To Quantify the Improved Response of Steel Plate Embedded and Jacketed R.C.C. Beam in Shear and Torsion

Abstract

In developing countries, often during construction, rapid modifications are required in designs to fulfil the demands of the strength of the structure to make it structurally safe and sound. Because of the increasing population and a small amount of ground surface we are moving from small buildings toward high-rise structures. As we advance in construction, there are certain limitations where the engineer cannot increase the cross-section of a beam to increase its strength. This limitation is due to modern structures need maximum space available and mainly because of aesthetics to be provided inside the structure. This situation has led us to provide Composite Beams which can be used to overcome the deficiency in the loading capacity of the structure and rigidity of the structure. To improve structural strength against loading and ductility of the structure against earthquake, various techniques are used like FRP Plates, Steel Plates, etc. But a more economical of all these options is to use galvanized zinc-coated steel plate which can be jacketed around the member to increase the flexural, shear, and torsional capacity and can be embedded inside the member to increase the ductility of the structure. So, the structure gives better performance than conventional beams under different types of loading.
