Here are some of the key changes to 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. Some of the reinforcing requirements for design have changed and have the potential to have a significant affect on the cost of a waffle slab.

Where relevant, once the appropriate Site Classification has been assessed, CMW can design the minimum thickness of sand pad, or alternative measures that may be required to reduce the severity of the Site Classification.

Welcome to my engineering blog The previous code revision called for reinforcing mesh to be upgraded to the next specification when a concrete slab was greater than 25 metres in length. 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. We were unable to find this edition in any bookshop we are able to search. Your email address will not be published. More Code Information To understand more about how the changes to AS may affect your slab designs and consequently, slab costs, contact your engineer.

Check copyright as2807 Cite this Title Residential slabs and footings. 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. A soil's Ys rating is its indication of movement potential. CMW Site Classification Because Local Authorities required professional engineer certification of residential slab and footing designs, I diligently assessed the structural adequacy of standard designs prescribed in AS For more information about ASclick here: AS and AS Supp. 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.
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 staandard a waffle slab. These online bookshops told us they have this item: Language English View all editions Prev Next edition 3 of 5. The Site Classification is related to the clay content, plasticity and inherent reactivity of the soil. Separate different tags with a comma. Steel Reinforcing Calculations Some of the reinforcing requirements for design have changed and have the potential to have a significant affect on the cost of a waffle slab.
