规范GBJ3-88没有对连续墙梁设计作出规定。现基于 7个两跨连续墙梁的试验结果讨论了其受力性能和破坏形态。对 2～ 5跨连续墙梁进行有限元分析 ,依据其应力和内力分布 ,提出托梁内力计算公式和承载力简化计算方法。基于连续拉杆拱受力模型和砌体双向受压强度导出墙体受剪承载力公式。给出计算实例并与其他设计方法进行了对比。
Specification GBJ3-88 does not provide for the design of continuous wall beams. Based on the test results of seven two-span continuous wall beams, their mechanical properties and failure modes are discussed. Based on the finite element analysis of 2 ~ 5 span continuous wall beams, the calculation formula of internal force of joist and the simplified calculation method of bearing capacity are put forward based on the distribution of stress and internal force. A formula for calculating the shear capacity of a wall based on the model of continuous tie - rod arch and the biaxial compressive strength of masonry. The calculation examples are given and compared with other design methods.
