＜形、L形、T形截面剪力墙配筋研究

为解决<形、L形、T形截面剪力墙配筋设计,参考《复杂截面剪力墙配筋研究》,采用混凝土单轴受压简化应力—应变曲线和应变线性分布的平截面假定,积分计算剪力墙正截面承载力.通过不同纵筋形心位置矩形截面剪力墙正截面承载力骨架曲线比较分析,指出将纵筋设计于边缘构件中不够经济合理.通过<形、L形、T形截面剪力墙承载力骨架曲线分析,并与ACI 318-99,BS 8110-97和GB 50010-2002国内外规范比较,说明本文方法比较安全、可靠、合理.最后通过算例,将本文配筋方法应用于<形、L形、T形截面剪力墙配筋设计,揭示了目前某些软件针对<形、L形、T形截面剪力墙所采取的分段设计方法不够安全合理的隐患.

Research on reinforcement design of shear walls with <,L,T-sections

From 《reinforcement design of shear walls with complex cross sections》,and based on the simplified concrete stress-strain curve and the assumption of linear strain,shear wall loading capacity could be calculated through integral.Then reinforcement of shear walls with <,L,T-sections could be designed.Through the analysis of rectangular shear wall interaction curves for axial force plus bending moment of different reinforcement centroid,it was found that it was not economic enough about shear wall design from reinforcement designed in boundary member.Through the analysis of shear walls with <,L,T-sections interaction curves for axial force plus bending moment from ACI 318-99,BS 8110-97 and GB 50010-2002,this proposed reinforcing method proved to be considered as relatively reliable,safe and reasonable.At last,through an example,the presented reinforcing method was applied to reinforcement design of shear walls with <,L,T-sections.At mean time,it was revealed that reinforcement partitioned design method of shear walls with <,L,T-sections adopted by some software was not safe and reliable.
