Abstract
Reinforced Concrete (RC) slabs are used in roofs, floors and walls of
buildings and in the bridges as decks. The floor system takes various forms; in situ ribbed slab, flat slab, solid slab or pre-cast units. They may be supported on beams (steel beams or RC beams), walls or directly on the columns. If the restrained slab deflects under the applied loads, their edges try to move outwards. In the case of solid slab system, the supporting beams provide a lateral restraint to the outward movement. Also in-plane compressive or tensile forces are certainly introduced across cross section of the slab. These forces act
on the edge beams and they cause lateral outwards movement for the beams. These forces are dependent on the flexural rigidities of the edge beams.
The main objective of this research is to study the ultimate load and flexural
behaviour of two-way reinforced concrete solid slabs with different dimensions of the edge beams (the beams are different in the reinforcement and
dimensions) and in the case of without edge beams.
An experimental program was designed in the current work to examine the structural behavior of reinforced concrete solid slabs under uniform load up to failure. The experimental program comprised casting and testing of nine solid slabs with different supporting beams and one solid slab is cast and tested without supporting reinforced concrete beams. The supports are reinforced concrete beams with different dimensions and reinforcements. The flexural performances of the all tested specimens in terms of strength, ductility, cracking behavior and energy absorption were investigated.
All the tested specimens were simulated using SAP and SAFE programs in
addition to some international building of codes. The results of the
experimental tests concluded that the specimen based on high-inertia edge
beams gives the highest first crack load and ultimate load. Additionally the specimen based on beams with high reinforcement gives the highest first crack load and ultimate load. On the other hand the specimen based on low-inertia beams gives the lowest first crack load and ultimate load.
