在钢筋砼杠架结构中加入偏心支撑，提高了结构的抗侧刚度，改善了结构的承载能力和耗能能力。对偏心支撑钢筋砼框架结构的耗能梁进行了弹塑性静力分析，提出了它由延性破坏到脆性破坏的分界线；得出了它在弹性阶段及弹塑性阶段的内力分布情况；并采用砼劈裂强度计算模型，推导了它的抗剪强度计算公式，计算结果与实际破坏情况符合较好。 Eccentric support is added to the reinforced concrete truss frame structure, which improves the structural lateral stiffness and improves the bearing capacity and energy dissipation capacity of the structure. Elasto-plastic static analysis was performed on the energy dissipation beam of eccentrically-supported reinforced concrete frame structure, and its boundary line from ductile failure to brittle failure was proposed; the distribution of internal forces in the elastic and elastoplastic stages was obtained; The splitting strength calculation model was derived and its shear strength calculation formula was deduced. The calculated results are in good agreement with the actual damage.
