摘　　要：完成了一片设置构造柱的混凝土砌块墙体的局压承载力试验。利用ANSYS有限元分析软件,对构造柱解决局压问题进行了扩大参数的非线性有限元分析,并同不设构造柱的情况进行了对比,验证了混凝土构造柱对改善砌块墙体局压的贡献。试验与有限元分析结果表明局部荷载处设置构造柱后,大部分荷载由构造柱承担,较大程度提高了墙体的局压承载力。最后给出了用构造柱承担局部压力的局压承载力计算方法。Experiment study on the local bearing of one specimen of concrete block wall with construction columns is conducted. The program ANSYS is used to analyze the influences of some other parameters on the local bearing and the analysis results are compared with walls without the column. The contribution of the column to the local compression is validated. The results of experiment and analysis indicate the construction column bear a majority of local load and greatly improve the carrying capacity of concrete block wall in the condition of setting the column in concrete block wall under local compression. The formulas of local bearing capacity of concrete wall with the columns are pro-posed.
