Abstract/Summary:
In recent years, the box girder with corrugated steel webs is developing rapidly in China as a new bridge structure, and the number of which has reached more than 30. However, the research on the transverse internal force is less or not formed the theory or specification system. In this paper, in the foundation of the predecessors’ research, the transverse internal force distribution of the multi-cells wide single box with corrugated steel webs had been systematically studied through experimental study and finite element analysis. Under the commission of National Natural Science Foundation of China(51308053), transverse Internal force of wide corrugated steel webs in box beam were studied. The main works involved in this research are as follows.Firstly, on the contrast to ANSYS, the distribution of transverse internal force of single, double & three rooms in single box scale test model had been done in different load conditions.Secondly, research of the thickness & wave shape of corrugated steel webs on the influence of the bending and deformation had been studied, doing further study of the influence parameters.Relevant suggestions had been put forward based on the influence of load position on the muliti-cells in single box.Thirdly, based on the results between the standard and ANSYS under the different vertical & horizontal span, the distribution rule of transverse internal force had been summarized of the single and multi section in one room.Finaly, aiming at the differences between the standard and the result of ANSYS, this paper puted forward a method for the correction of the effective distribution width, which had presented a formulas.
