摘要：
By establishment of ANSYS model and combining with the characteristics of temperature field, the research is carried out on temperature field through Pi-beam bridge, it shows through theoretical analysis that temperature field of the plates inside and outside surface is in the time lag relationship, and the numerical analysis shows that the change of the thickness of the roof and side ribs is limited to the temperature of the outer surface of the plate, and thermophysical properties of concrete is little effect on temperature field of the concrete beam, and the speed of wind has less impact on temperature field of the concrete beam. Comparing the theoretical data with the experimental data shows that the distribution of the pi-beam temperature field is reasonable, indicating the validity and effectiveness of the analysis.
