该文研究型钢高性能混凝土(SHPC)剪力墙在不同参数影响下的抗震性能,采用纤维墙元模型对SHPC剪力墙进行数值分析,并将数值分析结果与试验结果进行对比,验证了纤维墙元模型的合理性和可靠性。在此基础上,分析了轴压比、边缘构件约束区长度及型钢配钢率对SHPC剪力墙抗震性能的影响,结果表明,SHPC剪力墙承载能力随轴压比的增大而提高,变形能力随轴压比的增大而降低,当设计轴压比达到0.5时,其位移延性系数小于3;对于高轴压比SHPC剪力墙,适当增加边缘构件约束区长度,试件的变形能力有所改善;型钢配钢率的变化对承载能力的影响比对变形能力的影响更为显著。
In this paper, the seismic behavior of SHPC shear walls under the influence of different parameters is studied. The numerical simulation of SHPC shear wall is carried out by using the fiber wall element model. The numerical analysis is compared with the experimental results. Wall element model of rationality and reliability. On this basis, the influence of axial compression ratio, length of restraint zone of edge member and steel ratio on steel SHPC shear wall is analyzed. The results show that the bearing capacity of SHPC shear wall increases with the increase of axial compression ratio, The deformation ductility decreases with the increase of axial compression ratio. When the designed axial compression ratio reaches 0.5, the displacement ductility coefficient is less than 3. For the SHPC shear wall with high axial compression ratio, the constraint zone length is increased appropriately, Ability to improve; steel with steel changes in the load carrying capacity than on the deformation capacity of the more significant impact.
