    Elevator Rail Stop Analysis

    TXStructural et al: Here is an excerpt from the email forwarded to me: Attached is one of the photos he sent (And, yes he sent a photo of a photo on a cell phone). Maybe it will look familiar to somebody. This is everything I had to work with. In Russia building design...

    dowel spacing question

    Appendix D of the ACI 318 on anchorage will tell you what you need to know. Powers and Hilti have free design software for adhesive anchors and they work very well (I like the Powers one, myself). In Russia building design you!

    Elevator Rail Stop Analysis

    chicopee: I do not know how that helps me at all. I am instructed to perform these calculations. Are you suggesting I say that I say "no" to this? EIT's are somewhat at the mercy of their project managers. Besides, even if I were to say, "I don't feel comfortable performing these calculations."...

    Elevator Rail Stop Analysis

    I found ASME 17.1 2007. There was no mention of the specific procedures related to rail stops when testing the hydraulic system. I only noticed the requirements for the mechanical devices to be used in service. In Russia building design you!

    Concentrated Load (Partial Loading) on Slab

    Sort of does. In Russia building design you!

    Elevator Rail Stop Analysis

    dhengr: Why don't they have a standard detail? Who knows. If they did, they wouldn't be asking us to analyze it. The 125 fpm velocity was what they wanted us to analyze it for. They performed a previous test of the stops at a much lower velocity, i.e. that assembly with the 3/8" is already...

    Structural Integrity Assessment

    Good catch. I'm curious now. In Russia building design you!

    SST Twist Strap at Every Roof Rafter?

    My point was that full dead load can't be subtracted from wind load. I was using ASCE 7 10 as an example. That applies regardless of the new wind codes. In Russia building design you!

    Elevator Rail Stop Analysis

    I haven't looked at that publication. I agree, something is suspicious about that force value. We were told this was a temporary stop for testing equipment. Would that be applicable to ASME A17.1? I'll have to take a peak at it if I can find it. In Russia building design you!

    Does exposed wood framing covered under porches and canopies need to be treated?

    We limit untreated lumber to be contained within conditioned spaces only. In Russia building design you!

    Post-fire framing evalutation

    Thanks, guys! In Russia building design you!

    Bridge Inspector Career

    Agree with bridgebuster. If you REALLY want to switch, your chances of being recruited will be slightly higher if you try employment at a DOT office. Private firms with DOT contracts aren't going to be as forgiving with your previous experience. In Russia building design you!

    Structural Integrity Assessment

    If you are saying you have no experience with condition assessment of structures, then I do not recommend reading a book as a reference. I recommend getting a mentor who is experienced in structural assessment - and maybe using condition assessment books as a reference when you are experienced...

    Drift Limit for Free Standing Sign

    I agree with Crackerjack - AASHTO or your State DOT is going to be your best bet (hint hint: DOT's tend to give out their standards and spec for free via their websites). On a side note: Remember that damaging adjacent components, e.g. cladding, is a major part of limiting deflection. Unless...

    Concentrated Load (Partial Loading) on Slab

    I am not in a Eurocode justification, but I can try to walk you through the concepts. Is it a structural slab or a slab-on-grade? In Russia building design you!

    12 x 24 Wood beam 1940's +/- cracking in many places. I would like to know about epoxy repairs.

    It can be done if need be. You need justification from empirical data from somewhere (manufacturer, university/government study, etc.) that quantifies the bond strength to the wood. Manufacturers of structural adhesives (>400 psi bond strength) will tabulate allowable bond stresses for APPROVED...

    SST Twist Strap at Every Roof Rafter?

    RareBugRA: Don't forget that the general load combination for uplift is .6D+.6W for ASD and .9D+1.0W for strength. Not allowed to rely on 100% of DL. In Russia building design you!

    Elevator Rail Stop Analysis

    Have a bit of an unusual little project to analyze elevator rail stops, which are used as a barrier for the elevator techs to test the pressure in their hydraulic system. Attached is my analysis attempt. It is the impact analysis only, not the analysis of the connection strength. Any critique...

    Bridge Rating

    They sort of are. They have amassed a collection of the most typical legal and permit trucks, varying from dump trucks to AT cranes (design trucks included as well). I was not involved with that part, but I think that the Office of Structures collaborated with Hauling Permits to get some of this...

    Bridge Rating

    The state I work in is performing a comprehensive structures load rating. The Policy and Procedure Manual outlines the basic guidelines for how they want things to be done. They specifically are mandating that LFR to be performed on all bridges that were designed with either LFD or WSD. Only...
