Reinforced Beam Analysis
Reinforced beam analysis is carried out to check the nominal moment of the beam. When beam is analyzed than one already know about the beam cross section, steel area and effective depth of beam. In …
Continue readingLoading Design Pattern
Loads are the forces that come on the structure during construction or during service period. It is very necessary to define all the loads that structure is going to support, once the dimensional requirements have …

The cracking phenomena usually start at ITZ- level. This level is considered to be a very thin region having access water and less cement. When water is consumed due to hydration of any other kind …
Continue readingRole of Composite Material
A composite material usually consists of a matrix, a binder and reinforcement. Considering concrete as one material and reinforcement as another material with different properties, than it should be kept in mind that before any …
