预制拼装桥墩滞回分析模型和损伤评估研究
Hysteretic Analysis Model and Damage Assessment of Precast Assembly Bridge Piers
摘要
Abstract
To study the seismic resistance performance and the earthquake damage characteristics of prestress precast assembly bridge piers,Bouc-Wen-Baber-Noori model was used to simulate the pseudo-static test of the precast assembly bridge piers.The calculation codes were programmed on the basis of Simulink module of Matlab software,and the key parameters of the hysteresis model were determined according to the test results.Park-Ang damage model was combined with the modified one to evaluate the damage degree of the bridge piers.The researches show that the Matlab-based calculation results are in good agreement with the test results,that is,the damage assessment of the bridge piers is reliable,the hysteresis model and damage analysis model can apply to the anti-seismic calculation and assessment of the precast assembly bridge piers.关键词
