Thirdly , in this thesis , the influence of concrete creep to the behaviors especially to the nonlinear behaviors of reinforced - concrete box girder has also been studied and the effect of creep on internal force , deformation , ultimate load capacity and shear lag of reinforced concrete box - girder has been included , and the parameter such as loading duration , age of concrete and sustained load are considered

In this paper , the golden phoenix bridge over meixi river in shantou - a long span curved box - girder bridge in xigang viaduct project - is taken as computing and analysing model . by using the spacial analysis software asbest ' 98 , its mechanic characteristic such as stress , shear lag and displacement is analyzed

Based on the research of influenced parameters on constant and varying depth solid web box girder before , the shear lag aroused by the parameters including width - span ratio , outstanding flange on base slab and the position of the tendons are further studied . the investigation show that shear lag values diminish along with the decease of width - span ratio and the departure from the symmetrical axis of anchor position , but outstanding flange is contrary to the former

This paper argues that it is the adoption of the new anti - literal force members that results in the specific behaviors of the system . by studying the shear lag phenomena of short leg walls , the author wants to show a peculiar aspect of this new structure system . after analyzing the working conditions of the short leg walls in the real structures , the paper deems that the plane - shell element can be used in establishing the finite element model of the short leg walls
