速成墙板的抗剪性能试验研究

Tests of Shear Performance of Rapid Walls

为掌握速成墙板的受力性能,为理论分析和工程设计提供试验数据,进行了未灌混凝土墙板(SGB)和灌混凝土墙板(HSGB)的抗剪承载力试验.试验表明:未灌混凝土墙板抗剪承载力明显低于灌混凝土墙板,在抗震设防地区必须利用灌混凝土墙板的方案进行工程设计;墙板的轴向应力直接影响其抗剪承载力.根据试验和理论分析,建立了抗剪计算公式,以供工程应用参考.

Rapid wall is a new type wall. The theoretical analysis and application of the wall are still in the preliminary stage. To master the mechanic property of the wall and to provide experimental datum for theoretical analysis and engineering design, the shear tests of the rapid wall and the wall with concrete column are carried out. The test results show that the shear bearing capacity of the wall without concrete column is less than the capacity of the wall with concrete column, that the wall with concrete column should be used in the aseismic structure and that the shear capacity of the wall is affected by the axial stress. Finally, according to the experimental result and theoretical analysis, shear formula of the wall with concrete column is deduced, which will be the reference of the engineers.
