Vertical Connector Performance of Modular Roadway Slab

Abstract:

This study investigated vertical connector performance of modular roadway slab. A modular roadway utilizes precast members of slabs and crossbeams under the slabs, and the connection between them is critical. The vertical connector has to resist horizontal loads and allow the thermal movements. In the preliminary study, two boundary conditions were investigated to identify the better vertical joint functionality. Based on the results, detailed analysis models were developed and displacements and internal forces of the vertical connector were investigated. The analysis results showed that for the given modular slab and developed vertical connector, the vertical connector provides better stability and functionality but required 80 kN of horizontal shear forces.
