How can I solve the reactions for a portal frame that has fixed bases, it's height is 14ft, its width is 10ft, and the applied nodal load is 7.75k applied at the top left corner of the portal frame?
I would like to calculate the shear, axial, and moment reactions at both bases. I am confused on...
I don't think REVIT is a good software for shop drawings, I also think that 2D is dying out as 3D is taking its place. 3D is possible now since computers are much better. The reason I don't think REVIT is a good option for shop drawings is because it lacks detailing capability. I think a better...
I got asked a question recently that just threw me off. The question was three lines long,
PGA = 0.3
S1 = 0.9 (I think S1 was 0.9, but I don't recall exactly what the value was)
Find PGAm?
I know PGAm can be found using section 11.8.3 from ASCE 7-16 but the factor Fpga, is based on the site...
My thoughts are that you can compare it, in terms of shear, to a concrete beam without reinforcement. Concrete is a brittle material yet it has its own shear capacity and definitely needs reinforcement to help with tensile forces. I think your case is similar. I would make sure the beam has...
Hi,
Talking specifically about section 12.3.4.2 in ASCE7-16 "Redundacy Factor, rho for seismic design categories D through F" condition b. the last part which states "...The number of bays for a shear wall shall be calculated as the length of shear wall divided by the story height or two times...
Hi,
I am wondering if the site class can be identified from the PGA for a specific site or the site Mapped Acceleration Parameters Ss or S1? If so, how?
Thanks,
I am trying to find a nailing pattern for my 5ply 2x6 built-up wood column. According to NDS 15.3.3.1 b) all nails have to penetrate all my laminations and at least 3/4 of my outermost lamination. For my 5ply wood column the nail should have a length of at least 7.125" but the maximum size of a...
