Both Truss Arch Structure Analysis And Evaluation Research

This text introduces the structure and makes up, the constructs characteristic, the mechanics characteristic,the pluses and minuses of the trussed arched bridge, steppingthe foot-path to already having is 30 meters of trussed arched bridges——YanHeQiao,carrying on comprehensive analysis and research to this bridge on the basis of loading and testing.Utilize level pole department's mode , finite element of procedure set up the computational analysis model of internal force, carry on test with operating mode in internal force and deflection calculate, which compared with the test data, evaluation result of drawing static testing; Utilize above-mentioned models to calculate out the control internal force, join the rib to intensity checking computations.Utilize the entity's unit of the large-scale finite element procedure to set up the space model of real bridge , carry on the dynamics characteristic to calculate, and analyse to natural frequency and shaking type, compare the result of dynamics result of analyse with the result of dynamics result of test, drawing the conclusion of dynamics testing. On the basis of the dynamics characteristic is analysed, carry on the time history analysis of the moving automobile loading and the earthquake loading, draw the relevant conclusions of time history analysis.Evaluate from different angles through the above static test evaluate, dynamics test evaluate, intensity checking computations, dynamics characteristic analysis, time history analysis of the moving automobile loading and the earthquake loading, draw the corresponding conclusion of the trussed arched bridge of the same type, put forward the relevant suggestions.
