Title: Simplified Methods for Crack Risk Analyses of Early Age Concrete Part 1: Development of Equivalent Restraint Method
Author(s): Majid Al-Gburi, Jan –Erik Jonasson, Martin Nilsson, Hans Hedlund, Anders Hösthagen
Appears on pages(s): 17-38
Keywords: Local restraint methods, compensation plane method, equivalent restraint method, crack risk, early age concrete.
Abstract:The present study deals with both the compensation plane method, CPM, and local restraint method, LRM, as alternative methods studying crack risks for early age concrete. It is shown that CPM can be used both for cooling and heating, but basic LRM cannot be applied to heating. This paper presents an improved equivalent restraint method, ERM, which easily can be applied both for usage of heating and cooling for general structures. Restraint curves are given for two different infrastructures, one founded on frictional materials and another on rock. Such curves might be directly applied in design using LRM and ERM.
