Abstract
Strut-and-tie model is being used increasingly for analysis and design of concrete structures with pronounced D-regions in the recent years. In strut-and-tie model the load carrying mechanism of a structural member is approximated by means of struts representing the flow of compressive stresses and ties representing the flow of tensile stresses which enables a direct visualization of the stress flow in the structural member to the designers.Waffle slab is an attractive and economical alternative as compared to solid and voided slab system. With a grid of intersecting ribs it essentially forms a D-region and currently numerical and empirical approach is used in the analysis and design of waffle slabs. A new three dimensional strut-and-tie model is proposed for a rational analysis and design of waffle slabs and to predict the strength and mode of failure of these slabs. The proposed strut-and-tie model shows good correlation with experimental results from literature. Also new software “STWAF” is developed for design of waffle slabs using strut-and-tie model.
