On-site measurement of load distribution in reinforced concrete buildings during construction

The purpose of this research is to achieve a more comprehensive understandi ng of load distribution in reinforced concrete structures during constructi on. Efforts have been made to measure and analyze loads, material propertie s, internal forces in shores and slabs, and displacements of structural mem bers during the construction of a reinforced concrete slab-and-beam structu re. Some phenomena and results, which have not been reported previously wer e observed. Through the process and analysis of the measured data, the char acteristics of load transmission (distribution) in the time-dependent struc ture have been obtained. It has been found that the newly cast slab will gr adually carry some of its own weight during its curing process. This then c auses the construction loads to redistribute between the slab and other par ts of the time-dependent structure.
