Abstract: A statistical investigation on geometrical imperfections and fabrication tolerances of plate elements as well as the reducing effect on their ultimate strength in steel girder bridges fabricated in Japan are described. ...

Abstract: This paper is concerned with a statistical study on initial deflection of plate members, such as stiffened plates and diaphragms, in steel girder bridges recently fabricated in Japan, in order to provide some information ...

Abstract: This paper summarizes the reduced ultimate strength of the compression flange of plate girders containing initial deflection. The major findings are as follows: There is no interrelation between the maximum initial deflection ...

Abstract: Effective slenderness ratios for inelastic lateral buckling of throughtype arches are determined by utilizing an analogy between an arch and a column. A designer can use the effective slenderness ratio to obtain an ultimate ...

Abstract: This paper presents a statistical study on the actual imperfections and their relations to the strength of webplates and their stiffeners of bridge superstructures. The field measurements, data acquisition, and processing ...

Abstract: In plate girders built up by welding, residual stresses and initial deflections inevitably remain in both flanges and web. Taking into account this fact, a numerical plastic analysis was carried out by the incremental ...
