| Abstract |
Recently, the interest in precast voided slab system for buildings is growing up according to the demand for high quality control and the increase in slab thickness A hollow slab system is widely known as one of the effective slab system which can reduce self-weight of slab However, in case of conventional precast voided slabs, It is uncertain to apply these slab system to two-way slabs because It have a rectangular shaped void-former In this study, I-slab system that applies plate type and octagonal pillar type void-former on slim precast slab deck is developed, and then flexural capacity of the I-slab system Is evaluated by 4-pointed banding test In addition, flexural capacities of I-slab system along the longitudinal and transverse axis are compared to verify the applicability of I-slab system to two-way slabs Test results showed that I-slab had enough flexural strength and ductility for slab member In addition, I-slab system Is found to be sufficiently possible to apply on two-way slabs |
