ANALYSIS AND DESIGN OF TWO WAY RECTANGULAR ORTHOTROPIC SLAB WITH INTERIOR ENCLOSE OPENING WITH ONE SHORT BOUNDARY INTERMITTENT SLAB USING YIELD LINE THEORY

An endeavour has been made to evaluate the two way rectangular orthotropic slab with interior Enclose opening with one short boundary intermittent slab using yield line theory. Keeping in view the basic principles of yield line theory, all possible yield line patterns are considered for the given configurations of the slab subjected to uniformly distributed load (udl). A computer program has been developed to solve the virtual work equations derived in this paper. Relevant tables and charts for given data and the governing admissible failure patterns of the slab for different sizes of openings are presented using the affine theorem. In this paper, the authors also present the transformation of orthotropic slab into an equivalent isotropic slab using the affine theorem. The analysis is carried out with aspect ratio of opening quite different to that the slab.
