Studi Eksperimental Jumlah Segmen terhadap Kekuatan dan Kekakuan Pelat Lantai Beton Segmental

[Title: Experimental Study to Investigate the Effect of Number of Segments on Strength and Stiffness of Segmental Precast Concrete Slab] small-sized segmental concrete blocks into a concrete structure. The objectives of this study are to examine the effect of the number of segments on the behavior and strength of the segmental concrete slab, in terms of load capacity, maximum deflection, and stiffness of segmental concrete slab. The specimens used concrete grade f’c 25 MPa with tension bar 2-D10. The dimension of specimen were 2 meter length and 25 cm width. The specimen were varied into 5 conditions, namely monolithical slab without segmental blocks specimens, one segment with concrete topping, two-segment specimens, four-segment specimens, and eight-segment specimens. The experimental tests were carried out using a one-way flexural test method with two points loading. Research results show that the load capacity, the stiffness, and the ductility of the segmental slabs decrease with the increase of segment numbers. The reduction of ultimate load percentage of segmental concrete slab with n number of segment can be estimated using equation Pn = 100.e-0,111.n
