    Damaged Shear Wall, or lack thereof

    Mjaret.... The square shape was what I expected you to say. Houses that are essentially square are more prone to rack in a wind, seismic, or settlement (as DonPhillips said) event....and the greater the height to the footprint ratio of the said structure makes an even greater possibility of...

    Damaged Shear Wall, or lack thereof

    Cracks radiating out from windows and openings at diagonals, in my mind, is indicative of some type of torsional event....it sounds like the entire structure tried to "rack". What CSD72 said on his No. 3 sounds like a very viable possibility. The relative stiffness of the external finish is...

    Metal Bldg Drift w/ Brick Veneer

    I would say that you can spec h/500, L/750, drift/1000....hide behind anything that you want....just remember that this linear term has exponential cost. Know what you have spec'd before just giving it a blank term off of another set of drawings. H/240 as I have said before is an extremely...

    Hourly Rates vs Fees vs Liability

    Dont be scared to ask for a sum...You are providing a service not just an hourly amount. I am under the impression that you probably will not starve to death if your customer says no.....so....dont be scared, your time/ideology/drawings/seal is worth an amount....tell them...I promise less than...

    Concrete Cover w/ vapor barrier

    I would opt on the side of error...vapor barriers are easily omitted. Keep the 3"...low cost, but could protect a large error

    Allowable Steel Stress in Foundation Hairpin

    It sounds like your engineering reasoning is 100% valid.....as UcfSE said, 50% might be a substantial understress, but it is also fairly cheap insurance as well. As I get more experience, the thing I feel is the most important to me is where I can place the redundancies without a large...

    Metal Bldg Drift w/ Brick Veneer

    I doubt seriously that you will find a code provision alluding to this that will suit what you are needing. Unfortunately, you are the one that probably has to make the determination. The Metal Building Code Manufacturers Association calls out a building drift of H/60 for buildings with non...

    Crazy Seismic Question

    I am a student of the NW Tennessee area....heck I am also a large landowner there as well....you are correct in saying this is the most seismically active area in the US. The area is overdue for an earthquake....the seismic coefficient (Sa) for the area that I own property (Dyersburg) is 2.2...

    NCEES Council Record

    I am registered in 11 states, and in some states it helped more than others. As long as I have the idea that I may get registered in another state, I will keep it current, as the fees are not that much. If you know for a fact that you are not getting registered in any more states, it is simply...

    Perf Bond and Payment/Material Bond for Design Professionals

    I have never heard of this and would definitely raise an eyebrow to this. As DRC1 said, it sounds like a spec writer may have been filling in for a sick colleague or something of the like. If this really is what the governmental agency is wanting, then you have to ask yourself if this is...
