Performance study of steel-concrete composite beam involving flexible shear connector

Abstract

The paper presents the results of an investigation on steel-concrete composite beam subjected to static loading. An experimental investigation and analytical study using finite element analysis (FEA). The load carrying capacity of the steel-concrete composite beam is presented. The steel-concrete composite beam is embedded with 19 mm stud shear connector. The interaction of steel-concrete layers of composite beam with headed stud shear connector due to the application of flexural load is analysed. The experimental results are compared with those of analytical modelling using ANSYS 10.Biographical notes: Currently, B. Raguvaran Balasubramanian doing research in the area of steel-concrete composite structures based on this, he has published more than three international journals in various publications based on research area in structural engineering and construction engineering.Rajaram Baskar has been acquired experience in the design of steel structures. He has completed his PhD in the year 2005, he is working as a Professor at Annamalai University, one of the famous institution in India and all over the world. He has published more number of international journals in various publication based on research area in structural engineering and construction engineering and he has conducted national conferences about technical study and design of various types of structures. And now, he is also guiding to the PhD research scholar in his area effectively and technical oriented subjects.

Nonlinear analysis of steel-concrete composite beams with flexible shear connectors

“…In addition, the load-slip behaviour test model by Balasubramanian BR et al[1] and the present ANSYS model generate close relation. Less amount of slip is observed in case of finite element model…”

“…Due to interaction, slip is one of the important features in deciding the behaviour of composite beams. Slip obtained by the numerical analysis using ANSYS is recorded and compared with the test results obtained by Balasubramanian BR et al [1], and Yan JB et al [7] as shown in 'figure 6(a)' and 'figure 6(b)' respectively. Good agreement is established between the present numerical model and the experimental results available in literature.…”

“…Modulus of elasticity, poisson's ratio, yield and ultimate strength characteristics of structural steel along with shear connector are taken from the stress-strain curve [1]. Apart from these two materials, reinforcement bar is considered as elastic-linear-work-hardening material, with tangent modulus equivalent to 1/10000 of its elastic modulus [5].…”
