The Study on Mechanical Performance of New Composite Steel-Truss Travelling Bridge Structure
TLDR
Based on the bearing features of travelling bridge structure, as well as features of steel-truss beam and steel box beam, a new composite structure which is named as steel truss-steel truss box beam was put forward in this article.Abstract:
As for structural beam of travelling bridge under reciprocate loads, at the bearing there will be a large change in stress of structure, while at the ends and midspan, the change of stress of structure will be simple In this paper, based on the bearing features of travelling bridge structure, as well as features of steel-truss beam and steel box beam, a new composite structure, which is named as steel truss-steel truss box beam, is put forward This new structure adopts steel box beam with truss inside at the bearings, and adopts steel truss beam at the midspan Based on a certain engineering project, combined with ANSYS, according to a serious of sizes and structure styles, work of modeling, analysing and optimizing has been done in this paper As calculating results showed, steel truss-steel truss box beam not only has higher bearing capacity, structural bearing capacity and a better wholeness, but also has a lower steel usage, which can provide references for similar composite structures' research in futureread more

Approximate Solution to Through Steel-truss Composite Beams under the Action of Double-track Symmetry Loads
TL;DR: In this article, the displacement and stresses of a simple-support through steeltruss composite beam model with four spaces were calculated by means of the proposed method and the results showed the exactness of this paper's formulae by comparing their proposed method solutions to the test results.

Performance of Edge-Loaded Cold-Formed Steel Built-Up Box Beams
TL;DR: In this article, the flexural performance of box beams under eccentric edge loading is discussed and the combined effects of edge loading and the connection of the two primary box beam components (toe-to-toe joists), by top and bottom track members, may reduce the overall strength of the box beam.
