组合荷载作用下钢筋混凝土框架梁内力的方法研究
|
摘要
在钢筋混凝土框架结构的房屋设计中,结构构件的内力计算是整个框架结构设计的基础。其中梁的设计是框架结构设计中的一个重要组成部分。本文根据力学原理,提出了荷载组合的原理,得到一种在组合荷载作用下框架梁内力的实用计算方法,适用在荷载的最不利组合情况下计算梁的内力;接着分别叙述在横向荷载作用下与竖向荷载作用下梁中内力的算法,最后将横向荷载与竖向荷载进行组合,在荷载的最不利情况下算出梁中的内力,为工程优化设计提供了有力的依据。
In the design of the building of RC frame,the calculation of the internal force of the components is the foundation in the design of the building of RC frame.And the design of the beams is one important part of the whole design of building.A practicle approach for the internal force of beams of RC frame under combined loads was given according to the principle of mechanics.First the principle of the combination of loads is given,it thinks that we should calculate internal force of the beams under the most dangerous combination of loads.Then the approaches for internal force of beams under lateral loads and vertial loads were given.At last,it combines the lateral loads and the vertial loads,and the internal force of the beams of RC frame under the most dangerous combined loads was calculated.This methods present advantage dependence.
