Nonlinear Analysis of Curved Prestressed Concrete Cable-Stayed Bridge due to Large Deflection

대변위를 고려한 곡선 프리스트레스트 콘크리트 사장교의 비선형 해석

A study for the nonlinear analysis of segmentally erected curved PSC(prestressed concrete) cable-stayed bridge considering the effects due to large deflections is presented. Various case studies regarding the effects of the material nonlinearities and the geometric nonlinearities on the behavior of segmentally erected curved PSC cable-stayed bridge are conducted. The numerical results on the bridge which has relatively low stress profile through the bridge deck section like the example herein show that the geometric nonlinearities has more significant effects on the structural behavior than the material nonlinearities.
