按照基于位移的抗震设计方法,将纤维增强混凝土剪力墙结构的性能划分为“完好、轻微损伤、轻度损伤、中度损伤和比较严重损伤”五个水平。利用延性纤维增强混凝土良好的延性和韧性提高剪力墙抵抗地震作用的能力,提出了纤维增强混凝土剪力墙超强系数,通过对剪力墙的各性能水平层间位移角限值的控制,给出了纤维增强混凝土剪力墙结构针对不同性能水平的设计计算步骤。通过对实际工程性能进行计算发现,纤维增强混凝土剪力墙结构基于位移的设计方法简单易行、便于操作。最后利用静力弹塑性方法对剪力墙结构进行了分析验证。
According to the displacement-based seismic design method, the performance of fiber-reinforced concrete shear wall structure is divided into five levels of “intact, minor damage, mild damage, moderate damage and more serious damage.” Based on the ductility and toughness of ductile fiber reinforced concrete to improve the ability of shear wall to resist the earthquake, the super strong coefficient of fiber reinforced concrete shear wall is proposed. Through the control of the limit value of displacement between layers of each performance level of shear wall, The design and calculation steps of fiber reinforced concrete shear wall structures for different performance levels are given. Through the calculation of the actual engineering performance, it is found that the displacement-based design method of fiber reinforced concrete shear wall structure is simple and easy to operate. Finally, the static and elastic elastoplastic method is used to analyze and verify the shear wall structure.
