    Wood post Cracks

    The column size sounds way too big for a deck. Also, the larger the column the higher the probability of checks presence. 100 psf LL for a residential balcony seems a bit excessive. Per ASCE 7 table 4.3-1: Residential Floor LL = 40 psf Residential Balcony LL = 40 psf * 1.5 = 60 psf Two...

    Floor load error in STAAD Pro Connect

    Cool. Yes, in the past, we used to import a model drawn in CAD into STAAD. if the joints were not 100% connected, the model would have a disconnection errors. Obviously, you did not have that issue.

    Floor load error in STAAD Pro Connect

    Good to see that you are reviewing the programs output for sanity checks. I am curious if you were able to resolve this issue? A couple of questions come to mind: Did you use area load command? Are all joints connected? I am old STAAD user, never used the connect version, and I prefer to use...

    Effective Wind Area - Stud Wall with Parapet

    ASCE clearly defines the "span" from support to support. For further reading consult Guide to the Wind Load Provisions of ASCE 7-10 by Kishor C. Mehta, Ph.D., P.E. and William L. Coulbourne, P.E.. See Answer to frequently asked questions number 18 (quoted below): "18. Metal decking consisting...

    Combined Timber and Microlam Beam Load Sharing

    You are correct. The plan to consider loading the LVL for the live and wind loads only. It s to risky, I think, to jack the beam and alleviate the dead load.

    Combined Timber and Microlam Beam Load Sharing

    It has been a long while since I have been in this forum. Hello everyone. I want to pick everyone’s brain here. I have been called, of course after the fact, to evaluate a situation where a contractor has already installed a beam, 9.33’ span made up from SYP number 2. The beam is supporting 5...

    contractor not following plans... at all

    If what you are saying is 100% correct, then run Forest, run away from this job, as fast as you can.

    Digitally sign Structural drawing

    My current certificate will expire in few months and they are raising their fees. For cost comparison, before I renew, would you tell me which one they pointed you to? Their website and selections do not have FL board of engineers.

    Fall Protection on Platform

    OSHA and now ASCE 7 part 4.6.5 has provisions as the fall protection forces. ASCE 7 requires 3100 pounds live load. Keep in mind, if I recall correctly, when designing for these forces, you can use the ultimate strength.

    Digitally sign Structural drawing

    That is right. Florida has strict procedures, as it should be.

    Digitally sign Structural drawing

    Are you serious? What state is that?

    Digitally sign Structural drawing

    Florida has strict procedures for digital signing and sealing. We cannot rely on simply using digital signature in Acrobat or Bluebeam. Hopefully the following link will help you: https://fbpe.org/legal/signing-and-sealing-engineering-documents/ Lutfi

    Gross vs net uplift C & C Pressure

    I am curious as what fellow engineers here consider, to arrive at net C & C uplift pressure, as dead load resisting the gross C &C uplift pressure on roofs? Regards, Lutfi

    Surcharge for a Sea Wall

    It is settled. A surcharge of 100 psf is what my engineering judgement is telling me. This is based on the project and what I know what will happen. Thanks for those who chimed in. Regards, Lutfi Regards, Lutfi

    Surcharge for a Sea Wall

    TLHS, the site cannot be accessed by traffic due to existing trees, playground and fencing on two sides. The other tow sides are water/river. Lawn mower is the most that I can envision. I will use 100 psf. I was looking for a solid reference with surcharge values other than computing based on...

    Surcharge for a Sea Wall

    All, I am analyzing a sea wall that is used for a small park. The wall is retaining 4 to 6 feet of earth with the water in the river side is about 3 feet above the mudline. The wall does not appear to be subject to vehicular traffic. I am of the opinion that 40 psf surcharge would suffice. This...

    Crane Runway Beam Reinforcement

    Back in the day when I designed overhead cranes and runways, the channel was assumed to take the full lateral load. I wonder why the owner want the UC to be 0.85? Your approach seems to be viable. However, keep in mind that the DL from stiffening the runway add more more stress. bones206, I am...
