摘　　要：为实现竖缝墙的设计思想,考察带竖缝剪力墙设计方法,提出了补充设计计算和构造措施,包括梁柱连接和梁腹板,应补充受剪强度计算;当受剪强度不满足时,建议增加竖缝墙和钢柱的抗剪件连接,该构造可同时满足安装要求;建议竖缝剪力墙上端与钢梁采用竖向孔高强度摩擦型螺栓连接,以实现竖缝剪力墙不承受竖向荷载,只承受水平力的设计思路.建议参考钢筋混凝土设计规范(GB50010-2002)对竖缝剪力墙受剪承载力进行设计计算.For implementing the design philosophy of the slit wall, this paper provided a review of the design method for slit reinforced concrete wall. Design rules and constructional measures were proposed. The main conclusions are as follows： shear strength check for the beam-column connection and beam web with specially calculated shear force. When the shear strength is not satisfied, an additional shear key is recommended between the column and the slit wall, and the shear connection is also necessary for convenient installation. In order to imple- ment the slit wall＇s design philosophy of carrying horizontal load only, slit holes are recommended in the HSFB connection between slit wall and the top beam. This allows slip to occur, and its vertical load carrying capacity should be limited to the expansion force of the concrete. Based on the design procedure for beam-columns in Chinese code for reinforced concrete structures GB50010 -2002, the shear strength check for the reinforced slit wall is recommended instead of the currently specified method in JGJ99 -98.
