    Crazy cantilevered steel deck

    You guys have it good if the residential market pays this much. Not the same can be said in Australia. I've seen fee proposals for full structural documentation as low as $1K (+gst) for a single dwelling, 3 bedroom house.

    Whats the ball park charge in fees for a residential project if you are making an allowance for multiple no. of inspections as you have mentioned?

    Crazy cantilevered steel deck

    DL = 0.198 / 0.61 = 0.32kPa, deck is probably around 0.2kPa. Its probably a touch higher than 0.5kPa but not far off. Where I practice LL of 2kPa is sufficient for a balcony in a self contained dwelling such as this. Balcony LL of 4-5kPa is for commercial type building or a multi-occupancy...

    Crazy cantilevered steel deck

    Well it works, until it doesnt. Hopefully nothing bad happens. A good case and point on why its hard for a common person to judge what is engineered well and what is not, just because it looks 'nice' and 'well built' doesnt mean it was constructed with good engineering. Hope this message...

    Crazy cantilevered steel deck

    I couldnt read the details on the bolt. Hopefully they are 20mm dia, those usually work around 60kN if edge distance is at least 100mm. Wish they could record a load test on it. install a spa/tub fill it 200mm with water, see if it works. He could title it "pushing the bounds of engineering...

    Crazy cantilevered steel deck

    Crunching some numbers based on his drawings: Width = Joist at 600mm cts x 8 = 4.8m Length = 2.5m assume DL = 0.5kPa, LL = 2kPa Design UDL = 1.2 x 0.5 + 2 x 1.5 = 3.6kPa Max Moment per column = 3.6 x 4.8/2 x 2.5^2/2 = 27kN.m Column: 200SHS Tension on each anchor bolt = 27/0.2 x 0.5 = 67.5kN...

    Concrete Column - cold joint cracking

    I have actually have seen worst, this isnt that bad. You can try and fix using grout (or other retrofit solution) then finish the column with plaster or something similar (to provide secondary protection). Obviously, you still have to assess the design stress where the crack is located. Its...

    750 AUD per year for Engineer Australia membership. Is it a joke?

    I see exams as a way to filter engineers who are competent enough to take a project alone and who arent (i.e. structural engineers doing buildings must be able to size/frame buildings and come up with practical structural designs/solutions). A good setup is the IstructE exam where questions...

    750 AUD per year for Engineer Australia membership. Is it a joke?

    Exams arent perfect but they serve their purpose. Example, you can pass your concrete design subject without completely understanding how long-term deflections are calculated because its only <20% of the curriculum. In real life this isnt acceptable, if your structures fail in one critical...

    750 AUD per year for Engineer Australia membership. Is it a joke?

    To add more damage, there was already an existing regulation in Victoria for engineers doing work in the building construction industry, this did not change. However, they changed the registration part, and took in a whole new level of stupid complexity (previous system was simple). All...

    750 AUD per year for Engineer Australia membership. Is it a joke?

    NZ please dont. Regulation of engineering in OZ is currently a circus. Governments are rolling out regulation to appear that they are doing something in improving the industry. Meanwhile, the regulations in place are drafted by people who probably never worked in construction or building...

    Calculation of crack widths in foundation design

    But isnt there an ACI doc for liquid containing structures that specifically limits crack width to address durability?

    750 AUD per year for Engineer Australia membership. Is it a joke?

    Yes, EA can charge this much and its because of one word: Apathy. Last time I checked most Australian Engineers only concern themselves with their own projects and invoices. Not the state of the profession. Not legislation around engineering. Not even their own pay. We are just too busy minding...

    Artificial Intelligence in Structural Engineering

    AI is good for looking up information and probably engineering computations. Hope it becomes so advanced someday that it can go on-site and have a cordial discussion with bob the builder and frank the architect on how to 'make the engineering work' on whats been built on site. I'd be more than...

    Telling People No

    Steps I take as follows: 1. Try to explain in simple terms why proposed solution will not work. 2. Try to supplement this with risk vs reward discussion. Most GC appreciate this because if anything goes wrong after construction its usually the GC who is asked to fix a defect. 3. If they still...
