Abstract
A reinforced concrete slab is one of the most important structural elements of a building. There are different types of slabs, such as one-way or two-way solid slab, flat plate, one-way or two-way ribbed slab, etc. The economy and safety of building depend on choosing the right kind of slab and implementing the code requirements. In the absence of a national design code in Libya, any of the international codes such as ACI 318-11, BS 8110-97, or Eurocode 2 can be used to design a slab. In this paper, a comparative study of different types of slabs is conducted to find the most suitable or optimal solution using different codes. For this purpose, the software “Autodesk Robot Structural Analysis” is used. Four parameters are considered for comparison, and they are: deflection, concrete volume, weight of steel reinforcement used, and cost. The software’s special feature for quantity surveying is used to determine the concrete volume and weight of steel reinforcement. After design and comparison, it is found that the ACI code requires more reinforcement and concrete, which leads to a greater total price, but it gives less deflection. On the other hand, BS code gives less total price but more deflection.
