Abstract:
Closure strips are temporary gaps in reinforced concrete floor slabs. They are provided to allow sections on either side to undergo shrinkage independently; however, only limited guidance is available for their design. This article summarizes currently available design approaches, presents a case study of closure strip monitoring, and compares the obtained field data with predictions from the available design approaches.
