Abstract
By means of increasing specified strength of concrete, the setting period of slab form can be reduced. When the form of slab is set, construction stage can be classified as follows; the allowable period of upper story work and the setting period of form and support of slab. Six full size scaled specimens with variables such as concrete strength and loading time are fabricated. Structural behavior and serviceability is examined at each construction stage. Test results show that the form of slab can be removed 2 days early without any damage of serviceability in case of increasing of concrete strength. This results were applied to a 15 story RC apartment, which were accomplished construction sequence analysis. As a results, the models are satisfied with structural safety, serviceability. Decrement of indirect cost showed greatly more relatively than increment of direct cost as result that achieve construction cost analysis of in case shortened 30 day's term of work at removal of forms early stage by concrete intensity promotion.
