Temperature effects on load transmission between slabs and shores

What is it about?

This paper analyses the influence of temperature changes on load transmission between floor slabs and shores during the in situ casting of concrete slabs by the shoring-clearing-striking method. Therefore several experimental studies were carried out which measured both the internal temperature evolution of the slabs and the loads on the shores. With the results of these studies, a Finite Element Model (FEM) of an experimental structure was then developed. In both the FEM and the experimental studies the same behaviour was observed regarding changes in temperature.

Why is it important?

The effect of ambient temperature changes on load distribution between shores and floor slabs has received little attention to date, even though certain authors have emphasized its importance. Therefore, the need to know how the ambient temperature affects the different elements of the structure and to study its influence on the variation of the load on shores was raised.
