Hi everyone,
My company is investigating the failure of some roof framing after the recent snowstorms. The rafter does not connect directly into the wall plate. Instead the joists bear on the wall, continuous 2x4 runs across the top of the joists and the rafters bear on the continuous 2x4...
Hi everyone,
I am a P.E. working full time at a good company that will allow me to work on the side provided it doesn't interfere with my regular work.
I recently have been contacted by a rigging contractor to design and certify spreader beams in my free time. I have experience doing this and...
Hey everyone,
In a few weeks I will be starting a new job at a firm that designs exclusively in prestressed concrete. I have never dealt with prestressed concrete before but am eager to learn all I can. Does anyone have a recommendation for a good textbook/design guide?
Thanks in advance and...
Hi everyone.
I am a structural engineer but have been working at a mechanical firm for years. When things get slow I sometimes work on the Mechanical side under the direction of the MEs.
I have been working on a clamp design governed by ASME Section VIII Div 1 Appendix 24. By code I am told...
Hi everyone,
I have seen some job openings recently that require knowledge of STAAD. I have not used STAAD but am competent using RISA 3D and Solidworks Simulation as I have been doing so for years on large, complicated projects. I was wondering what differences there may be that would be a...
Hey everyone. I hope someone may know the answer my questions. What can a civil-structural P.E. stamp in Louisianna? What is the real difference between what an S.E. can stamp and what a civil-Structural P.E. can stamp?
The reason I ask is once I made a phone call to the Board of Engineers in...
Hey guys. I am looking for a good book on the design of steel buildings such as large wharehouses. I know the basics of steel design but have never designed anything much larger than a moment frame or small steel addition. I have the steel design book I used in college but I am looking for...
Hi everyone,
I am analyzing loads on a structure while it is being transported on a truck. This is a manufactured item that will barely be small enough for a truck transport. I know how it is planned to be positioned and held down. I will be using RISA 3D for an analysis. I would like to know...
I heard that in some states you cannot practice structural engineering unless you passed the Structural I and II PE exams. Other states allow you to practice as long as you have a PE and are competant in the field you are practicing in. Which states require the Structural I and II?
I am working on a RISA model in which spring constants need to be used in my boundary conditions. The spring constants I am recieving from an outside source are given as radial and tangetntial stiffnesses due to the cylinderical shape of the structure. As far as I can tell RISA only works in the...
I have a client that wants me to model a large structure in solidworks and run analyses on the entire model with simulation. They want the solid model to be used in simulation with 3D meshing (no surfaces). Parts of the model will be very large (1000's of square feet) and very thin (<1" thick)...
I am analyzing an existing small steel structure used as a work area for pipe welding. The sides of this "habitat" are plastic curtains and the top is plywood. The entire structure is located inside of a building and will never see wind loads. It is even supported by wheels so that it can be...
