Stiffness Reduction Factor of Reinforced Concrete Bridge Pier Considering Characters of Nonlinear
The method of stiffness reduction had been adopted to consider nonelastic characteristics of reinforced concrete in concrete structure standard of the United States and Canada. Concrete structure design code of China also accepted the method of stiffness reduction as a supplementary way to solve the second-order effects problem when necessary. However, bridge code of China still uses amplified coefficient of eccentricity to consider nonlinear characteristics of reinforced concrete. In view of the absence of investigation in the stiffness reduction of reinforced concrete bridge pier, this paper adopts the numerical integral method to computerize simulation and analyze the regulation of the stiffness change for rectangular section reinforced concrete bridge pier under different axial compression ratio and different forces of horizontal earthquake action, which is verified according to the test result. As a result, a stiffness reduction factor is proposed to consider nonlinear characteristics of reinforced concrete bridge pier.
