Abstract
In this paper, a load transfer mechanise of compression joint, which is a new joint system of precast prestressed concrete (PPC) slab pavements used in airpoit aprons, is described. At the compression joint, PPC slabs are connected with jointing sections using PC stand installed in slabs at acertain interval so that the shearing forte and bending moment are transferred between slabs. To analyze mechanical behaviors of PPC slab pavements, 3D FEM was used; the former is modeled as vertical springs and the latter is modeled as horizontal springs. Both the validity of the model and their mechanical properties are verified through loading tests of an experimental pavement.
