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.
The previous blog explained about the evolution of steel using different techniques and also how it changed the economic status of the world. Steel is mainly preferred as reinforcements due to their high tensile strength. In earlier times Iron bars was used as reinforcement but it became unsuitable due to formation of corrosion very quickly. It was replaced by Mild Steel (MS) reinforced bar. Even though Mild Steel rebars has good workability, ductility and anti corrosion properties, it has poor bonding with concrete since it’s outer surface is smooth.
Steel has been a vital tool for mankind since its inception. Steel is the major component in almost everything starting from buildings, bridges, automobiles to pieces of machinery. Discovery of steel and it’s production dramatically changed the economic status of the world. Steel is an alloy of Iron and Carbon in which the carbon content is at 2% (Above 1%, it is classified as Cast Iron).
