两等跨连续梁的模态分析试验
Experiment of modal analysis to two-span continuous beams
摘要
Abstract
A modal analysis test of two-span continuous beams has been carried out with the DASPsoftware in this paper.The first two order frequency and damp ratio of these continuous beams are obtained.Simultaneously,the two-span continuous beams model has been built by the Midas Civil software,and the algorithm has been performed.Then,a comparison has been made by the algorithm result and modal analysis result.The results show that： the test result is consistent with the finite element analysis result,with the frequency deviation in 5%.It is feasible to get modal parameters of the continuous beams by modal analysis experiment.关键词
