Mechanical Analysis of Prestressed Concrete Partially Cable-Stayed Bridge with Corrugated Steel Webs

The structure of C-bridge is prestressed concrete partially cable-stayed bridge with corrugated steel webs with a main span of 188m, and the span arrangement is 58m+118m+188m+108m, and the form of box-girder section is one-box four-rooms with inclined webs. In this paper, the finite element method is used to model C-bridge's structure and do analysis of construction stage and completed bridge stage, and the analysis is checked with the current corresponding regulatory of bridge design and construction. Checking results show that under the existing highway-I level loads, the main beam's carrying capacity, stress and crack resistance meet the regulatory requirements. Meanwhile, the adjustment process of cables for the partially cable-stayed bridge is narrated. The checking process also reflects the mechanical properties of corrugated steel webs.
