Comparsion Between HoHow Block Slabs and Flat Slabs in Design and Cost

Abstract

In this thesis, one of structural member which called slabs are studied as general and in particular one of this types hollow block slab as structural system. This structural system is a new method of construction for flooring system is used in Sudan, and this research is covering this type which is included the analysis and design of hollow block slab using different provisions codes: Egyptian cod (EPC 203-2007), American code (ACI 318-2005) and British code (BS 8110-1997).In additional to reinforcement detailing and construction method. The results of analysis and design by codes are compared to find the code designable achieving economical and safety. The economical and safety code is used to analysis and design tow floors system; flat slab and hollow block slab and compare results to find the best system and lesser cost. This thesis is concluded to that hollow block slab is suitable system because the lowest cost and other features make it suitable structural system for hot places like Sudan.
