Flexural Behaviour of RCC Beams

Concrete is the material which is rapidly used in various conditions to sustain the compression loads and the corresponding bending and shear stress due to the applied compressive loads. The major drawback in concrete is that it is poor in tension though it is very efficient in compression. Hence to overcome this major drawback the concrete must be reinforced such that to make a homogeneous substance which can sustain both tension and compression. Steel is the material use as reinforcement for concrete. The stress strain behaviour for both concrete and steel are mostly similar. Hence in the combination of both that is in reinforced cement concrete the maximum stress point within the elastic will reach simultaneously. Reinforce cement concrete is a general material which is widely used for various types of constructions and structural elements. For the efficient use of RCC it is necessary to know the properties and the behaviour of RCC elements under various constrains. To estimate and analyse the basic properties and behaviour of RCC an experimental study is needed. In the present study an experiment in which flexural behaviour of RCC under various constrains was the major criteria. For the experimental analysis simply supported beams of undereinforced, balanced and over reinforced sections are considered. When the beam is simply supported and is subjected to some external loading the corresponding deflections are examined such that the flexural behaviour of the RCC beams of under reinforce, balanced and over reinforced sections analysed. In order to study the flexural behaviour of any material one had need some basic constant conditions as their limitations. In the present study stress-strain behaviour of Concrete and steel are taken as a base and the flexural behaviour of the material in various fibres.
