    Roof Bracing

    Hi all, 1) I was told that single bracings at roof carry both compression and tension loads.However, cross-bracings only take tension loads. Why might the reasons be for the difference? 2) Plus, why is a CHS a better selection for roof bracings when you have non-hollow steel rods as an option...

    How do you discern Flexible from Rigid Connections?

    Hi everyone, I'm trying to understand how to differentiate the two connections from engineering drawings, but had failed to distinguish the two. Are there typical traits you could use to determine them? Please use base connections and roof joints as examples if possible, and possibly some...

    Cracked reinf concrete centroid

    Could someone explain why it's okay and common to assume that the centroid of the cracked concrete will be located in the flange rather than the web of a beam x-section?

    AS3600 concrete elastic modulus

    Hi all, I'd like to know how elastic modulus for 32MPa of various curing day concretes can be determined e.g. 7days/ 14 days/ 28 days/ 30yrs Is it okay to assume that because creep and shrinkage effects are so miniscule in 7 , 14 and 28 day concretes, modulus of elasticity are taken as...
