| 摘 要： | 砌体结构在支承处因构造不当而引起挑梁与墙结合面发生裂缝,梁端挠度大于设计值是导致这一缺陷的重要原因之一.本文将埋入砌体的挑梁构件作为以砌体为弹性地基的半无限长梁分析且能解释产生上述问题的原因,并提出了挑梁嵌固长度的确定方法.

| Abstract: | Unsuitable constructions in the bearing of Masonry Structures lead to cracks of the connecting face between the bracket beam and wall. One of the important reasons of the flaw is that beam-end deflection was greater than design value. The paper regards the bracket beam buried Masonry Structures as semi-infinite beam which takes Masonry Structures for elastic foundation, analyzes this beam, and explains reasons which leads to above-mentioned questions. Definitive methods of anchorage length of bracket beam are posed just for reference. |
