| Abstract: | This paper presents an experimental study of the stiffness of sixteen SRC beams. The test results are consistent with the two assumptions, the hypothesis of plan section for average strains and the coefficient of the elasto-plastic moment of resisting under service loads being constant. On the basis of the experimental study of the stiffness of SRC beams under shortterm loading, a calculation formula of stiffness of SRC flexural members is proposed which can link up with that of RC flexural members. Another calculation formula of stiffness of SRC flexural members is established by using the method of effective moment of inertia. The calculated results of the two formulas are in accordance with the experimental data. |
