摘要
应用弹性地基梁理论,提出了考虑砌体局部受压特点的支承于砌体上的梁端有效支承长度计算模式;同时,利用平截面假定,得到有效支承长度的简化计算模式.根据已有试验结果,建立了有效支承长度计算公式,该公式避免了现行砌体结构设计规范中相应公式的不足,并能考虑上部荷载的影响,且计算结果与试验结果吻合较好.
Based on the elastic theory, a modified mode of effective bearing length is put forward; a simplified mode is also put forward by use of the assumption of plane section. These modes can consider features of local compression of masorny. Formula about effective bearing length are founded by the experiments' results. They can evade shortcomings of the formula in Chinese Code GBJ3-88 and also consider the influence of stress existing in the masonry. The evaluation results have good agreements with the experiments'.
