You hit it right. The rod was spaced no more than 9 feet and the rod was tightened with steel sleeve (bolted). The calculations were passed and checked by SE licensed engineers. Thanks.

Yeah, I guess I got a little sensitive when he mentioned the people I worked with. I should of explained in the beginning that their are anchors on the sides and back of the canopy, and a beam at the middle. When it got checked the first time, they gave me a list of members to analyze. It was a...

MGX, Thanks, thats a good direction for me to focus on. McEngr, Always good answer. dakota_79, Lol, ok. I have a feeling this was for the canopy question that I previously posted.

dakota_79, Ok, that wasn't very nice, I appreciate you participating but you're nitpicking a little to much. My main goal was to find a direction for the rods. And my intention was never to reveal everything. My calculation was checked by more than one license engineer and they gave me a list...

Man I'm going to sound like a little kid for asking this question. What do you guys think? I'm curious, what is a decent Structural Engineer to you guys? Limit it two answer, dont say he needs to have strong eduction, strong experience, unlimited resources, have all the licenses in the world...

dakota_79, I don't really want to go into detail, but the rod is covered by 1-3/4" or maybe 1-7/8" steel to limit the vibration and amplification (if I remember correctly). The weight of the canopy is pretty heavy, furthermore the sides and back of the canopy is anchored to the wall. The...

I also change the spacing and added more rods. Thanks for the help.

I used chapter E.

Yes, its slender. The rod is 9.6 feet long. The drawing shows that they decided to cover it using a hot dip galvanized steel tube, the steel tube is about 9' long. I'm not sure if that is just for aesthetic design or so that it wouldn't exceed L/r (300). But anyway lets say that slenderness...

I'd like to think of it as a good start. ipswitch, how big is you're collection?

The canopy is 51'x10', the 3/4" threaded S.S. rods are connected at the top end of the canopy. there are four of this rods. At the other end of the canopy, a 6"SQ. HSS is used as a support. When there is an uplift force, the rods are going to be under compression. I have never checked a rod...

Thanks for participating daedalus34r, If you can, can you tell me how in-depth do they cover seismic and wind analysis? And what you found the most important subject covered? The way I'm learning now is based on what the engineers says to me, and what I read from the collection of books and...

McEngr: Thanks, I needed that kind of answer. And I made up my mind. I will work for 1-2 years and then go back and get my master. I think I can do it, I mean I don't plan on having a family of my own until I hit my late 20s and early 30s. ipswitch: "I have a Master's in Structural. I've...

When calculating for the uplift load, do you take into consideration the weight of the roof? I'm not sure if I should subtract the weight to the uplift load. Should I not take the roofs weight into account to maximize the uplift? I think I was looking at Alan Williams book and he subtracted...

ipswitch: Thanks for the advice.
