THE FLEXURAL BEHAVIOR OF HOLLOW CORE CONCRETE SLABS WITH DIFFERENT SHAPE

Hollow slabs are of reinforced concrete in which voids allow the to be reduced size. This type slab results raw materials Consumption and increased insulating properties achieve sustainability goals. paper reported an experimental research program focused on study bending behaviour elements hollow normal-strength concrete. Three models one-way were cast, It had dimensions 1020 mm length, 420 width, 100 thickness. The first model did not contain holes (solid) second contained five circler opening with a 50 diameter, while third square 44 dimension, where area same despite difference shape opening. showed that bearing capacity circular core is higher by 12% compared according both made decrease load 11% 25% when solid slab. has lower deflection value two whose weight 23%
