- Synopsis
- Elastic-plastic behaviors of steel reinforced concrete (SRC) beam-columns under earthquake loading were evaluated well by skeleton curves consisted of the following four points : happening point of transverse tension crack of concrete, flexural yield point, maximum strength point and maximum deformation point. Dimensions of encased steel, strength of materials, hoop ratio and axial load ratio affect the behaviors of beam-columns. In this paper, It was studied by an experimental study and a numerical analysis that quantitative difference of those parameters effects on behavior and skeleton curves of SRC beam-columns encased simple H-shaped steel, and formulae of hysteresis characteristic of SRC columns under earthquake loading were proposed.
