Hi, I am a civil PE who changed career paths shortly after getting licensed. I've only renewed my license once and I was grandfathered in because I just passed my PE exam. As I mentioned, I've switched career paths and structural/civil engineering is not directly related to the day to day...
Hi,
I am getting familiarized in using Risa 3D for plates and it got me wondering. Can I use plates to analyze beams? Specifically, I am interested in modeling a plain concrete beam in bending with a distributed load. This will allow me to compare my results to those obtained from beam theory...
Hi,
I am determining the wind load on a "trussed tower" using Chapter 29 of ASCE 7. Equation 29.5-1 provides a resultant wind force in pounds, but I was expecting a pressure. Furthermore, it states that qz is the velocity pressure evaluated at height z as defined in Section 29.3, of the...
Hi,
I am not sure what the technical term is, but I am curious if anyone has experience with bolting an eye-bolt through the web of a channel.
We are trying to find a tie off point for someone which needs to be rated for 5,000 lbs. We have since decided on a different option, but one of the...
Hi,
I am studying for my PE exam and I stumbled upon this issue and I cannot wrap my head around it. Can any of you please provide some guidance?
The MSJC-11 Section 1.9.6 defines the Effective Compressive Width Per Bar as the least of:
a) Center to center bar spacing
b) Six times the wall...
I am curious if anyone has any experience or knowledge regarding the effect that construction marking paint applied to non-epoxy coated rebar might have on bond strength (i.e., development length). Specifically, we are constructing large, circular foundations that require personnel to walk on...
Hi,
Does anyone have any experience on using Caliche for a road base material? Our contractor is proposing the use of this material, but we (as the owners of the project) are not familiar with it.
The project is in the pan handle of Texas and our company is based out of Minneapolis, MN. We...
Hi,
Does anyone have any experience with using maintenance free bolting solutions for either wind turbine foundation or tower bolts? An example would be the IHF Stretch System as detailed at the following link...
My company is currently constructing a wind farm next to one of our existing wind farms. My question is about the foundation anchor rods. The rods are typically #11 Grade 150 threaded rods (different turbine types may use different sized bolts such as #10, but that is not related to my...

Hi, as discussed in the referenced thread above, ACI 318-11 specifies that circular ties in a compression member shall over lap by at least 6" and terminate in a standard hook that engages a longitudinal bar. My question is, what is considered "engaging" a longitudinal bar.
If...
As I mentioned in my title: I thought wet setting anchor bolts was bad practice?
We are building drilled piers (30" diam. X 20' deep). There are four anchor bolts embedded in the center of the pier. The anchor bolts are 1" diameter by 2.5' long, headed anchors. The sub contractor...
