钢筋混凝土框架结构是一种由梁、柱组成的超静定结构体系,在地震作用、风荷载等各种荷载组合作用下需设计成延性结构,以很好地吸收和耗散能量,保证结构具有足够的抵抗变形的能力,确保结构的安全性。在工程结构设计中利用钢筋混凝土构件的基本特性,合理地进行框架梁的梁端弯矩的调幅,使框架梁成为耗能构件,从而使整个框架结构成为强柱弱梁结构体系,对于结构抗震设计具有非常重要的意义。
Reinforced concrete frame structure is a kind of statically indeterminate structural system composed of beams and columns. Under the action of various loads such as earthquake action and wind load, the ductile structure needs to be designed to absorb and dissipate energy well to ensure the structure Has enough resistance to deformation of the ability to ensure structural safety. In the engineering structure design, the basic characteristics of the reinforced concrete members are utilized to reasonably carry the amplitude modulation of the beam end moment of the frame beam so that the frame beam becomes an energy-dissipating component, so that the whole frame structure becomes a strong column weak beam structure system, Design is of great importance.
