配筋砌块砌体剪力墙平面外偏心受压承载能力试验研究

通过对16片不同偏心距配筋砌块砌体墙片的平面外偏心受压的静力加载试验,了解了配筋砌体墙片在平面外偏心荷载作用下的破坏形态及机理、承载能力与变形特征,以及竖向钢筋在不同偏心距时的受力特性。将各墙片的承载力试验结果与《砌体结构设计规范》(GB50003—2001)的规定进行了对比分析,并提出相应的改进意见。探讨了配筋砌体剪力墙平面外竖向承载力的影响因素,为建立承载力计算方法提供了依据。

Experimental Research on out of Plane Eccentric Compressive Bearing Capacity of Reinforced Block Masonry Shear Walls

16 reinforced concrete masonry walls have been tested under out of plane eccentric load.The form and mechanics of failure,the bearing capacity,the characteristics of deformation and mechanical behavior of vertical bars under varying eccentricities are learned.The test results are compared with the predicated values recommended by the Code for Design of Masonry Structures,and new opinions are put forward.Influence factors of reinforced block masonry shear walls bearing capacity out of plane are discussed,which can provide reference for the calculation of bearing capacity on reinforced block masonry shear wall structure.
