Numerical Simulation Research Of Damaged Bridge Pier Capacity

Increasing with the service time of large number of bridge, assessing and reinforcing of bridge became increasingly to be important part of maintaining of existing bridge. So, we need to evaluate the existing bridges periodical and perennial which are in the service and maintain the defect of them in time to enhance life-span and performance at the same time of building new bridges, Systemic and embedded academic research and technical exploitation which aim at evaluation reinforcement technique of national existing bridges have important applied value.According to various forms and extents of pier damage, this thesis has numerically analyzed the damaged pier model with the finite element software ANSYS. In this thesis, all the element models and methods of solution and the key parameters of solution which involved in the pier model have been introduced in detail. In addition, onthe basis of the analysis of structure materials, this paper has selected rational material constitutional relationship. The input work is completed by use of the procedures and the user subroutines provided by ANSYS. Through calculate capacity of different forms injury pier, analysis of the calculation results, which can explain the impact of different forms injury to pier capacity.The main method of reinforcement pier is use different materials in the external of damaged pier, but in most of case, the damaged pier can't be repaired in time, so in this paper, we can solute such questions through architectonics so that the bridge pier capacity can keep from loss largely.In this paper, we mainly appraisal damaged bridge pier capacity with nonlinear theory and talking about reinforcement methods.
