ALSINA.<br/>This paper presents a new simplified procedure for estimating loads on slabs and shoring during the construction of multistorey buildings. The new procedure takes into account the actual stiffness of the shoring and for the first time includes the hypothesis that the average deformation of the shores coincides with that of the slabs they support. The procedure was verified by an experimental study that consisted of the construction of a full-scale three-storey building using a shoring-clearing-striking (SCS) process. Further verification was provided by the results of a finite element model of the same building. The results of the new process were then compared to those obtained from the proposals of other authors who had also considered the real stiffness of the shoring. © 2011 Elsevier Ltd.<br/>
