Hi again,
For that 30 story building, the negineer has used a 50% live load reduction. The National Building Code of Canada has a formula to calculate this reduction factor and the reduction I calculate comes to 78%......
Is there some empirical design formula that I may be missing here ...

Thanks,

Hello all,
My question pertains to structrural engineers refusing to show dimensions such as gridline spacing (column spacing), beam spans e.t.c...on the strucutral drawings "because these are shown on the architectural drawings".
There are SOME design standards referenced in the Building Code...
Hello all,
I was wondering if anyone knows of any good publications dealing with worm or insect holes in conventional lumber (i.e. 2x4, 2x6 studs). I am conducting strength tests to see how they compare to lumber with no such holes. The NLGA (National Lumber Grading Authority) approves these...
