谈谈砼梁的实用快速配筋方法

ON PRACTICAL AND QUICK METHOD OF STEEL BARS ALLOCATION OF CONCRETE BEAMS

文章通过对梁的荷载与内力的某些内在关系的分析，并通过分析设计、施工中的具体操作中的一些情况，提出了用“减去法”确定梁内各区段的箍筋配置，用“累加法”配置梁内纵向受力钢筋的方法。从而，解决了实际工程中，如何既快速简洁而又合理地配置砼梁内的钢筋问题。对实际设计工作具有指导和参考作用。另外，通过对钢材浪费情况的分析，提出了尽量减少配箍量是节省钢材、减少含钢量的观点与方法。参２。

In this paper, the writer, basing on the analysis of the internal relationships between loads and forces on beams, the conditions of practical manipulation, comes up with a method of hooping bars allocation in each area of beams by subtracting and forcing bars allocation by accumulating.Thus the problem has been solved of how to allocata steel bars explitly quickly and reasonably. It can direct practical designs and thus can be refered by designers. In addition, after analysing the waste of steels, the writer also raises a better method of saving steels and reducing steel areas ratio by reducing hooping ratio.2refs.
