Mezzanine words come from the Italian word “mezzano” which means middle. As the name suggests Mezzanine floor is the middle floor of the building. It covers only a small area compared to the main slab in the building. A mezzanine floor is built between two permanent floors in the building. Normally, it does not build … Read more
What Is Simply Supported Beam? A beam supported on the ends which are free to rotate and have no moment resistance is known as a simply supported beam. The simply supported beam is quite possibly the most simple construction. It includes just two supports, one at each end. One is a pinned support and the … Read more
There are different types of load works on the structure. These loads are considered to design safe structures. Dead load Imposed load or live load Wind load Snow load Earthquake load 1. Dead load The dead load is the self-weight of the structural members. It is a permanent load on the structure. Normally dead load … Read more
Non-threaded strong joints that are normally made of steel or aluminum of head and sank is known as Rivet. Riveted joints Riveted joints are the joints that are perpetual, comprising of fundamentally two parts that are controlled together by the bolt, head at the top, and tail (barrel-shaped stem) at the base. Types of Riveted … Read more
RCC beam can be classified as balanced, under-reinforced, and over-reinforced sections based on the percentage of reinforcement it has. In this post, I have discussed the balanced, under-reinforced, and over-reinforced beam sections. Balanced Beam Section Reinforced concrete beam (RCC) sections in which the tension steel also reaches yield strain at the same time as the … Read more
In a doubly reinforced beam, reinforcement is provided in the tension zone and compression zone. (as shown in the above figure). The moment of resistance can not be increased by increasing the amount of steel in the tension zone. It can be increased by making the beam over-reinforced but not more than 25 percent on … Read more
In this article, we have covered the difference between Singly Reinforced Beam and Doubly Reinforced Beam based on reinforcement in tension and compression zones of the RCC beam. Singly reinforced beam and double reinforced beam are two common types of reinforced concrete beams widely used in construction. These beams resist bending and shear forces to … Read more
If the depth of the beam in the slab is equal to the depth of the slab, it is known as a hidden beam or concealed beam. You can not see concealed beam after slab casting. The normal beam has a larger depth than the slab but the concealed beam has the same depth as of slab. … Read more
This article explains various types of failures in beams. Failure of a single structural member can lead to complete structural collapse. That is why we need to identify all types of failures in the beam. There are two types of failures in beams. Flexural failure occurs due to imposed load exceeding the flexural capacity of the … Read more
Waffle Slab A waffle slab is made of reinforced concrete with holes underneath, giving the appearance of waffles. Waffle slabs are preferred for large spans greater than 12 meters. Waffle slabs are stronger than flat slabs, flat slabs with drop panels, two-way slabs, one-way slabs, and one-way joist slabs. It is used to avoid many columns interfering with … Read more
