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

A macroelement for waffle slab analysis
Computers & 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 ...

Eccentric Punching on Edge Waffle Slabs
2021This paper presents the test results of six 1/10th scale micro-concrete waffle slabs subjected to eccentric punching at the vicinity of edge columns. It was observed from tests that the punching mechanism of slab having their edge column is located by the free edge to be similar to those having their edge column at the centre of the edge solid region ...

Dynamic Characteristics of Prestressed Waffle Slabs
Journal of Structural Engineering, 1990The dynamic response and fatigue behavior of rectangular and skew prestressed concrete waffle slabs are investigated. Such slabs have several advantages over the more conventional slabs when used as decks for concrete bridges and as process floors in semiconductor manufacturing plants.

Feasibility of waffle slabs for bridges
Canadian Journal of Civil Engineering, 1983Waffle slabs, although extensively used in buildings, are rarely employed in bridges. Part of the reason for this situation is that a waffle slab, forming essentially a two-way load distribution system, is intuitively considered by many bridge engineers to be incompatible with the basically one-way load transferring system of a bridge.

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
