Hi, I'm trying to find information on how residential properties in Australia are designed to be 'flood resistant' if part of the structure is below the PMF level and is required by the local council. I know the bridge code AS5100 has information on how to calculate loads from moving water...

Thank you both. Couldn't agree more with what you've both said. I guess the question begs if you're adding more than say 10-15% loading and you're not on rock. If I assume that a Geotech Investigation verifies that the bearing capacity is sufficient, though I'm on a highly reactive clay or...

Hi, I've got a project where my client is wanting to add an additional storey to a single storey house. The building is from the 1920's in Sydney and is constructed as Sandstone footings (approx 400mm wide solid blocks) and then timber framed floor, with double clay masonry external walls...

By the way, I do like the idea of adding bedding reinforcement to get a better than 45 degree angle of dispersion. Perhaps that's something to add in regardless? Not sure how easy it is to apply to existing?

Thanks for your comments guys, Perhaps it is better to use a live example of a project I'm currently looking at.... The building was built in approx 1950's to 1960's as described in the first part of the thread and my client wanted to investigate a couple of options. Upon calculation, the...

Thanks Agent666. That's very helpful. I suspect that in NZ due to seismic activity that your usage of masonry for load bearing elements is quite limited, however the principles for determining basic compressive strength for Mortar and Clay masonry should be somewhat universal. The scratch test...

Hi All, I'm in Australia and I'm currently trying to justify a significant concentrated load applied from a steel beam to a 110mm thick existing clay masonry wall. The building was built in approximately the 1950's-1960's and is vertically supported and laterally stabilised by many 110mm...

Hi Enable, Thank you very much for your thorough response! And apologies for the delay. I've been on a break. I think that approach seems sensible for me and was in alignment with my thinking. Thanks again! Ben

Hi All, I've recently migrated from Large commercial Structures to small residential structures and I have come across a few different properties recently where a sub-floor series of Brick piers supporting tiber bearers & Joists above are not founded on a concrete pad footing, but rather just...
