Before discussing seepage here in this article we have already discussed about seepage in Permeability of soil and its measurement and also in seepage force. But the difference between the topics is the dimension. In the earlier topics we have discussed about the one dimensional flow of water through the cross section of soil. But …
Let us consider an example where a beam is initially in unstressed position. Now when a uniform bending moment is applied along the length of beam , then the beam will bend. When the beam bends the top surface of the beam is in tension and the bottom surface is in compression. So it is …
Before moving into the design procedure of a R.C.C beams you should be aware about the different types of beams available. There are basically seven types of beam depending upon the support and geometry of the beam section, they are: Simply supported beam Fixed beam Overhanging beam Double over hanging beam Continuous beams Cantilever beams …
To start the design of doubly reinforced beam with you should have an idea about doubly reinforced section. As the name implies doubly reinforced beams means we are providing the reinforcement in both the zones. In the case of a beam the zone is basically compression and tension zone. Check this post to know more …
Before discussing about the Group Index (GI) we will first discuss about the need and significance of GI. Significance This group index is developed by US Bureau of Public Road. They wanted to develop the soil classification system called the Public Road Administration classification system which was meant for road construction. Actually the famous name …
In any structural system crack arises because of stress in the structural system. Failure of a reinforced concrete beam in flexural shear will not result in a sudden failure. But yes gradually it will decrease the flexural strength and result in failure of structure. In reinforced concrete beams, cracks occurs because of flexural and shear …
As the name implies doubly reinforced beams means we are providing the reinforcement in both the zones. In the case of a beam the zone is basically compression and tension zone. At the analysis stage if the value of moment of resistance is less than the required bending moment and also if there is a …
Transverse reinforcement in beams is provided mainly to resist the shear forces or forces which act in a direction perpendicular to the longitudinal direction of reinforced concrete beams. We follow IS – 456:2000 design procedure to calculate the reinforcement required for resisting shear force. Most commonly use stirrups as transverse reinforcement. As you all know …
This topic is bit on higher side for the readers who are interacting for the first time with soil mechanics. We define consistency by the firmness of soil in qualitative manner. Sounds like very complicated parameter. Don’t worry this is so easy to understand. “Consistency indicates the relative with which a soil can deformed. We …
As we have already discussed in the previous port reinforced concrete beam is a composite section made of concrete and reinforcement. In this post you will get the answer of why we should account for minimum and maximum reinforcement. Concrete is good in compression and is bad in tension. So it is very much required …
