    Recommended Anchor Bolt Torques

    Is there a table or a publication of recommended anchor bolt torques for cast-in-place anchors? Hilti provides maximum anchor bolt torques base on the bonding of their epoxies. For cast-in-place anchors, I imagine that it could very based on allowable concrete strength and rather a nut or a 3"...

    Curved beam

    Here are all the references that I have on curve beam design, all out of past AISC Engineering Journals. Horizontally Curves Steel Girders-Fabricated & Designed by W.M. Thatcher, July 1967. Analysis of Curved Girder Bridges by Charles Culver, Darryl Brogan & David Bednar, January...

    Continuously Welded Railroad Track

    Dear ishvaaag, I believe that I understand your reply but I just want to clarify thru the following: Are you saying that all expansion stresses are being accommodated by the rail material itself? In other words, is the rail possibly seeing a very very slight non-axial deformation due to the...

    Aluminum Bolts used in a "slip-critical" case (cyclic loading & fa

    A solution that I have been promoting is to use 1/2" Dia. A325-SC (slip critical) bolts turned down (or necked down on a lathe at the shear plane) to 1/4" dia. The minimum diameter of A-325 high strength bolts is 1/2". Torque the bolts to 35 foot pound. Each bolt should should...

    Aluminum Bolts used in a "slip-critical" case (cyclic loading & fa

    I have a situtation where a 1" steel plate is bolted to a 5/8" aluminum plate with 1/2" diameter 6061-T6 aluminum bolts with a 27 foot-pound torque (let's ignore the galvanic action for now). The plates are not allow to slip. 262 Locktite Threadlocker has been applied to the...
