The shear key is a structural element designed and provided in different structures to provide resistance against lateral forces like earthquake forces and sliding forces in the different structures such as bridges, retaining walls, the basement of residential buildings, precast buildings and culverts, masonry walls in seismic regions, and steel columns. A shear key can … Read more
Different types of Stirrups are used in the construction industry such as Single Legged Stirrup, Two-Legged Stirrup, Three-legged Stirrup, etc. Stirrups are rectangular steel pieces used to resist lateral shear stress and diagonal tension stress in RCC structures. Stirrups help to hold in place the primary reinforcement bars and prevent buckling failure in columns. Depending upon … Read more
Sunken Slab The sunken slab is provided in the washroom or laundry areas where water pipes are installed below the floor level. The depth of the sunken slab is normally 20 cm to 30 cm below the floor level. Depth depends upon the size of the duct or any other pipes installed below the floor … Read more
In this article you will learn about crank bar in beam, slab and column. Crank bar also called as bent Up Bar. I will also describe why crank is provided. Definition Crank Bar is also known as the Bent Up bar. It is provided on top of the reinforcement to resist negative bending moment/Hogging at the supports … Read more
What is Retaining Wall? A retaining wall is a structural wall that is designed and constructed to resist the lateral pressure of soil. Lateral pressure can occur due to earth filling, liquid pressure, sand, and other granular materials behind the retaining wall. In other words, A retaining wall is a structure that retains material behind … Read more
In this article, we will describe the perfect truss, imperfect or deficient truss, and redundant truss. First, let’s know what is Truss. A Truss is a structure consisting of straight Slender Rods connected only at their joint. Slender Rod – If the diameter of rods is smaller compared to its length then this type of rod … Read more
Methods Of Structural Design Structural design can be accomplished using three primary methods: working stress, limit state, and ultimate load. Initially, the working stress method was utilized for designing both Reinforced Concrete and Steel structures. However, due to certain drawbacks of the working stress method, the Ultimate Load method was introduced. In recent times, most … Read more
What Is T Beam? It’s just a rectangular beam cast monolithically with the slab-shaped as T. T-beams possess a low volume of concrete. Additionally, they lessen the floor-to-floor height since the flange is already part of the slab. These two things in combination significantly decrease the concrete needed for the building, cutting down both cost … Read more
What Is Cantilever Beam? A cantilever beam can be defined as a beam that is supported on only one side. In this way, one end is fixed and the other end is exposed beyond the support. The beam transmits the load to the support where it can manage the moment of force and shear stress. The moment … Read more
What Is Dowel Bar? Dowel bar is a short round, smooth steel bar used to stipulate a mechanical connection between slab without restricting horizontal joint movement. These bars are chiefly used in jointed plain concrete pavement (JPCP) to carry the additional stress and load-induced due to the moving vehicle. There are two types of dowel … Read more
