Abstract - In olden days, the large number of structures are
design skills and application techniques, structural strengthening and structural repair necessary for such projects. As such, the Engineer must rely on his or her expertise in using mechanical and structural behavior principles to develop comprehensive retrofit solutions.
constructed using older design codes all over the world and they are deficient to carry a loads as per new design codes. The maintenance of such structures is difficult and incurs a huge amount of public money and time. The rehabilitation and restoration of a structure is one of the most important things in civil Engineering field and also a very challenging thing is to select a strengthening method that will enhance the strength and serviceability of the structure. Hence the use of FRP composites is one of the strengthened method adopted in this work and this can be done by developing IOS application because as in present days use of application is increasing day to day and person to person. So keeping in that the development of IOS application is done and validated and used for the case study of residential building in which the beams were retrofitted for extra live loads.
1.2 External strengthening by the usage of Fiber Reinforced Polymers (FRP) composites
As of late the civil designing field has begun to utilize FRP for structural support. This enhances a few extent such high quality weight proportion, high-firmness weight proportion, adaptability in plan, non-destructiveness. For the most part FRP materials are non-destructive, non-attractive and impervious to different sorts of chemicals they are progressively being utilized for outer support of existing concrete structural. This kind of utilization is normally alluded to as inside fortification. Also, carbon fiber fortified polymer (CFRP) strips can be utilized as outer fortification for expanding the load-conveying limit of ordinary steel and fortified concrete beams. In this kind of utilization, the CFRP strips are clung to the outside tensile face of a beam to supplement its flexural limit.
Key Words: Retrofitting, Carbon Fibre Laminates, Flexural Strength, IOS Application, RC Beams.
1. INTRODUCTION The reinforced concrete structure has very much important in these days. The solidness for this kind of structure has all the more relatively developed by utilizing other sort of materials. The upkeep is anything but difficult to sort of the structures. In a presently days, the rehabilitation and rebuilding of a structure is a standout amongst the most vital things in structural engineering field and furthermore an extremely difficult thing is to choose a fortifying technique that will improve the quality and serviceability of the structure.
1.3 Growing importance of software application in daily life The world is murmuring to the tune of portable applications where there is an answer for everything without exception with cell phones. The mechanical advancement by the different Mobile App Development Companies recommends that as an ever increasing number of individuals are getting dependent on versatile applications to satisfy such a variety of prerequisites while moving. Portable applications have in fact turned into a guide, a companion and an answer discoverer for individuals who are so occupied in their everyday lives. Apple appreciates an imposing business model and is places high on top of the interest for the Windows applications. It has likewise expanded throughout the years in light of the different new elements identified with social advertising, games and media news, informing administration and the new forms concentrating on the speed consider.
1.1 Retrofitting There is no single solution that offers a simple, straightforward method for all repair and strengthening projects. Further, the process of repair and retrofit of existing structures are complicated because most of these structures are occupied, and much of the mainstream construction community’s expertise is centered on new construction. However, success can be achieved if repair and strengthening systems are tailored to serve a structure’s intended use without interfering with its occupants or function. The key to success is a combination of different
