配筋砌块短肢砌体剪力墙抗剪承载力研究
|
摘要
建立了配筋砌块短肢砌体剪力墙抗剪承载力的理论分析模式,并在此基础上根据国内59片符合配筋砌块短肢砌体剪力墙基本要求的配筋砌块砌体剪力墙抗剪承载力试验数据,分别考虑了灌孔砌体强度、剪跨比、竖向压力、水平钢筋等因素对抗剪承载力的影响,给出了与试验数据吻合较好的配筋砌块短肢砌体剪力墙抗剪承载力计算公式。与GB 50003—2001《砌体结构设计规范》中配筋砌块砌体剪力墙抗剪承载力计算公式相比,该公式适当增大了灌孔砌体和竖向压力对抗剪承载力的影响,水平配筋利用效率系数随着水平钢筋配筋率和剪跨比的增大而减小。
In this paper,the theories analysis mode of shear capacity of the reinforced block short-leg masonry shear wall has been put forward.Based on the mode,formula for shear capacity was proposed taken into the factors including masonry strength,shear span ratio,vertical load,and horizontal reinforcement.The formula show a good correlation with the experimental data of the collected 59 shear failure tests of reinforced concrete masonry shear walls which are included in reinforced block short-leg masonry shear wall.Compare to the formula for shear capacity of reinforced concrete masonry shear wall given in "Code for Design of Masonry Structures"(GB 50003—2001),the formula in this paper enlarged the contribution of masonry strength and vertical load properly,and the utilization efficiency coefficient of horizontal reinforcement was reduced with the increasing of its reinforcement ratio and the shear span ratio.
