Research on Reinforced Concrete Pier Second-Order Effect
Abstract: The development and application of reinforced concrete pier second-order effect calculation method have been introduced in this paper. Compared with the law of the change of moment merely implied on simple structures, the elastic finite element method, based on reduced rigidity and using reduction factor to consider the no-linear effect, has an extensive applicability. As for the elastic finite element method, this paper compared the different values of reduction factors in the concrete design code of China and the United States. In numerical examples, three methods are applied to calculate the influence of second-order effect on the moment at the bottom of single pier. The results show that the law of the change of moment is conservative.
