Abstract:
The purpose of this research is to achieve a more comprehensive understanding of load distribution in reinforced concrete structures during construction. Efforts have been made to measure and analyze loads, material properties, internal forces in shores and slabs, and displacements of structural members during the construction of a reinforced concrete slab-and-beam structure. Some phenomena and results, which have not been reported previously, were observed. Through the process and analysis of the measured data, the characteristics of load transmission (distribution) in the time dependent structure have been obtained. It has been found that the newly cast slab will gradually carry some of its own weight during its curing process. This then causes the construction loads to redistribute between the slab and other parts of the time-dependent structure.
