    residual stresses due to welding

    I'm looking for a residual stress value to use for the analysis of an existing structure - a beam-column (Fy=33ksi) with plates (A36) welded to each flange. (The member was rolled, then, after 40 years of service, these flange plates were added by continuous fillet welds on each edge of the...

    P-delta experts?

    I'm working on an interesting steel frame problem that doesn't completely follow standard guidance, but I'm basically following AISC, using 2nd order analysis by amplified 1st order analysis. Rather than using AISC's guidance to determine and use B2 to estimate total Mlt, can I sub (B2*Mlt)...

    k - subgrade reaction

    Hopefully this is an easy one. I haven't seen this written anywhere, making me doubtful, but it seems that there be a strong correlation between k and f'c, if the subgrade is concrete. (in my case, the "foundation" is the plain concrete within a dam) In fact, it seems like I should use f'c...

    Shear-Friction Design Method for Reinforced Concrete

    I have ACI 318-02 (11.7.4) and a reinforced concrete textbook. Here is my understanding of the shear-friction design method: This method of determining Vn considers shear capacity of "dowels" as well as the friction between adjacent faces of a plane of concrete, whether the plane is the result...
