Comparative study and Environmental Effect of various parameters on RCC, and LWSS for G3, G6, and G9

Civil Engineering

In this paper we discuss the comparative study between RCC structures and Light weight steel structures. What are the environmental effects on the steel and precautions done for that also discuss in this paper. What type of connections and material used for the construction of light weight steel structures? A heavy reinforced concrete column, seen before and after the concrete has been cast in place around its rebar cage Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete sets. Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Steel frame is a building technique with a "skeleton frame" of vertical steel columns and horizontal I-beams, constructed in a rectangular grid to support the floors, roof and walls of a building which are all attached to the frame. The development of this technique made the construction of the skyscraper possible. For the maintenance of reinforced concrete structures and buildings, it requires periodic inspection. In that case there is very little awareness in civil engineers and other discipline. As a result, many of the times due importance is not given to the repair and maintenance of the building. But now a day it has become necessary to give more attention towards the repair and maintenance of old and damaged building structure. Hence, in depth requirement has been generated for structural repair, restoration and strengthening of RCC structures. New and innovative techniques have been developed in the repairs of concrete structures. Light weight steel structures construction speed is more than the RCC structures. Time is main factor in this two structures and also strength. Light weight steel structures are super-quick to build at site, as a lot of work can be prefabbed at the factory. They are flexible, which makes them very good at resisting dynamic (changing) forces such as wind or earthquake forces. A wide range of ready-made structural sections are available, such as I, C, and angle sections .They can be made to take any kind of shape, and clad with any type of material .A wide range of joining methods is available, such as bolting, welding, and riveting. Thus ,Purpose of this project is which structures is more economical and construction speed and strength also matter. Also environmental effects on the steel and new technique of precautions for this. In this projects we conclude that It is conclude that steel structure is more resist as compared to the normal concrete structure . A building constructed using steel has less dead load on it, even the bending moment and shear forces acting are less as determined in this work .Speed of construction is another important advantage of steel structure. Since Standard sections of steel are available which can be prefabricated in the workshop, they may be kept ready by the time the site is ready and the structure erected as soon as the site is ready. Hence there is lot of saving in construction time.
