    摘要:

    参照国家抗震规范8度设防的标准,制作一榀/2比例的由钢筋混凝土梁和T形截面钢骨混凝土异形柱组成的单跨两层的框架模型。通过拟静力试验,研究了结构的破坏形态、刚度退化、延性与耗能等抗震性能。试验结果表明,T形截面钢骨异形柱框架结构抗震性能良好,柱中钢骨在结构抗震中发挥了明显的作用。试验研究和分析结果表明,钢骨异形柱框架结构的抗震性能可满足抗震设防的要求。

    Abstract:

    Referring to the criterion of seismic fortification intensity 8 specified by national seismic design code, a /2scaled model of single span and twostory frame composed of RC beams and Tshaped steel reinforced concrete (SRC) columns has been made. A seismic evaluation was performed by the quasistatic testing, including failure pattern, stiffness degradation, ductility and energy dissipation. The experimental results show that the frame has good seismic behavior, and section steel in the columns plays an important role in earthquake resistance. On the basis of experimental study and analysis, it concludes that the seismic behavior of frame with SRC specialshaped columns can satisfy the requirements of seismic fortification. 
