Abstract Waffle slabs are lighter in weight than an equivalent solid slab which helps in diminishing the weight with its voids. This study is performed to investigate the behaviour of the waffle slab. Waffle slab types of construction are economical for building where there are long spans, over between 5 m and 6 m with light to moderate live load. It

Behaviour of punching shear in normal RC slab and waffle slab
Asian Journal of Civil Engineering, 2018This study presents the behaviour of punching shear in waffle slabs at slab–column joints subjected to concentric loading. Although it was observed that waffle slabs are very similar to that of flat slabs, the shear capacity is relatively reduced because some of the potential surfaces are lost when it extends into waffle section. The current IS code of

Curved structures in waffle slab construction
Engineering Structures, 1994Abstract Horizontally-curved concrete waffle slab structures are sometimes used as superstructures of bridges and as floor slabs in large exhibition halls. The idealization of a horizontally-curved wide structure as a curved beam or an assemblage of curved beams leads to inaccurate results. Although the finite element technique can be used to analyse

A macroelement for waffle slab analysis
Computers and Structures, 1982Abstract Behaviour of a waffle slab under transverse loading is investigated through a series of three-dimensional finite element analyses, and modal analysis of a deformed waffle slab cell. “Macroelement” concept is introduced, taking an advantage of the repetitive nature of waffle slab cells and the fact that only few deformation modes participate ...

Design of horizontally curved waffle slab structures
Engineering Structures, 1997Horizontally curved concrete slab structures are often used in bridge superstructures as well as in large auditoriums with a minimum number of supports. A method is developed to analyse and design such structures based on their ultimate load-carrying capacity. The basis of this method is the yield-line theory.

Rigidities of concrete waffle-type slab structures
Canadian Journal of Civil Engineering, 1979Analytical expressions for the orthotropic rigidities of concrete waffle-type slab structures are presented; the expressions are valid for both the precracking and postcracking stages and are therefore applicable to reinforced and prestressed concrete structures.
