    Response Spectrum Analysis - Scaling for building with non-orthogonal SFRS - NBCC 2015

    Apologies I didn't give any context. My RSA shows a larger base shear than %80 of the static base shear from the code. Based on the period of the locked RSA, I was able to use NBCC 2015 Clause 4.1.8.12.(6) to apply the 2/3 cutoff and scale back my base shear in my model to 90%. This still...

    Response Spectrum Analysis - Scaling for building with non-orthogonal SFRS - NBCC 2015

    I have a building where approximately 50% of the structure is rotated 15 degrees. I am using a response spectrum analysis in accordance with the National Building Code of Canada 2015. The building is a structural steel, braced frame building. Normally I would calculate the base shear using the...

    NBCC 4.1.5.2 Uses Not Stiplated - Live Load determination

    Thanks for the input all. Based on your input, i beleive the confusion is that the reviewer is assuming that the live load includes the weight of the equipment itself. I will put together a diagram showing all the dead load of the equipment, live load on equipment, and live load due to occupancy...

    NBCC 4.1.5.2 Uses Not Stiplated - Live Load determination

    The information below is based on the National Building Code of Canada 2015: I have a plan checker rejecting drawings due to inadequate live load. I have designed a mechanical platform using 3.6 kPa of live load, but he is saying that it should be 4.8 kPa unless it is shown that the live load...
