A New Strategy to Assess the Seismic Energy Dissipation Safety of Reinforced Concrete Bridge Piers
Full Paper(PDF, 358KB)
In this study, a new strategy to assess the seismic energy dissipation safety of reinforced concrete bridge pier was proposed. Based on dynamic energy equation of multi-degree structures and inverse deduction of Park-Ang damage model under given displacement and damage controlling conditions, a real highway circular bridge pier was analyzed to show the feasibility of present theory and method by use of popular finite element software. The results show that the real ability of energy dissipation of the reinforced concrete circular bridge pier can be calculated under given displacement and damage controlling conditions and then the safety factor can be obtained subsequently in varied earthquake waves corresponding to different seismic classes and damage index where the complex non-linear calculation process related to the restoring force model of the structure becomes unnecessary. The strategy involved in this paper is very simple and easy to be realized which can make full use of the advantage of finite element software and may provide effective means for the seismic assessment of existing or proposed reinforced concrete bridge piers.
