摘要

针对混合试验中的数值积分方法进行了研究，提出基于Newmark-β法的预测-几何修正算法（P-GC）。算法采用过程刚度进行子结构边界位移预测，通过几何修正方法找回所丢失的预测位移增量值。依托P-GC算法开发多跨连续梁桥多子结构协同混合试验系统。最后通过某实际多跨连续梁桥进行数值模拟试验验证，结果表明基于P-GC算法的多子结构协同混合试验方法能够有效的模拟桥梁结构的地震响应以及多个子结构的非线性行为。

Abstract

Based on Newmark-β method, a predict-geometric correct algorithm (P-GC) was proposed to be taken as a numerical integration method for multi-substructure hybrid tests.With this method, the process stiffness was adopted to predict boundary displacements of substructures, and the geometric correct method was used to retrieve the lost predictive displacement increment of substructures.Based on the P-GC algorithm, a multi-substructure collaborative hybrid test system was developed for multi-span continuous girder bridges.Finally, numerical simulation tests were conducted for a certain actual multi-span continuous girder bridge.The results showed that the multi-substructure collaborative hybrid test method based on the P-GC algorithm can be used to effectively simulate seismic responses of the girder bridge structure and its multiple substructures’ nonlinear behaviors.
