| 摘 要： | 针对全钢筋混凝土框支剪力墙在工程中所存在的问题,提出了采用比强度高、耐腐蚀性能好、自重轻但弹性模量低并具有线弹性性能的纤维增强塑料(FRP)筋来替换该剪力墙中部分钢筋的建议.通过拟静力试验及非线性有限元数值分析,比较了1榀全钢筋混凝土框支剪力墙试件(FSW-1)和1榀部分配置FRP筋框支剪力墙试件(FSW-4)的裂缝发展规律和破坏模式,及其承载能力、延性性能和滞回特征.结果表明:部分配置FRP筋框支剪力墙结构具有较高的承载能力和较好的抗震性能;非线性有限元分析结果与试验结果吻合较好.

| Abstract: | To solve the problem of frame supported shearwall structure with steel reinforced concrete in construction, the scheme that some steel bars in the structure are partly replaced by fiber reinforced plastic(FRP) bars with high strength allocation, good corrosion resistance, light quality, low elastic modulus and linear elastic properties was proposed. Thus, 2 pieces of frame supported shearwall, which were configured by sheer steel reinforced concrete(FSW 1) and some FRP bars reinforcement concrete(FSW 4) have been sampled. A pseudo static test and a nonlinear finite element analysis were conducted so as to explore properties of frame supported shearwall structure partially configured by FRP bars, such as cracks development law, failure mode, bearing capacity, ductility and hysteretic characteristics. The results show that the bearing capacity and seismic performance could be improved for the frame supported shearwall structure partially configured by FRP bars. Additionally, the results of the nonlinear finite element analysis agree well with the experimental data. |
