INTRODUCTION 1.1 General Background Buildings are composed of various structural elements such as slabs, beams and columns.Corrugatedweb profile can be more economical than conventional plate and improve in the structure. Beam, column and slab with corrugated shapes have been extensively used in structural application such as building and bridges.Commonly used Corrugated shapes are trapezoidal, sinusoidal and rectangular .Corrugated shapes shows large resistance to shear buckling and has large load carrying capacity. The aim of this study is to determine the maximum load carrying capacity of connection with corrugated beam, column and slab. Now a day’s building and civil infrastructures are becoming larger and higher, the demand for horizontal structure members, which are suitable for long spans so structural steel require high strength but steel member also have many weaknesses, such as less resistance to bucking, excessive deflection, fatigue strength, vibration. To overcome these disadvantages various types corrugated shapes are developed. corrugations can be applied to strengthen the beams, columns, and slabs of buildings and bridges. It is possible to increase the strength of structural members. The main scope of this study is: to control the bending moment of member, to avoided shear buckling, to implement economic and safetyconstruction,toimprovethe load-bearing efficiency. The main objectivesofthisstudy are follows:Comparative study of load carryingcapacityofthree different types of cross sections of corrugated beam and column,Comparative study of buckling behavior of three different types of corrugated columns,To create corrugated beam column joint by finding the best load carryingcapacity of corrugated beam and column,Comparative study of load carrying capacity different types of beam column joint and finding the best among that,Comparative study of the best load carrying capacity of corrugated beam columnjoint with three different types of cross section of corrugated slabs,To determine the maximum load carrying capacity of connection with corrugated beam ,column and slab joint.

NUMERICAL INVESTIGATION USING ANSYS WORKBENCH 16.1 2.1 Base Model Numerical modelling of corrugated shape with different sections were done using ANSYS 16.1 WORKBENCH, a finite element software for mathematical modelling and analysis. The dimensions and material properties of all models are same and is given in Table 1 and Table 2 respectively.
