(57) Weight is a highly effective factor in the design of structures with different occupancies, particularly in cases where it increases the gravity and seismic forces acting on the structure. In applications, thickness of the beams and slabs with large spacing must be increased, leading to a corresponding increase in structural weight. Different methods including the hollow-core and the waffle methods have been proposed to reduce ceiling weight in structures. The proposed method in this paper would not only provide a greater ceiling...
