Beffeting Analysis of Long Span Cable-stayed Bridge using PCCAP
PCCAP을 이용한 장대 사장교의 버페팅 해석
Abstract
In this study, a time domain analysis is presented for investigation on the buffeting response of cable-stayed bridge during both erection and completion stages. The main span length and width of deck are 520 m and 15.1m, each. Since the ratio of span over width is 34.44, aerodynamic stability of the bridge during erection is expected to dominate the safety of the bridge in construction stage. Several conclusions regarding different construction stages and temporary wind cables are obtained.
