i'm doing some townhouses which will be using hebel flooring. Since hebel is heavier than structafloor i'm guessing that there would be a different load for calculating lower floor studs and lintels. i do not know if there is a separate table for that or a program. So the question is, How do I design the lower floor walls?
The span tables in AS 1684.2, Residential timber-framed construction, assume an upper storey floor load of 40 kg/m². However, various software programs allow you to input different floor loads. You will find a range of software programs on our website here: https://www.woodsolutions.com.au/resources/specifications/span-tables-and-software. For example our Timber Solutions software allows the user to input various upper storey floor loads. According to this website https://empowerconstruction.com.au/blog/what-is-hebel-powerfloor/, 75 mm Hebel PowerFloor imposes a self-weight on the substructure of 52 kg/m².
I have just discovered your website and have been doing some in-depth research into your brand, and to say the very least, I am very thrilled to have found you. More to the point, I am currently in year 11 undergoing "Stage 2 AIF". The subject is similar to "Research Project" but slightly different in terms of gathering reliable sources. I am emailing today, to hopefully receive some much needed feedback and recommendations. If you could please assist in giving some feedback on these questions, your time would be greatly appreciated. - For my task I have chosen to plan, design, and build my very own wooden coffee table, using sustainable methods. Could you suggest any key methods I could use to keep my assignment sustainable? - I am currently In the designing phase, and trying to come up with a final design due to not fully understanding structural stability and aesthetics. I am well aware this is your strong point when it comes to woodwork, so I would love for you to supply me with some table design tips and some possible features I could add.
We were pleased to hear of your very practical hands-on project. No doubt you will be using some kind of hardwood for your coffee table. With regard to sustainability, our Environmental Product Declarations (EPD's) provide helpful data. You can download them from our website via this link https://www.woodsolutions.com.au/resources/publications/environmental-product-declarations. EPD #2 deals with Australian-grown hardwood and other EPD's deal with softwood, plywood and other wood products. For a more in-depth look at Australia's forests you could refer to the Government's State of the Forests Report available here https://www.agriculture.gov.au/sites/default/files/documents/Australias_State_of_the_Forests_Report_Synthesis_2023.pdf. Regarding the design of your coffee table it's important that the tabletop is allowed to move a little in response to changes in moisture content. You will find information on attaching tabletops in such a way that the wood can expand and contract on this website https://www.craftsmanspace.com/woodworking-joints/17-ways-to-fasten-a-tabletop#google_vignette. Finally, the finish needs to be a type of coating that will resist spillage and can be easily wiped clean. Oils and waxes are not recommended, but a satin or matt polyurethane provides a hard-wearing finish that brings out the natural colour and grain of the wood. Good luck with your project.
I am learning the timber structure design on your website and I found it very useful on all the timber design. When I was running through the timber system in the guidance WS TDG 46 Wood Construction Systems 11-20 I found there was no sample CAD file and project files on the work samples from page 138 that I think it would be difficult for me to follow. Therefore, is there any chance that you can share the CAD and project (e.g. PDF) files so I can follow the instructions and procedure of how to work out the examples.
Unfortunately there are no CAD files for our Technical Design Guide #46. The worked examples are “general conceptual designs” as explained in the Introduction, and are provided to show how to calculate using various design inputs, rather than for use in real life scenarios where actual design drawings would be needed.
