Abstract
The nonlinear temperature gradient of element section is equivalent transformed into a combination of uniform and linear temperature gradients in the research,so that the nonlinear temperature gradient effect of element section can be calcu-lated.Based on influence lines,the most unfavorable position of live load is distributed manually,so that the concurrent reac-tion force of moving load can be calculated.Then SAP2000 software can achieve the function of anti-overturning checking cal-culation of bridge.Taking the 2 × 16 m ramp curved bridge as an example,the structural gravity,foundation displacement,moving load,wind load and temperature gradient are calculated.Then,according to relevant specifications,SAP2000 software is used to check the lateral anti-overturning of the bridge,and Dr.Bridge software and MIDAS software are used to verify.关键词
