Abstract
Through trial designs of cable-stayed bridges with main-span length of 1400m, steel weight and construction cost of the bridges made of different steels named as Q345, Q420, HPS70W and HPS100W of which their yield points are 345, 420, 485 and 690 MPa, respectively, were investigated. The results indicate that the steel weight and construction cost can be reduced obviously with the increase of steel strength, although the design stresses of some plates of the box girder are not governed by material strength due to the influence of the stability of stiffened plates and the limitation of minimum plate thickness.
