Abstract：Based on the ultra-precision electronic factory of Tianma Optoelectronics Limited Company of Xiamen City，F(xiàn)ujian Province，ABAQUS finite element software was used to simulate 3-dimensional（3D） model of the beam-slab structure，the simulation data and the monitoring data from the construction site were compared.The influence of temperature action on the ultra-long structure with large-span slab was studied from the slab thickness，reinforcement ratioes，and concrete strength grades，and parameter value suggestions were proposed for actual engineering. The study shows that the influence of temperature action on the slab stres is positively correlated. Under temperature action，the reinforcement ratioes of the slab have a significant impact on the stress and deformation of the floor slab，while the strength grades of concrete only havea significant impact on the deformation of the floor slab，and the the slab thickness has a certain impact on the stress of the floor slab.The temperature difference has a certain impact on the deformation of the central floor.
