摘要
以1∶2比例的格构式-轻骨料钢筋混凝土组合墙体为研究对象,对页岩为轻骨料的钢筋混凝土组合墙体进行了水平剪力作用和压弯作用下的静载试验研究。试验主要分析了组合式墙体在破坏过程中的破坏形式、承载力、裂缝开展、以及变形性的受力特征。实验结果表明,抗剪承载力大于压弯承载力,属于墙板弱柱型破坏;压弯作用下的主要破坏模式为弯曲型破坏,整体的抗弯刚度较小。实验结果可为研究格构式-轻骨料钢筋混凝土组合墙体正截面承载力计算理论及设计方法提供依据。
Using 1/2-scaled lightweight aggregate concrete combination wall in lattice as the research object,the action of static load research is tested by hale for lightweight aggregate concrete composite wall under bending and horizontal functions beyond shear.The combined wall is also analyzed in the process of destruction,the destruction form,bearing capacity,crack propagation,the deformation force characteristic.The experimental result shows that the shear bearing capacity is greater than the bending type capacity,which belongs to the type wallboard weak column destruction.The action of the main failure mode as bending damage,and the overall bending stiffness is small.Experimental results for the lattice lightweight aggregate concrete composite wall body theory and it provides the basis design for calculating the ultimate bearing capacity of normal section.
