19 Computer Application in Civil Engineering: Nonlinear Time-History Response Analysis of Viaduct Bridge Based on TDAP III
Download citation file:
In civil engineering, the computer has been widely applied and developed as the advantages of speed and high accuracy, in the last 20 years. This paper describes nonlinear time-history response analysis of bridge structure under strength ground motion. Special seismic analysis program-TDAPIII (Time domain 3-dimensional dynamic Analysis Program) is used in this analysis. Firstly, the direct integration method for solving dynamic problems and the calculation method of fiber element are introduced in this program. Secondly, a five-span continuous viaduct bridge including the foundation, rubber bearing, and superstructure and RC piers is modeled and the dynamic response analysis of model is...
