Mechanical behaviour of a steel fibre reinforced concrete ground slab

Abstract

Concrete ground slabs are essential components of modern buildings and structures. This common structural element has been used in great numbers in buildings and structures of various forms and sizes throughout the world for decades. The utilisation of fibre reinforced concrete for ground slab purposes has gained significant momentum in recent years. The third edition of report TR34, published by the UK Concrete Society in 2003, has paid attention to the design of concrete ground slabs with significant emphasis on the use of steel and synthetic fibres as an alternative to fabric reinforcement. TR34 is currently under review and this paper attempts to contribute towards a better understanding of the mechanical behaviour of steel fibre reinforced concrete slabs under step loading conditions. This work reports on tests carried out at different locations (centre, edges and corners) of a 6 . 0 3 6 . 0 3 0 . 15 m steel fibre reinforced concrete slab. A significant difference was found between the test results and theoretical values derived using available design codes.

Two-way slabs: Experimental investigation of load redistributions in steel fibre reinforced concrete

“…A common application of SFRC is in industrial flooring, i.e. slabs on ground [6,7]. More recently, SFRC has also been used as the only type of reinforcement in elevated slabs [8] or in combination with conventional reinforcement [9].…”

Numerical analyses of interaction of steel-fibre reinforced concrete slab model with subsoil

“…The research mentioned in this article contributes to a better understanding of the behaviour of foundation slabs from reinforced concrete and fibre-reinforced concrete for various types of loads. In 2012, Alani in cooperation with Beckett and Khosrowshahi published article [3], which focuses on design of concrete foundation slabs with special emphasis on use of steel and synthetic fibres and alternative to reinforcing. The Tongji University in China conducted tests and comparison of two foundation slabs.…”

Experiments on Fiber Concrete Foundation Slabs in Interaction with the Subsoil

“…The high number of fiber concrete types leads to a wide variety of mechanical properties and shapes in load-displacement diagrams, as shown in Figure 1. Material properties are influenced by the type, shape, and amount of fibers, as well as by the concrete mixture [15][16][17][18]. The multitude of fiber concrete variants usually necessitates individual structural analyses for particular tasks.…”
