nice! thanks azcats. I guess torque typically applied in the nut end. I didn't know that! And the DTI can be applied on either ends of the fastner. Thanks for all your help! Good Day! Cheers, Jeff

Hello Gents, Just a basic question, I am trying to connect modular platforms with 5/8" A325 bolts with A194H nuts. There will be a flat washer on the nut end and a direct tension indicator on the head end. Just wondering if it is ok to apply the torque in the nut end? I assume not because the...

Thanks for all your advice. Structure would be attached to skid mounts and I'm guessing that those skid mounts are anchored to the concrete. @slta, I am familiar with some code such as ASCE and AISC, however not familiar with every type of structure... I have a grasp of the general aspect of...

Gentlemen, Here are some examples of what I'm talking about. The support is basically welded onto a box frame made of wide flanges that rests on the ground. examples attached. http://files.engineering.com/getfile.aspx?folder=1d45470c-c997-4629-b7e0-0d630c2fd601&file=example1.JPG

Hello, I work for a mechanical company that produces recycling equipment. A coworker of mine designed a support frame for a compressor and asked me if there was any code that allows him to build it without anchor bolts. He wants to know this because the client will be relocating this equipment...

PMR, you make a good point. I can always make an intial design for ABC and continue, if my company allows, to design for DEF later on the future.

I'm trying to design a platform that will used by employees to divide outlying trash from conveyors. I have taken into your considerations of classifying the knee-brace system as OMF and have verified that in AISC SP C-11. Therefore my R=3.5 per ASCE 7-05 chapter 12. The thing is, I'm using...

Thanks for your quick responses jdge. The platform is for recycling plants. These recycling plants can be located anywhere in the world... I've classified them under occupancy category I. I guess I can tell my boss that this platform is to be only located in areas with SDC =A,B, or C ??

My structure is a platform that is 17 feet high. It has knee braces in all directions. Can I justify by using R=3 due to ASCE 7-05 that the structure is not specific braced frame?

Hello, Just wanted to verify with someone, I designed a structure with R=3 for seismic base shear. Does that mean I do not need to follow AISC seismic provisions? I overheard from someone in this forum where they mentioned if R=3 or less AISC SP doesn't apply. Where is this noted specifically...

Thanks JAE and jdgengineer. Yea, I remember using ASCE 7 for calculating the base shear for this matter. I just wasn't sure of what a conservative SDS value was. During school, I've used SDS values close to 1.0g for downtown San Diego. Appreciate the help!

Hello, I'm designing a 1-story platform that can pretty much be located anywhere in the world. As a rule of thumb, I was informed to use seismic load of 40% times the Dead Weight of the structure. There will be cases where there is/isn't earthquake (50-50). Since there are no PE's in the...

Hello all, I have two questions I'd like some advice on. I hope with your expertise I can work through these columns! I am just a junior structural working in mechanical industry with no senior mentors. Scope of the story - platform design was outsourced by a FEA company and they made our...
