梁柱刚度对结构计算模型和内力的影响

 钢筋混凝土框架结构体系是常用的结构体系。现阶段均可采用计算机求得精确解,但一些近似计算的手算方法由于概念清楚,计算简便,在结构方案设计中能快速手算出结构的近似内力,从而得出合理结构方案。本文以内框架房屋为例，详细分析了不同刚度的梁支承于柱，分别按铰支座、框架两种不同模型并考虑活荷载的不利布置，计算并比较梁端的控制截面内力，通过对控制内力的分析，找出不同梁柱线刚下类似结构合理简洁的计算方法,对工程设计有较强的指导意义。

Effect of Beam-column Rigidity on Structure Calculating Model and Internal Force

Reinforced concrete frame is one of the common structure system. Nowadays accurate answer can be got by using computer but because of distinct concept and simple calculation of manually operated algorithm calculation which is approximate calculation.Approximate internal force can be got quickly by the way in the structure design.An example of inner frame houses was taken to analyze beams of different girder on pole,calculate and compare the controlling cross section internal forces according to two different models of hinge support and frame as well as disadvantageous arrangement of live load was considered,to obtain a reasonable and simple calculating method, which was valuable for engineering design.
