| 摘 要： | 以底框结构的实际工程为例,采用有限元方法分析了不同尺寸的连续托梁对托梁所传递剪力占总竖向荷载百分比的影响规律,拱效应形成高度的变化规律.对模拟分析法与本地区习用的计算方法进行了比较,结果表明:模拟分析法更贴近底框结构的实际受力状况,且能准确地计算出其应力分布.应从结构受力和经济的角度来确定连续托梁的尺寸、配筋.

| Abstract: | Based on the practical engineering, adopting the finite element method, the proportion of shear force transmitted by continuous beam to total vertical loading and the height of arch in masonry wall affected by different cross sections of continuous beam supporting masonry wall are discussed. Besides, the results of calculation using analysis method imitating reinforced concrete are compared with those obtained from original methods. The calculation predicted that the exact results can be got by using analysis method imitating reinforced concrete. The cross section size and reinforcement of the beam should be given according to the structure load-bearing conditions and economy. |
