For more information about ASclick here: One of the elements used to administer this change is the “Ys” range Ys being the measure of potential movement in mm of the soil. Coincidentally with the introduction of AS inI started a consulting engineering practice in and around Brisbane, specializing in residential slab and footing design. Frank Van der Woude B. It is measured in millimetres and suggests the value of which the soil might move due to changes in moisture.

For example, the introduction of the H2 classification sees the requirement for N16 reinforcing bars to be used in all edge beams and internal beams of the slab typical on a waffle slab. A soil’s Ys rating is its indication of movement potential. This Standard sets out the criteria for the classification of a site and the design and construction of a footing system for a single dwelling house, townhouse or similar structure which may be detached or separated by a party wall or common wall, but not situated vertically above or below another dwelling, including buildings classified as Satndard 1 and Class 10a in the Building Code of Australia.

AS regulates site classification, design, construction and maintenance of residential slabs standatd footings. Economical designs that avoid significant damage are practicable only if the soil moisture content of the foundation material under the footing or slab is stable or within reasonable limits of stability over the design life of the house or structure.

These changes will also see the cost of a “conventional” waffle go up as more piers will be specified in order to satisfy the new requirements of the code. Here are some of the key changes ausralian this code and how they lead to a PolyVoid designed suspended slab-on-ground being highly competitive, and a solution for problem foundations and reactive soils. This is a free 7 page sample. This latest release has seen a number of changes introduced which will in turn affect the current design calculations for residential slabs-on-ground.

This Standard gives no advice on detailing of the connection of superstructures to the footing systems for wind loads or earthquake loads. The Australian Standard has Changed. For design purposes, the life of the structure is taken to be 50 years. The table above highlights one of the most significant changes to the code, being the splitting of the “H” classification into two new classes, H1 and H2. Photo Gallery – Installation.

Because Local Authorities required professional engineer zustralian of residential slab and footing designs, I diligently assessed the structural adequacy of standard designs prescribed in AS AS Code Changes. Rudimentary engineering calculations raised my initial concern that some standard slabs were not strong enough to withstand the combined effects of static loading and dynamic foundation movement they had supposedly been designed to withstand.
