摘要
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。
The design regulations of continuous wall beams are not made in the Code GBJ3-88. The behaviour and modes of failure for continuous wall beams are discussed based upon the test results of 7 specimens. The finite element analyses of 2～5 span continuous wall beams are carried out, and the formulas for inner forces of bressummer and the simplified calculating methods of bearing capacity for the continuous wall beams are presented. The formulas of shear capacity for the walls of continuous wall beams are worked out based upon the force model of continuous arch and the strength of two way compression of masonry.The calculated example and comparison between this method and others are given.
