Voided biaxial slab


Voided biaxial slabs cast onsite take longer to construct than prefabricated slabs, but are sometimes cheaper. In a typical casting procedure, a decking of formwork is constructed out of metal or wood. This provides temporary support for the voids and the curing concrete. After the decking is constructed, reinforcing mesh is installed to ...

The voided slabs rely on these voids created within the concrete during the time of casting. The arrangement creates an array of hollow boxes in the slab that support the flat surface. The system hence provides support in both directions and safely transfers the load to the vertical member. It is hence called voided biaxial slabs or biaxial slabs.

A similar approach was developed in the 1990s by Jorgen Bruenig, who developed in Denmark a type of biaxial hollow slab (today better known by the BubbleDeck trade name).

reduction factor of the biaxial voided slabs, α, compared with the soli d slab with an equivalent . thickness. As shown in Table 3, this m ethod could estimate the shear capacity of the biaxial [20].

This paper reviewed the numerous studies have been prepared on voided biaxial slab system. conventional Slab are a standout amongst the most widely recognized parts in present day building development devouring a large portion of the concrete. The Advantages are lower power as comparison consumption than conventional slab - in both production ...

The Two-way hollow slab system (biaxial voided slab) is an innovative slab system, being adopted all over the world as an alternate for the conventional solid slab. It reduces the self-weight up to 50% in comparison with solid slabs without significant change in its structural performance. The voided slab consists of void formers in shapes like spherical, donut, and cuboid. Experimental and ...

1. Introduction. Voided slabs were first introduced in 2000 to lighten the slabs' weight up to 50% by removing a vast concrete volume due to placing voids inside slabs [1], [2].The voided slabs generally incorporate a regular array of voids of different shapes distributed uniformly along the two axes of the slab plan; therefore, they are sometimes called biaxial voided slabs [3].

A biaxial voided slab system is introduced to improve the solid slab system's performance by creating voids in the concrete and removing ineffective material. In this study, the bending behavior of voided slabs is investigated numerically. For this purpose, a numerical ABAQUS model is presented and then verified using available experimental ...

Voided biaxial slabs, also known as biaxial slabs or voided slabs, are a type of concrete slab that has air-filled voids in order to reduce the amount of concrete needed and decrease the environmental impact of construction. These voids also make the slab lighter allowing for up to 50% of the slab volume to be removed.

Slabs designed with the voided slab system increase the earthquake resistance of the structure by creating a more rigid diaphragm compared to one way ribbed slabs. The design of traditional one way ribbed slabs have been limited by rules and regulations. ... Working in two directions (biaxial) Reduction in building self-weight; Reduction in ...

A biaxial voided slab is an innovative type of slab system developed recently, that has proven its excellence in terms of its structural, environmental, and economic benefits. In the present research, an experimental study was carried out to investigate the two-way flexural behavior of biaxial voided slab using the cuboidal shape of void formers.

Slab is largest member which consumes concrete. If the load acting on the slab is large or clear span between columns is more, the thickness of slab increases. It leads to consume more material such as concrete and steel due to this, self-weight of slab is avoid these disadvantages voided slab system is used. Reinforced concrete slab with plastic voids is a new and innovative type of construction.

The concept of voided biaxial slab system is to replace the nom-working concrete in the slab with voids. The immediate results is optimization of concrete up to 35% reduction in the slab self-weight while still providing a high equivalent stiffness. This will enhance the bearing behavior on the whole structure elements.
