    Post fatigue design - luminaires and traffic signals (LTS-6)

    Hello, I ran into a problem while doing a fatigue design check for a post groove welded to a base plate and appreciate any guidance on this matter. In LTS-6 chapter 11, it gives you scenarios on how to solve two factors, finite and infinite life fatigue stress concentration factor(K_F and...

    Section modulus of single angle about major/minor principal axis

    Yes, I tried the calculator and was able to find the moment of inertia for the principle axes. However, I'm having a hard time determining the distance as you mentioned. For the geometric axis: Sx = I/(y-x_c) How would I find the equivalent distance of (y-x_c) for the principle axes?

    Section modulus of single angle about major/minor principal axis

    I need guidance on how to calculate the section modulus of a single angle 2x2x1/4 about the major/minor principal axis (theta = 45 deg). Any links/worked out examples would be amazing. Thank you

    Connection between drag truss and post

    JAE Yes, this is a wood structure. My boss drew a plan that had a drag truss laying on top of a 7x7 wood column at both ends and told me to calculate the drag strut force which I was able to do. However, I'm not so sure about the connection to the columns. Am I supposed to calculate the uplift...

    Connection between drag truss and post

    Hello, I need help coming up with an adequate fastener between the drag truss and the posts supporting it. After calculating the drag strut force, it comes out to be about ~4500 lbs, and it's being supported by a 7x7 post each end. The drag truss length is 36.25'. How would I go about...

    50 feet cantilever pole footing design

    Hello, I'm hoping for some inputs to see (or guide me) if I'm going in the right direction. I have a 50' cantilever pole with a base diameter of 30" and tapers up to 15" at the top and is located in a zone with 100 mph wind speed. I'm using AASHTO Structural supports for HW Signs Luminaires...

    Glulam wood beam to steel HSS column connection

    Hello, I need some guidance on what connectors/bolts/weld to use to connect a 6-3/4"x34-1/2" glulam beam on top to a HSS 7"x3"x3/8" column as support. I usually use a Simpson PCZ Post Cap when it's a wood beam on top of a wood post but I'm not sure if the same connectors can be used for wood...
