摘要
本文介绍了4榀1/2比例模型的密肋复合墙体在竖向荷载作用下的受力性能试验,由试件的破坏过程和特征以及试验数据,研究了竖向荷载作用下复合墙体的破坏模式、高厚比对墙体承载力的影响、砌块对墙体抗压的贡献、肋梁的作用、轴力在边框柱、肋柱和砌块间的分配及其协同工作性能等受力性能,分析了复合墙体轴心受压承载力的影响因素,为建立计算公式提出了建议,试验和计算数据可为进一步确定计算参数提供依据。
The paper presents the test of four multi-ribbed compound walls in 1/2 ratio on vertical load. According to the damage process and test data of the specimens, this paper makes performance study in damage pattern of the compound wall, affect of ratio of height to depth for beating capacity of the wall, contribution of in-filled block for anti-compress of compound wall, effect of the ribbed-beam, axial force distribution and teamwork between frame column, ribbed-column and in-filled block, and makes analysis in the influencing factors of bearing capacity in uniaxial compressive of the compound wall, The paper put forwards suggests for creating calculation formula of beating capacity, and provides test basis for further determining parameters.
