Abstract:In the present age of rapid construction of high-rise reinforced concrete buildings, documented investigations and recent analytical studies have shown that construction loads on a supporting system, including slabs, shores, and reshores may exceed appreciably their load-carrying capacity, and therefore contribute to a significant portion of the disasters of reinforced concrete buildings during construction. The construction process of a concrete building is time-dependent. It is difficult and complicated to determine the load and deformation values accurately in the structure at every stage of construction. A simplified method developed by Grundy and Kabaila is introduced whereby the relationship between the loads imposed on the supporting system and the basic parameters, including the number of shored floors, the number of reshored floors, the time parameters, and the concrete types is then analyzed. Based on this information, simple rules for an optimal choice of shoring and reshoring are proposed.
