EVALUATION OF EFFICIENCY OF REHABILITATION SCHEME OF VIERENDEEL GIRDER

Abstract

The significant advantage of vierendeel beam system in building construction is that they can be used in portal frames, taken suitable advantage of the member flexural and compression resistances eliminating the need for extra diagonal members. For this reason, they allow greater interaction with building services, enabling a free space for pipes, ducts, etc. Due to tremor, this-structures are damaged partly or totally. In general, such structures are repaired and used again. In this study, two bay single storey R.C. bare frame is carried out in experimental manner. The R.C bare frame is retrofitted by using infilled, strut, GFRP and CFRP. All these frames were tested under static cyclic loading. This paper summarises the tests experimentally carried out to develop an efficient strengthening method for seismically affected vie rend eel structures. The experimental results were compared by using a finite element software. In this study shows that the retrofitted vierendeel girder shows more stiffness than the R.C. frames.
