WebFeb 6, 2011 · A simplified stress analysis procedure was proposed and implemented in a user-friendly computer program (ILLISTRS) to facilitate instant stress estimations and practical trial applications.Key... WebJun 13, 2024 · This means the moisture in drying concrete is going to leave essentially only from the top, causing the slab to shrink faster (concrete shrinks as it dries) on the top than the bottom, and curl upward in the process. Differential drying can be exacerbated by adverse ambient conditions.

WebApr 26, 2012 · This study deals with the finite element (FE) analysis of curling stresses and field measurement of curling of a newly built jointed plain concrete pavement. The FE … WebIn Portland cement concrete (PCC) pavements, tie bars are commonly used at longitudinal construction joints (LCJs) to prevent the lanes from separating. Meanwhile, the increase in multiple lanes due to greater traffic volumes has raised concerns about potential longitudinal cracking; this has led to the use of dowel bars instead of tie bars at LCJs. However, there … WebApr 19, 2024 · Curling generally results from the temperature differential across the concrete slab thickness and may induce undue stresses in a newly placed slab.
