    Shear Transfer at Column Base Plates

    Yes, grouting the oversized holes is a necessity purely from a protection against corrosion aspect point of view. No grout - bolts exposed to groundwater. Low shears can be transmitted through the bolts, but in cases of high shear, consider as noted above, welding a stub section to the...

    Curvature on straight steel beam

    I would argue in the UK that what comes out of the mill has to confirm to standards and their own quality assurance proceedure and should conform to BS EN docs. Its certainly not down to the fabricator to bend it back to "straight" in the sense of the code, as this could have further...

    File/Application opening problem

    Hi, I'm a first time poster from the structural Eng. section, and was hoping someone could possibly help me. Whenever I try to open a jpeg file, my pc always opens acrobat, and then fails miserably! I need to correct the "opens with" program, but don't know where to begin, I assume I should be...

    Flange Bracing Design

    In th Uk we use 2% of the squash load of the compression column flange. Forced required in Brace = 0.02BTpy. B= Flange width T= Flange thickness py= Steel strength.

    PDX

    Hello, I've recently been looking into a company which produces a steam pumping device which is said to be able to emulsify products at high flow rates. Has anyone come across it, and does anyone have any thoughts if it is viable? The link to their website is http://www.pursuitdynamics.com Many...

    Calculation of Stiffness constant

    Hi John0D1, Yeah you are correct, each individual element does have its own stiffness coeeficient when related to others. Normally, for simple sub frames k (individual stiffness) can be related to I(second moment area) divied by L, length of element. For a continous member, I/L is multipied...

    shear modulus for wood? inexistent?

    The shear modulus G in timber design in the UK (to BS:5268) is taken to be E/16. The central deflection due to shear on a beam from a UDL is calcualted using wL*2/(8AG) then multiplying by a form factor, C (1.2 for a rectangular section) this is then added to the deflection due to bending.
