DEFLECTION CONTROL DESIGN FOR REINFORCED CONCRETE AND PARTIALLY PRESTRESSED CONCRETE LARGER SPAN SLABS

Katsuya Okada, Haruhiko Okamoto, Yosihiro OTA, Tatsuo Okamoto

Abstract

The needs of larger span reinforced concrete slabs such as long life housing with a support and infill system are increasing. For larger span slabs the deflection control design is requested because of serviceability problem resulting for excessive deflection. The aim of this paper is to propose the design method of deflection control by applying author's calculation method of minimum slab thickness and of long term deflection of reinforced concrete and partially prestressed concrete slabs.
