钢板−CRRPC−TPO复合梁弯拉受力非线性分析
Nonlinear analysis of flexural performances on composite beam STEEL?CRRPC?TPO
摘要
Abstract
To solve major problems for long-span steel bridge such as fatigue cracking and damage on pavement, a STEEL?CRRPC?TPO composite deck paving system was presented. Based on the nonlinear stress?strain relations of steel, CRRPC and TPO, a whole process of bending simulation was made, and the cracking point, yield point of the steel and the failure point were obtained for the composite beam of the new paving system. The results show that the theoretical analysis can reflect the loading features and the deformation performances of the STEEL?CRRPC?TPO composite deck paving system. The errors of load at feature points are 3.2%?3.9%, and the errors of deflections are 5.7%?8.7%.The cracking load and failure load of the simulations are lower than those of the experiments, which means that the engineering design using the simulation process has higher security.关键词
