Study On Continuously Supported Concrete Slab-on-grade

This thesis deals with the study of continuously supported slabs-on-grade for residentialrnbuildings supported by soil. If we consider our country, Ethiopia, due to mass construction ofrnresidential buildings, the thickness of slab and area of reinforcement of the ground floor slab isrnnot from the result of detail structural design, as a result the slab thickness and reinforcementrnbars are not uniform for same kind of slab on grade. In effect, if detail design is carried out forrneach slab-on-grade, it can be minimized to optimum design, which will have a significantrndifference to the total cost of the building according to the project. rnTherefore, this thesis will help to study a continuously supported concrete floor slab at grade.rnConcrete and reinforcement are the two primary expenses in cast-in-place concrete floorrnconstruction. Hence, by minimizing the thickness and area of reinforcement of the ground floorrnslab, the cost of construction can be significantly minimized. To emphasize and verify thisrnstudy, a field test is conducted on four samples at Bole-Ayat Condominium Site. The resultrnconfirmed that by minimizing ground floor slab thickness and area of reinforcement, the costrnof the construction can be significantly reduced.
