Influence of Diaphragm Plates Arrangement on Torsional Behavior of Skew Hollow Slabs
摘要
Abstract
The goal of this paper is to assess the torsional behavior of the skew hollow slab bridge utilizing polystyrene foam inner formwork with diaphragm plates. The spalial finite element method was established using the solid element. Two diaphragm plates were arranged at the end and the middle sections of the slab, respectively. The influence of diaphragm plates arrangement on torsional behavior of skew hullow slabs can be obtained through the comparisons of the torsion angles in l/8 section, l/4 section, 3l/8 section and mid-span section as well as vertical displacement nephograms in l/4 section. The results show that end disphragm plate can effectively improve the torsional behaviors of the skew hollow slab. The middle diaphragm plate associated with the end diaphragm plate can reduce the torsional deformation in mid-span section, but have slight effect on the other sections.关键词
