Seismic safety evaluation and seismic design of Ningjiang Songhua River bridge
摘要
Abstract
Ningjiang Songhua River bridge locates in a seismic intensity Ⅶ zone in Songyuan City, Jilin Province. The structure of main bridge is with four towers and single cable plane cable-stayed bridge with low towers structure. In the process of seismic design, El and E2 two levels of fortification are adopted. The earthquake recurrence interval of El and E2 is set as 100 years and 2 000 years, respectively. The multi mode response spectrum method for El earthquake, and the nonlinear time-history method for E2 earthquake are employed in seismic response analysis. Our results provide a reference for the design of similar project.关键词
