Thanks for the reply Josh. I was looking at chapter 7 of DG11 previously to see how much work it would be to model the floor. We have a few ETABS licenses, I was excited when I saw they added the new DG11 analysis, but unfortunately I think it uses steady state cases which requires an ETABS...
I'm wondering if anyone could provide some help on a question I have regarding floor vibration and Design Guide 11. I have a steel framed floor, all beams and girders, the beams are all 33 feet long but I have different length girders depending on where I am in the building. Some girders are 33...
So ASTM E1300 would be using a 3 second gust for calculating wind pressure? In that case I would need to convert my hourly wind pressure to a 3 second gust wind pressure in order to use the charts in ASTM E1300.
I'm wondering if someone familiar with ASTM E1300 can provide a little help with some double glazed sealed glass unit design (curtain wall). I'm in Canada and we typically design glass to CAN/CGSB 12.20. In Canada we use average hourly wind velocity while the US (ASTM) uses 3 second gust. I...
I know I can go into member 4 end releases and release the moments on M1 but isn't that the default for a pinned joint? Also I thought that would cause an instability because I'd have a pinned boundary and an end release on the same joint. I think I uploaded the wrong model; this one shows the...
I'm really new to RISA and I'm fumbling my way around. I'm trying to model a somewhat strange balcony supported of the side of a building. The balcony has a angled rod hanger on one side and a continuous cranked (in the XZ plane) channel framing back into a channel ledger on the building on the...
Yeah I have gone through the calculations and I have a fairly good grasp of it, I was curious how people typically deal with them since the calculations are pretty time consuming.
Is the floor area very big? You could add beams between the existing joists to essentially cut their tributary width in half. You get into some trouble with joist bridging and bracing the top flange of the new beam but that's what I usually try to do. I never mess around with joists, their...
I was wondering if anyone here knows of software to design steel plates embedded in concrete with nelson studs or even some good literature? I'm looking for something that would use the Canadian codes but if not that's okay. Just seems like topics like these get left out of the codes as they...
Sounds great.
Yeah I forgot to mention the hook is for fishing bluefin tuna which can weigh a lot (1496 lbs is the record) and they put up quite a fight.
Thanks guys
Not sure if this is the right thread for this.
A friend has asked me about bending 3/4" 304 stainless steel round bar. He has a bending machine but the time it would take to get the new dies would be too long. Cold bending by hand is too hard so he wants to heat it to accomplish the bend (3"...
