ribbed stiffener greatly under monotonic loading.更多还原
