［摘要］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。［关键词］纤维增强混凝土剪力墙; 基于位移的抗震设计方法; 超强系数; 层间位移角; 静力弹塑性方法中图分类号：TU318.1，TU377.9+4 文献标识码：A 文章编号：1002-848X(2016)04-0085-06
Study on displacement-based seismic design method of fiber reinforced concrete shear wall structuresZhang Haobo1, Kou Jialiang1, Liang Xingwen2, Gu Xiaorui3(1 School of Civil Engineering & Architecture, Xi′an University of Technology, Xi′an 710048, China; 2 School of Civil Engineering, Xi′an University of Architecture & Technology, Xi′an 710055, China; 3 Research Institute of Architecture Design, Chinese Academy of Sciences, Xi′an 710065, China)Abstract:According to displacement-based seismic design method, seismic performances of fiber reinforced concrete shear wall were divided into five levels: intact, serviceability, slight damage, medium damage and serious damage. The excellent ductility and toughness of ductile fiber reinforced concrete (DFRC) were used to improve the seismic ability of shear walls, and the super strength coefficient of fiber reinforced concrete shear wall was proposed. Through the control of the horizontal inter-storey drift ratio limit value of all performance levels of the shear wall, the design and calculation steps for all performance levels of the fiber reinforced concrete shear wall structure were given. Through the calculation of seismic performance of actual engineering, it shows that the displacement-based design method of the fiber reinforced concrete shear wall structure is simple and easy to operate. Finally, the shear wall structure was analyzed and verified by using the Pushover analysis method.Keywords:fiber reinforced concrete shear wall; displacement-based seismic design method; super strength coefficient; inter-storey drift ratio; Pushover analysis
