    Repair Welding Under Load

    There is a article titled "Repair Welding Under Load" that was published in 1990. The authors are Huenersen, G. / Haensch, H. / Augustyn, J. This article was published within the "Welding in the World" Volume 28, Issue #9 and issue #10 journal. I have contacted the publisher, of "Welding in the...

    ANSI A58.1-1955 - Minimum Design Live Loads

    Thanks for all the helpful links and info. Does anyone know if this document was released before the 1945 version?

    ANSI A58.1-1955 - Minimum Design Live Loads

    Does anyone know where I can find a copy of ANSI A58.1 - 1955? I already have the 1972 and the 1982 version of this standard. I am looking for a copy of the 1955 version and NO one seems to be selling a copy. Any information would be well appreciated.

    Lateral Bracing of Steel Beams - Lateral-Torsional Buckling From Simple Bending

    In typical structural steel construction, shear connections are commonly used on the ends of beams. These shear connections are typically double (clip) angles welded to a beam and bolted to another beam. The distance to the first bolt, from the top of the beam, is usually 3" and additional bolts...

    Masonry Crawl Space Wall - Seismic Class "D"

    I have a 4'-0" deep Masonry Crawl space wall, below grade, that is on top of a continuous footing. Throughout its entire length, the masonry wall supports the shear wall from the building above. We are in Seismic Class "D", so the building shear walls do impose the seismic shear load into the...

    ASCE7-10 - Table 12.2.-1 - Issue

    Table 12-2-1 Page 60 of the ASCE7-10 Standard, under "Building Frame Systems". Looking at "Steel Ordinary Concentrically Braced Frames", Seismic Design Category "D". It lists "35" with an "j". Footnote "j" explains that these frames can be used up to a height of 60 ft where the dead load of...

    Allowable Capacity of C1020 Cold-Rolled Steel

    It is being used within a residential building, so a pedestrian walkway would be the same. Are there any references available?

    Allowable Capacity of C1020 Cold-Rolled Steel

    Can someone tell me what allowable capacities are used when determining the allowable capacity of C1020 Cold-Rolled Steel? I know what the tensile strength and the ultimate strength mechanical property values are, but, is there a code book or some other reference that describes the safety...

    ACI 14-1

    I am looking at a document that shows a formula for calculating the compressive strength of a foundation. This document says "Compressive Strength per ACI 14-1" and the formula they use is: P=452(.25(3000)-24(.0066)] = 339 Kips This is clearly not from ACI318 because chapter 14 is for walls...

    Bolt On Reinforcing - Built-Up Steel Members

    I'm looking for actual documentation that shows this. Hopefully there is supporting lab tests that have been done. Anyone know if such test and documentation exist? Thanks.

    Bolt On Reinforcing - Built-Up Steel Members

    Does anyone know if extensive load testing as been done on steel members that have been reinforced by bolting on reinforcing? I am looking for actual testing reports & documentation that shows bolting on reinforcing works or doesn't work. Bolting on steel to existing steel members to build up...

    Spring Release Relief Mechanism

    MintJulep, That may work, but, getting the nut returned back to the original postion is an issue. I cannot place a spring on the opposite side. I am thinking of a retainer of some sort that would expand when voltage is applied to it. I don't know, maybe some more people here have ideas?

    Spring Release Relief Mechanism

    The pwer is available to activate the solinoid. There isn't enough to overcome the spring There is power to activate the solinoid if there is little or no retuirn spring force. Something needs to be done with the retainer. Any ideas?

    Spring Release Relief Mechanism

    It can't be a latch solinoid because this would require the solinoid to have to overcome a force (spring). The goal here is that when the solinoid is activated, there would be little to no force the solinoid would have to overcome. The spring compression (or force) would be activated only if the...

    Spring Release Relief Mechanism

    I have a simple electric linear pull solinoid. The solinoid has a linear return spring on the plunger. The plunger has a "C" washer that is used as a spring stop so that the spring will compressed wheen the solinoid pulls it's distance. I would like to replace the "C" washer with something that...
