Hi guys I would really appreciate some advice here. I would like to start a small business as a sole trader. My intention would be to do only engineering reports on existing buildings and potentially also some forensic type reports on failures (if I am lucky enough to get this far). I am...
My understanding is that thermal stresses in a slab on ground are produced by a temperature difference between the surface and the underside (I have seen this referred to as a thermal gradient). Uniform heating through the section does not lead to tension in the steel as the coefficient of...
Hi, I am looking at an external concrete slab on ground.
Can someone tell me what would be the likely thermal gradient through the slab depth?
Also is the thermal gradient generally a constant value or does it vary significantly with the slabs thickness?
Thanks in advance.
Hi I am looking at some formulas which give lateral pressure distributions on retaining walls for point & UDL surcharge loads. The formulas do not reference Ka or K0 (AS4678 figure J7) or suggest how to modify these pressures for different Ka / K0 values. Does anyone know where I can find...
