［摘要］按照基于位移的抗震設(shè)計(jì)方法，將纖維增強(qiáng)混凝土剪力墻結(jié)構(gòu)的性能劃分為“完好、輕微損傷、輕度損傷、中度損傷和比較嚴(yán)重?fù)p傷”五個(gè)水平。利用延性纖維增強(qiáng)混凝土良好的延性和韌性提高剪力墻抵抗地震作用的能力，提出了纖維增強(qiáng)混凝土剪力墻超強(qiáng)系數(shù)，通過(guò)對(duì)剪力墻的各性能水平層間位移角限值的控制，給出了纖維增強(qiáng)混凝土剪力墻結(jié)構(gòu)針對(duì)不同性能水平的設(shè)計(jì)計(jì)算步驟。通過(guò)對(duì)實(shí)際工程性能進(jìn)行計(jì)算發(fā)現(xiàn)，纖維增強(qiáng)混凝土剪力墻結(jié)構(gòu)基于位移的設(shè)計(jì)方法簡(jiǎn)單易行、便于操作。最后利用靜力彈塑性方法對(duì)剪力墻結(jié)構(gòu)進(jìn)行了分析驗(yàn)證。［關(guān)鍵詞］纖維增強(qiáng)混凝土剪力墻; 基于位移的抗震設(shè)計(jì)方法; 超強(qiáng)系數(shù); 層間位移角; 靜力彈塑性方法中圖分類(lèi)號(hào)：TU318.1，TU377.9+4 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：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
