基于框架结构的铁路房建弯矩调幅计算

Amplitude is calculated based on the railway housing construction moment frame structure

钢筋混凝土框架结构是铁路房建工程中常见的结构形式,框架梁在荷载的作用下,会出现塑性内力重分布的情况,主要是由混凝土裂缝所引力,导致钢筋的锚固出现移动的情况,形成塑性铰而产生转动力。因此,采用"弯矩调幅法"来考虑内力的重分布情况。

Reinforced concrete frame structure of the railway construction in the common room structure, framework beams under load effect, there will be cases of plastic redistribution of internal forces, mainly by the gravitational concrete cracks, leading to anchoring steel case appear to move form a plastic hinge rotation force generated. Therefore, the ＂moment modulating＂ to consider re - distribution of internal forces.
