Abstract
The selection of damping coefficient has a great influence on the dynamic response analysis of high⁃pile wharf under the action of seismic field. In this paper, the damping self⁃modification method of dynamic numeri⁃cal simulation model under the action of seismic field was put forward for the first time. Adopting the constitutive model of cracked concrete, the dynamic response and cracking process of high⁃pile wharf under the action of seis⁃mic field were simulated. Comparing the numerical simulation results with the calculation value based on the cur⁃rent codes, the damping coefficient of pile⁃soil⁃integrated structural model was determined effectively. It can be con⁃cluded from the research that the self⁃modification method of damping coefficient can make the dynamic response simulation of high⁃pile wharf under the action of seismic field more reasonable and accurate rather than just relying on the empirical parameters.关键词
