ABAQUS模拟现浇剪力墙与自复位剪力墙

摘要

Self-restoring shear wall and traditional cast-in-place shear wall were simulated by using ABAQUS software.The load performances of Self-restoring shear wall and traditional cast-in-place shear wall under reciprocating load were introduced.The characteristics of Self-restoring shear wall as a new type of structure were introduced.According to the results of simulation and analysis,the differences in bearing capacity,damage and energy dissipation of self-restoring shear wall and traditional cast-in-place shear wall were explored,and the effect of bending moment ratio of different energy-consumption reinforcing bar on its working performance was investigated.Results show that the bearing capacity of self-restoring shear wall is slightly lower compared with cast-in-place shear wall.On structure deformation damage control under loading,self-restoring shear wall is better.On the energy dissipation,cast-in-place shear wall is better.The energy dissipation performance of self-restoring shear wall increases with the increase of bending moment ratio of energy-consumption reinforcing bar.%运用ABAQUS对自复位剪力墙及传统现浇剪力墙进行数值模拟分析,对比二者在往复荷载作用下的工作性能,介绍自复位剪力墙这一新型结构的特点.根据模拟分析结果,探寻了自复位剪力墙和现浇剪力墙在承载力、破坏及耗能方面的差异,并考察自复位剪力墙耗能钢筋弯矩配比不同对其工作性能造成的影响.结果表明:自复位剪力墙的承载力相对于现浇剪力墙稍低,在荷载作用下对结构的变形损伤控制自复位剪力墙更具有优越性,而耗能能力现浇剪力墙则较好;自复位剪力墙随耗能钢筋弯矩配比的增加,耗能性能有所改善.
