Different Types of Steel bars Used in Construction

Steel bars, also known as reinforcement steel or rebar, are essential materials used in construction to provide added strength and durability to concrete structures. They are made from carbon steel and come in various sizes, shapes, and grades. In reinforced concrete structures, steel bars are used to resist tensile forces, which concrete cannot withstand on its own. The steel bars are placed in a grid pattern throughout the concrete structure, providing added support and resistance to bending, cracking, and breaking.

What are Steel Bars?
A steel bar is a long, solid metal rod typically made from carbon or alloy steel. It is a versatile and strong material in construction, manufacturing, and other industries. Steel bars often reinforce concrete structures to increase their strength and durability. They are also commonly used in manufacturing machinery, tools, and equipment, as well as in constructing buildings, bridges, and other infrastructure projects.

What is Dowel Bar in Construction?

In the modern world, concrete is the most popular building material for many different types of buildings. Concrete pavements are one of the essential components of a construction site. Concrete slabs are made and put in place to make a solid pavement that can handle the traffic. Construction workers use dowel bars to ensure these pavements are strong and stable. These bars help make sure that the concrete slabs are mechanically connected in the right way.

Riveting And Welding Of Steel

Riveting is the process of joining two metal plates with the help of nuts and bolts. In other words, it is a process in which a hole is made on the steel plates to be joined, the diameter of which is more than the nominal diameter of bolt. The rivet is then inserted and the head is formed at the other end. The rivets should conform to IS: 1929-1982 and IS: 2155-1982 as appropriate. High tensile steel rivet must be manufactured from steel conforming to IS: 1149-1982.

What are the Types of Frame Structures?

What is Frame Structure?
Framing is the process of mixing building materials to form the framework of a building. As a result, a framed structure uses beams, columns, and a slab to withstand gravity and other lateral loads. As a rule, these structures are employed to counteract the pressures and moments that emerge from the loading.

Characteristics of a Frame Structure:

  • A-frame structure is a carefully arranged set of beams, columns, and slabs that can withstand the tremendous stresses and moments generated by severe gravity and lateral loads.
  • They come together to form a framework of steel or concrete that supports the weight and transmits it to the ground without incident.
  • In a framed structural system, walls are used to enclose the resulting cavity. There are two types of walls here: load-bearing and non-load-bearing. Shear walls make up the bulk of the framed building’s load-bearing walls.
  • Pin or permanent connections join the frame’s structural parts.
  • Consequently, beams, columns, slabs, and shear walls are a framed structure’s primary structural or load-carrying elements (load-bearing walls).
  • The framework of a building may be fabricated from a wide variety of materials.

Different Types of Columns Used in Construction

What is a Column?
Columns are rigid vertical structural components meant to support axial compressive loads from beams and slabs and then transfer them to the ground via footings. The various loads created in a structure are carried by column to footings and footings to the soil. As a result, the column is critical to the overall load transfer mechanism, and the structure would be incomplete without it.

However, not every vertical member must be a column. A column is defined as a member with a length greater than three times its smallest cross-sectional size. If this criterion is not met, the vertical part is referred to as a strut.
The strength of a column is determined by the material employed, its geometry, form, cross-section size, and its length and position about the support condition at both ends.

Spread Footing – Types, Design, Advantages, and Disadvantages

What is Spread Footing?
Spread footings are commonly utilized to support each column of a building and the piers of a bridge. Construction of these footings is both cost-effective and economical. It works well in any soil with sufficient load-bearing capacity. Spread footing comes in various forms and sizes, including square, round, and rectangular. With stresses applied upward, this footing can operate as an inverted cantilever.

For the construction of spread footings, structural design codes and specifications assume a linear soil pressure distribution. As a result, designing spread footing is a lot easier.

Why is Revit Getting Popular Among Civil Engineers?

Architects widely use Revit for a number of reasons, but nowadays, it is gaining traction among civil engineers too. Civil Engineers widely adopt AUTOCAD to make plans for buildings, design for water tanks, and many more. Nowadays, this software is getting replaced by Revit as it offers 3D rendering quite quickly compared to AUTOCAD. Some additional blocks are also there in Revit that can be imported as plugins which are quite beneficial to place on the drawings without consuming much time.

Both AUTOCAD and Revit are the products of Autodesk, and they share many similarities despite having many differences. One of the main reasons Revit has become so popular is that it was built with the BIM process in mind, and it also works with cloud computing. This allows everyone participating in the project to get their hands on any information they need.

Design of a Lintel

Before coming to the design part, it is important to know the importance of lintels in structure. A lintel is a horizontal structural member that is present on top of doors, windows, etc. to support the top load falling on these openings. These are used for load bearing purposes, to transfer its load to the side walls and sometimes for decorative purposes. These can be made of wood or concrete; however, concrete is widely used due to its strength and durability. These can also be prestressed for better load carrying capacity.

Design Calculation for Slab

A slab is a structural element that is used to support ceilings and floors. It is made of concrete and reinforcements are provided to support it. It is several inches thick and it rests on beams and columns. It is estimated that a concrete slab lasts for about 30 to 100 years if it is built with good grade of concrete and steel. Usually for residential purpose M20 is used.

Design Calculation of an Isolated Footing

Footings are the bases laid on the soil on top of which a structure is erected. Thus, it is the foundation on which a building or any such structure stands upon. They are made of concrete having reinforcements inside them and are poured into an excavated ditch or conduit. Before the foundation is built, a test is done to assess the strength ofthe soil bearing capacity to ascertain the type of foundation to be built.

Given below are the types of footing and the situation under which they are applied is defined for better understanding-
