Trying to determine the best method to issue plans to contractors for bids? Current method is to publish an ad for public projects and send out a mass email to all the reputable GC's in my area. Is it old school for me to want to control the distribution of the construction documents and any...
An architect sent me the pictures below, they are wanting to construct a small light framed dog house type structure on to an existing building to add some curb appeal. There is a mod bit flat roof on the other side. Age of building is not known, but appears to be around 60 to 70 years old. I"m...
Has anyone here ever used GatorBar or heard of GatorBar being used in lieu of steel bars? If so what is your opinion of the product?

I'm working for an Architect and on one of his previous jobs the concrete stairs at the entrance of the building is cracking. I was not the engineer on the job but on the worst crack it appears there was no steel in the stair nosing. For the other flaking type cracks I'm thinking there was to...
I'm designing a pipe bridge to span from a tank farm platform to a process building. Wanted to see you guys thoughts on a sliding connection with teflon bearing pads.
Info...
The bridge is two truss members built up with double angles and braced together. Top chord bearing
Bridge span ~50ft...
What would you guys say is the EOR responsibilities for a double tee roof system? Particularly the connection design to a tilt up wall for diaphragm loads and out of plane wind loads on wall.
How would you go about connecting a structural foundation supported by piers for a new building that ties into an existing building with a slab on grade foundation. I would prefer to allow the structures to move independently but that could get ugly with doors and corridors crossing the tie-in...
I have a cantilevered concrete beam that supports a perimeter concrete beam and column next to an adjacent foundation. I cant find a good example to reference back to for this condition. Attached is a concept of how I was thinking it needs to be done. Just wondering what people's thoughts are on...
Does anyone have a link/document that outlines the major changes from ACI 530-08 to 11? I have the 08 and taking the PE exam this Friday and just noticed there are some major changes...lol maybe should have thought about this earlier but o well.
Will be taking the PE exam soon and was wondering if anyone knows where I can get a pretty comprehensive list of moment diagrams for frames? Would like to quickly be able to determine max moments on the frame, reaction values and deflections assuming "I" is known.
Can you use Risa3d plate tools to accurately model stresses in a member, such as a column and base plate interaction? I have modeled a column section and base plate using plates. The stresses calculated look reasonable. Just wondering how accurate risa is being used in this manner and if anyone...
I have a situation where a cantilevering beam is supporting a perimeter beam/girder. See attachment.
Does having the perimeter beam be continuous pass the supporting beam with a splice a couple feet away from the supporting beam put eccentricity into my double angle connection? I think not but...
I'm designing a roof system that has horizontal x bracing to carry lateral loads from wind to braced frames. This puts compression in my roof beams. Economically my beams can not meet the KL/R limit state(compact shape doesn't work for roof deflection). I have bar joist bearing on the beams at...
