What I have is an acrylic and glass enclosure. I believe the inside will be temperature controlled, but the outside of the wall and roof elements will be exposed to the temperature. I need to provide the thermal movements which will be easy for the roof elements, but the wall elements will be a...
I am working on a project where the project specifications state the following:
Thermal Movements: Allow for thermal movements from ambient and surface temperature changes. Base calculations on surface temperatures of materials due to both solar heat gain and nighttime-sky heat loss.

This connection occurs at a pipeway framing plan in an industrial plant and due to the lateral forces induced by the pipes a torsion is induced at the ends of the beams. There is grating that bears on the top of steel so a flange plate would not work. I would be concerned about connecting the...
hokie66 - The problem is that most EOR don't want the responsibility and most don't have a full understanding of connection design based on many conversations and also working in a structural engineering office. This request by the EOR is a great example of why this EOR should not design the...
paddingtongreen - The beam web was actually one of my concerns, but I need to talk to the EOR about the beam web itself. The requirements for this project keep growing exponentially!! I agree that the beam web will not be able to resist much torsion if any at all. I still think that the angle...
The beam has torsion and vertical shear. The connection that they are wanting to use is a double angle connection that is bolted to the beam web and bolted to the girder web. How do you suggest resisting the torsion in this type of connection?
The EOR has requested that I provide a calculation showing the torsional capacity of a bolted-bolted double angle connection between a W8 beam and a W8 girder. My thought was to resolve the torsion through bolt tension in the bolts on the beam side. My concern now is how I design the angle leg...
ishvaaag,
The way the landing is constructed is that the rebar is welded to the fins and then the concrete slab is placed. A cross section of the landing is as follows:

I have a 2-1/2" concrete slab that spans between fin plates at a stair landing. The fin to fin spacing is 21". There are #6 reinforcing steel bars that spans between the fin plates and are welded to the fins with a 1/4" fillet weld all around. The reinforcing steel bars are located mid-depth of...
Yeah, I am reading "Guerrilla Marketing for Consultants" and it states that cold calling is a waste of the client's and consultant's time. The last 3 years have been great, but I spent no time marketing because I was so busy. I am feeling that was such a huge mistake. So I am sitting back and...
Just wanted to get some feedback on what people have had success in marketing a specialty structural engineering firm. I have about 6 to 7 clients at this point, but would like to expand that to about 10 to 12. My firm provides structural engineering services to steel fabricators and...
