下撑式组合梁在工业建筑中时常遇到,但其计算方法却十分繁杂,目前尚无简便的图表可查,如通过较复杂的微积分运算求解,则冗长繁杂的数学推导往往给设计者带来困难。本文说明了下撑式组合梁在均布荷载下的解析方法,其中图乘法、积分法、近似法这三种方法都经过了数学推导,所得出的三个求解公式简单、精确、实用,从而达到快速计算的目的,可供设计参考使用。
Underslung composite beams are often encountered in industrial buildings, but their calculation methods are very complicated. At present, there are no simple charts available. For example, through complicated calculus operation, long and complicated mathematical derivation is often given to designers. Bring difficulties. This paper describes the analytic method of the stay-supported composite beam under uniform load. The three methods of graph multiplication, integral method and approximate method have been deduced by mathematics. The three solved formulas are simple, accurate and practical, so as to achieve rapid The purpose of the calculations is for design reference use.
