摘要
与普通钢筋混凝土剪力墙结构相比,CFRP筋-钢筋混凝土剪力墙结构具有较好的抗震性能和可恢复性。基于CFRP筋-钢筋混凝土剪力墙构件的破坏过程和第五代中国地震动参数区划图,提出了更高的抗震设防目标,并将CFRP筋-钢筋混凝土剪力墙结构性能划分为良好使用、微修后使用、修复后使用、生命安全四个水平。利用不同变形指标,统计CFRP筋-钢筋混凝土剪力墙结构在各性能水平下的受力层间位移角限值、层间位移角限值、残余变形限值。采用等效弹性位移反应谱对CFRP筋-钢筋混凝土剪力墙结构进行基于位移的抗震设计,通过算例验证此设计方法用于该结构的可行性。
Compared with ordinary reinforced concrete shear wall structure, CFRP-reinforced concrete shear wall structure has good seismic performance and recoverability. Based on the failure process of CFRP-reinforced concrete shear wall members and the fifth-generation Chinese ground motion parameter zoning map, a higher seismic fortification goal was proposed. And the CFRP-reinforced concrete shear wall structure performance was divided into four levels: good use, use after micro repair, use after repair and life safety. Different deformation indexes were used to calculate the limit value of the physical inter-story displacement angle, the inter-story displacement angle and the residual deformation of the CFRP-reinforced concrete shear wall structure under various performance levels. The equivalent elastic displacement response spectrum was used to carry out the displacement-based seismic design of the CFRP-reinforced concrete shear wall structure, and the feasibility of this design method for the structure was verified through a calculation example.
