---------------------------------------------------------------------------------***----------------------------------------------------------------------------method for strengthening aging reinforced concrete Abstract - Most of the structures regularly we see are building by wrapping structural member with carbon fibre made of reinforced cement concrete. The building was sheets. In this paper, author examined the stress- strain designed according to the state of the art over 38 years ago relationship of concrete elements with rectangular cross it did not meet the present-day requirement the project section reinforced by wrapping with carbon fibre sheets. study deals with strengthening and enhancement of performance of existing structure by mean of retrofitting, so Anurag Mishra design and application of retrofitting that structure can perform well when it would be subjected techniques in various structure papper is focused on to additional loads over it. Building is residential community structure with lack the required strength as per the building nirlon colony having G+5 stored determination of guideline of earthquake building code to sustain the load and moment carrying capacity of structural element seismic force the strength enhancement of structure is before and after extension method applied for strengthening based on the concept of improving the flexibility stifness, of structure and design of the existing structural elements ductility, unity of the structure the method of retrofitting such as RCC beams and column according to the load improving the seismic force sustaining capacity of various carrying capacity required. components of building without stress concentration at critical points. Keywords: Retrofitting, R.C.C, Nirlon colony UDCPR Punit kumar seismic retrofitting method providing external strength to building under lateral loading we used Etabs 2015 computer for the analysis of structure there is a different load live load, dead load and seismic load in seismic analysis the parameter such as maximum displacement / maximum story drift overturning moment and story shear are calculated in the present technical papper.
INTRODUCTION Retrofitting of an existing rienforced concrete structure includes repair is a process of repairing of faculty structure either masonry or R.C.C It can also be used to repair old or damaged structure due to any uncertain loading. Retrofitting is needed when the assessment of structural capacity results in insufficient capacity to resist the forces to expected intensity and acceptable limit of damages.It is the modification of existing structure to make them more resistant to seismic activity ground motion or soil failure due to earthquake the retrofitting is also applicable for other natural hazard such as tropical cyclones tornadoes severe winds and thunderstorm.The results generated by the adopted retrofitting techniques must fulfil the minimum requirements on the building codes such as deformation detailing strength porposed work and objective My research project aims at doing seismic evaluation of building and suggesting how to retrofit the failing members using retrofitting methods.
Rahul mimje strength of existing building using retrofitting technique Now a days retrofitting becoming popular around the world as most of the important structure some other like old structure for the future earthquake and other environmental forces retrofitting is much better convinent retrofitting helps to enhance the strength resistivity and over are life span of the structure.
METHODOLOGY The project is for give a strength to a building Before the starting retrofitting technique for the building its important to know the exact damages of the structure and then used then use retrofitting technique for the increase load capacity of beams column and wall. We have calculated area statement under UCCPR for future planning of new building after demolish of old structure
LITERATURE REVIEW Author Mohammad “parameter affecting behaviour of reinforced wrapped with CERP sheets” has studied aging building structure has become a world problem Is particularly serious in developed countries. A construction
