Steel is an indispensable part of construction. The possibilities presented by steel in the field of construction is not just limited to steel sections, but also as steel bars as reinforcement to cement concrete in construction of structures. The story of steel as a reinforcement presents a picture of innovation in the field of construction. Starting as iron as reinforcement to structures, to highly ductile mild steel to deformed bars (High yield strength deformed bars) and finally to thermo mechanically treated (TMT) steel bars, showcase an evolution of steel reinforcements to keep up with the needs presented by humans in the field of construction.
Corruption in both public and private undertakings is not an unusual or uncommon scenario for a resident in a country like India. The dangers of corruption for unlawful gains have lead to disaster, of which collapse ——– was discussed in —- blog. But ever wonder why not every structure or construct you have known where corruption has eaten up quality is still functioning as its supposed to. It’s not just God’s grace, but a large part of its credit goes to the Engineer who made the plans and necessary load calculations for the construct. So why do they make such calculations. On planning structures, an engineer has to calculate structural load which comprises of both dead loads and live loads acting on it, and also the environment loads and much more. This is so especially in cases of bridges and structures where live loads are more prominent. In this blog we will be discussing more on how loads are calculated for buildings.
Cyclone, as described by the meteorology is a large scale air mass that rotates around a strong centre of low atmospheric pressure. Well, so is typhoons and hurricanes. Cyclones, typhoons and hurricanes are the same phenomenon, but are known differently in different parts of the world. With Odisha in the wake of a massive cyclone Fani and the world in discussion of the recurring and ever strengthening cyclones observed around the world as a man made disaster in the era of ‘humans’, let’s talk on how to build to survive the cyclones and not just let our homes be another matchstick on fire.
We see structures going up everyday, but do we realize the effort behind it. Construction requires great commitment, resources and technical skills. When it comes to resources, we are familiar with the construction materials such as Bricks, Concrete, Reinforced steel and such. When we look at the history of the construction, we have come a long way from using stones to bricks to different variations of bricks. In any construction, the most needed component apart from concrete and steel are bricks, obviously.
Constructing buildings is not an easy task, It requires a lot of resources, technical skills, dedication and commitment. When we talk about the resources, the most vital components for constructing buildings are reinforced steel and concrete. Reinforced steel is primarily known for its excellent strength and ductility which provides the necessary strength to withstand the load of the structure. However, there are several factors that can affect the strength of the steel in such a way that it becomes extremely dangerous to the whole structure, and one such factor is rusting.
Concrete is the most vital material in the construction of buildings. There is no need for any sort of familiarization for us. It is right around us, buildings, roads, bridges, etc, all these structures are made with concrete. It is impossible to imagine a structure without concrete. The use of concrete has a long way back since ancient times. The arrival of concrete drastically changed the course of architecture in the world.
Steel, the most versatile, strong and durable material for reinforcing concrete for constructing buildings. No doubt, it is the only material so far that has proven successful to bond with concrete for reinforcement. The main reasons are, One, steel has high tensile strength and is able to withstand the tensile forces in a structure which the concrete lacks. Second, the thermal coefficient of expansion of steel is similar to that of concrete.
The introduction of reinforcement drastically changed the phase of construction of building structures of steel. Reinforced steel provided the necessary tensile strength which the concrete lacks. Today, very few constructions are done without using reinforced cement concrete. At the current scenario, the most used reinforced steel bars are the Thermomechanically Treated (TMT) steel reinforced bars. They are preferred for their excellent tensile strength and optimum ductility. The TMT steel bars are of different grades namely Fe 415, Fe 500, Fe 550 and Fe 600.
TMT steel reinforced bars have been used in constructions of building structures for a long time. They are primarily preferred due to the advantages offered in terms of tensile strength and ductility ratio. TMT Steel reinforced bars consists of different grades namely Fe 415, Fe 500, Fe 550 and Fe 600. Because of the availability of different grades and many dealers promoting different versions of the steel reinforced bars, purchasing the right TMT steel reinforced bar is an important task
