摘　　要：针对规范GBJ3-88中墙梁设计方法存在的问题进行研究 ,提出补充和改进建议。通过简支墙梁的有限元分析摸清其应力和内力分布 ,提出托梁内力近似计算公式和承载力简化计算公式 ,并改进了墙体验算。给出了计算实例并与其他设计方法进行了对比。A study is carried out about the imperfection for design methods of the wall beams in the Code GBJ3-88,and the suggestions of improvement and supplement are presented. The distribution of stresses and inner forces of the simply\|supported wall beams by the finite element analyses is groped for. The approximate calculation for inner forces of the bressummer and the simplification of calculation for bearing capacity of the beams are presented and the calculation of the walls in the wall beams is bettered. The calculated example and the comparison between the method and other methods are given.
