生态复合墙体在竖向荷载作用下,墙体各组件(边框、肋格、填充砌块)之间存在协同工作关系。采用弹性地基梁理论,建立生态复合墙体在竖向荷载作用下的内力计算模型,定量地计算出各组件在竖向荷载作用下承担的内力,分析影响墙体受力分配关系的因素。理论分析与试验结果对比表明:该计算模型运用于竖向荷载作用下的生态复合墙体内力计算具有一定的精确度;各组件分配竖向荷载比例与暗梁刚度、边框柱刚度及复合墙板等效弹性模量等因素有关,边框柱刚度的影响小于暗梁刚度影响;当复合墙板等效弹性模量增大至30 GPa时,边框柱承担的荷载只占总荷载的18.4%。该研究结果为生态复合墙结构的抗震优化设计提供了一定的参考。
Ecological composite wall under the vertical load, the wall of the various components (frame, ribs, filling block) there is a synergistic relationship between work. Based on the theory of elastic foundation beam, the internal force calculation model of ecological composite wall under vertical load is established. The internal forces of each component under vertical load are calculated quantitatively, and the factors influencing the stress distribution of wall are analyzed. The comparison between the theoretical analysis and experimental results shows that the calculation model has some accuracy in calculating the internal force of the ecological composite wall under the vertical load. The distribution of the vertical load ratio, the rigidity of the hidden beam, the rigidity of the frame column and the composite wallboard Equivalent elastic modulus and other factors, the influence of the frame column stiffness is less than that of the hidden beam. When the equivalent elastic modulus of the composite wallboard increases to 30 GPa, the load on the frame column accounts for only 18.4% of the total load. The results of this study provide a reference for the seismic design optimization of ecological composite wall structure.
