摘要
利用静力平衡条件及变形协调条件得出了梁端在砌体上的有效支承长度公式,该公式是假定矩形截面简支梁在均布荷载作用下其挠度L/m时得到a0的一般计算公式。若荷载形式及挠度不同就可按本法去直接求解相应的a0值,同时也与规范公式进行了简单的比较。由于规范采用的是经验公式,计算参数少,试验数量也有限,其结果只有部分数据与本公式相吻合。
In this article,using static balance conditions and deformation compatibility conditions,the formula of effective support length of beam end on masonry was obtained. The formula has a assumption of rectangular sectionsimple supported beam under uniform load. This assumption deflection is L /m. If load form and deflection are different,the method is used to get a0 directly. The formula in this paper was compared with conventional formula.Owing to the empirical formula in the present standard code,few calculation parameters and limited experiment quantity,the results are only consistent with partial data.
