Abstract: With the development of infrastructure in city, more and more bridges with wide-span ration have been constructed as well. As the lateral distribution is much more apparent in this kind of bridges compared with the common ones, there would be some deviations in calculating live load effect of bridges if they were simulated in by traditional bridge modeling. Based on the analysis of simple supported hollow slab with a 2.3 width-span ration by structural plane and space loading modeling, a comparison of deformation and stress of the bridges between the calculation value and actual surveying value after loading was made to provide a practical reference for engineering works.

Key words: simple supported void slab, coefficient of lateral distribution, grillage method, static loading test
