- 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.
