@dhengr Thank you for your response, what I'm looking for is what you said by "long hand analysis". I need some design examples of doing long hand analysis on this type of bracket. Can you please provide me with some resources? Thanks. As for the grinding of the radius, do you mean in this...

@thaidavid40 I've played with the thicknesses and even lowered the loading all the way down but it seems no matter what I get small areas around where the constraints are, see this image: In my past FEM modeling experience I know unrealistic singularities can be ignored for certain cases but...

Hello all, I'm tasked to design the section of an extruded 6061-T6 aluminum side mounting bracket which will accept a 2" square aluminum tube or bar post of a guard railing. The post will be thru-bolted to the bracket using up to two 3/4" diameter stainless steel threaded rods. I do New York...

BUMP anyone have an answer for how to find actual deflection of a beam , not displacement of a node? Thanks.

Thanks for your response, that bay is actually 29' x 29' I now understand you're saying the 3.2" is net displacement from 0 that that particular joint has moved. How would I use ETABS to give me just the displacement of one particular beam due to the loading, NOT including the displacement of...

I've attached the .zip folder with the ETABS files http://files.engineering.com/getfile.aspx?folder=6eb38455-e3cd-4c38-9890-8f25e2bb4679&file=etabs_model.zip

Hi, I've modeled a 1 story building according to the plans and given steel shapes, It appears there is one problem area which has high deflection. I've attached a screen shot showing the worst deflection, about 3.2" After changing the beam section many times we've reduced it further but my...

Thank you all for your responses, I'll have to investigate the existing conditions in the field further.

Hi I have a new job in which i need to model an old existing building that is being renovated and we will be using the existing cast iron columns and red brick walls. Are these materials built into Etabs 2013? and if not how can I accurately model them accordingly? Thanks

Hi, What is the accepted compression strength of a Cast Iron column? We have a job coming up that we need to attach our beams to old existing cast iron columns. I need this information for modeling purposes. (Etabs)

Hi, I'm aware of the standard required loading on handrails and guards of 200 lb concentrated load and 50 lb/ft uniform load applied horizontally and vertically, as well as the 50 psf load on any infill material. But my boss inquired about what the increased ("Panic") load requirement is for...

Thank you, I've read the whole section and the next few, but don't see anything about structural load requirements. Such as horizontal load from the earth on the walls. Also looking for some specification about the columns and beams/girders. I confirmed the structure is in New Jersey. If...

Hi, I'm being asked to research the code requirements and design loads for an underground parking structure. I believe it will either be in New Jersey or New York. I also believe it will be 2 stories underground, i.e. 2 floor subsurface parking deck. I know there are tons of them on every...
