The use of load limiters on shores to improve the construction process of RC buildings

What is it about?

This paper analyses the redistribution of maximum loads using a system of load limiters on shores in which the limiters yield at a given load and thus reduce the maximum load absorbed by the shores. For this analysis a finite element modelling (FEM) of an experimental building was developed in which load limiters had been fitted to the shores to restrict their maximum load to a given value. This was designed to: (a) optimise slab construction costs by using shores of lower load-bearing capacities, (b) improve safety during the construction of consecutive concrete slab floors by reducing maximum loads and redistributing loads amongst the shores; and (c) increase structural efficiency by more efficient use of the materials employed due to load redistribution. It has been estimated that using load limiters in this way can reduce total shoring costs in a building project by between 30% and 40%.

Why is it important?

The idea of limiting loads on shores is a novel concept that aims to redistribute maximum loads by means of the plastic deformation of the limiters in order to control the load assumed by individual shores. This technique has beneficial effects on three of the most important aspects of constructing reinforced concrete slab floors that have already been subjected to a large number of studies, i.e. it optimises slab construction costs, improves safety in concrete slab construction and achieves higher structural efficiency.
