thermostressed state

Термонапружений стан монолітної попередньо напруженої естакади

This article describes the problem of influence heat during hydration reaction in an array of monolithic reinforce concrete prestressed overpass span on its mode of deformation. The goal is to determine the causes of cracking in the construction span, improve its placement and recommendations to prevent cracking in similar processes. During examination of the object of study – flyover in Kiev spans were found with crack opening width 0,15 mm, which emerged during its construction.
