Seepage flow
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 …
What is neutral axis and what is the limiting depth ?
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 …
Design procedure of singly RCC section as per IS 456: 2000 ?
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 …
Design steps for a doubly reinforced beam section
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. …
What is group index of soil?
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 …
Cracks in beams | Flexure crack and Shear crack
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 …
When do we need doubly reinforced beams ?
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 …
Why do we provide transverse reinforcement in beams?
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 …
Consistency of a clays : Atterberg Limits
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 …
Minimum and Maximum reinforcement in beams?
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 …
