Paper Title:
Research on Deflection and Stress of CRCP under Concentrated Vehicle Load over Hollow Base
  Abstract

Based on the small deflection theory of elastic thin plate and the equivalence principle of deflection and stress, the concentrated vehicle load which acts on the CRCP is translated into the equivalent half-wave sine load by Fourier transform. On the basis of this transform, the deflection and stress formulas are put forward when CRCP is subjected to a concentrated vehicle load with hollow foundation. The following results are obtained from the analysis. The maximal deflection is proportional to the concentrated vehicle load and slab width, and inversely proportional to the lateral bending stiffness and slab thickness. The slab width and thickness have a significant influence on the maximal deflection. The maximal stress is proportional to the concentrated vehicle load and slab width as well as inversely proportional to the slab thickness. The influence of slab thickness is significant to the maximal stress. In conclusion, increasing the slab thickness is the preferential choice to reduce the maximal deflection and stress.
