STRESS AND DISPLACEMENT ANALYSIS OF DEEP BEAMS WITH WEB OPENINGS

Abstract

Multi story buildings are common in urban region. Day by day they are becoming more slender, generally multi story buildings are of open ground story. Due to parking at ground story the architectural planning will be disturbed in upper story therefore structural engineer has to initiate floating columns from first story, so as to have ground story open for parking. Floating columns have to be supported by transfer girder or reinforced concrete deep beam. The analysis and design of transfer girder or transfer plate should
have more concentration as far as displacement and stress analysis are concern. To this particular study simply supported and continuous transfer girder have been considered, transfer girder taken are subjected to huge point load generated from the floating columns. A detail stress and displacement analysis have been done for both the girder by considering the web openings for understanding the behavior of transfer girder or plates and finite element modeling with different element sizes have been done to have a greater accurate evaluation of result using the software SAP 2000.Different types of loadings like Impact load in the form of triangular function time history function, Impact load in the form of trapezoidal time history function and Sinusoidal loading has been considered. Results obtained from this study has shown us greater amount of stresses and displacements with respect to the applied loadings and openings when considered. Finite element modeling has shown us greater accuracy and precise evaluation of results.
