基于ABAQUS的少筋混凝土剪力墙抗震性能的数值模拟

Numerical Simulation on Seismic Behaviors of Less-Reinforced Concrete Shear Walls Based on ABAQUS

少筋混凝土剪力墙可以应用于不高于7度的抗震设防区的中高层住宅中,能够大幅度降低工程造价,因此具有良好的市场应用前景和很高的经济效益.利用ABAQUS软件对现浇少筋混凝土剪力墙进行有限元模拟计算,初步分析少筋混凝土剪力墙的破坏形态以及抗震性能.计算结果表明,少筋混凝土剪力墙在低轴压比情况下破坏时为弯剪破坏,变形能力足够.

Less - reinforced concrete shear wall can be applied to no more than 7 degree seismic fortification of up- per and under in the residence, as well as can greatly reduce the project cost, therefore it has the good market appli- cation prospect and high economic benefits. In this paper, by using ABAQUS software of cast - in - place reinforced concrete shear wall with less finite element numerical simulation, preliminary analysis less failure pattern and seis- mic performance of reinforced concrete shear wall, the concrete research to provide the reference for later. Calcula- tion results show that less reinforced concrete shear wall is destroyed under the condition of low axial compression ratio for bending shear damage, deformation capacity.
