COMPARISON BETWEEN BUCKLING ANALYSIS OF TAPERED WEB & CORRUGATED WEB

To increase the shear capacity of web of large steel plate girders, the web with different patterns such as tapered web, haunches, corrugation of different shapes are used. The corrugated steel plate is widely used structural element in many field of application because of its numerous favourable properties. Tapered (varying depth) web is one of the new technique proposed in design in order to achieve economy and to reduce its self weight . Present work is focusing on the determination of buckling strength and economy of corrugated web and tapered web. In the present study comparison has been carried out between plate girder with corrugated web beams and tapered web beams. The finite element analysis of a plate girder is carried out using ANSYS. The main aim of this project is to determine the buck ling strength of corrugated web and tapered web subjected to shear for transverse loading at mid span. Also to check the economy and compare it with tapered web plate girder. Research work involves the finite element analysis of plate girder for different conditions like, i) Tapered Web beams ii) Corrugated Web Beams with Rectangular ,Trapezoidal, Web Corrugations. The main comparison parameters are i) static behaviour, ii) buckling behaviour
