Abstract

This paper presents ultimate strength of steel cable-stayed bridges with short tower which are suitable for constructing at the site near an airport in the urban area. The cable-stayed bridges with center span length of both 400-meter and 600-meter whose tower heights were 1/10 and 1/5 of the center span length were designed. Using the designed model, we studied elasto-plastic behavior and ultimate strength of both cable-stayed bridges.<br>From this comparative study, it is presented, even if the height of tower reduced to about half of economical height (1/5 of center span length), that the cable-stayed bridges have ultimate load factor βu of 2.07～2.20 for 400m and 600m-spanned models and are expected to be competitive.
