    Short Column Deflection

    Thank you.

    Short Column Deflection

    Ok. Jae. But I'm talking of isolated column with slenderness ratio about 8 only which is considered a short column. A column is considered a Slender Column when it's slender factor becomes 15 (length of column divided by column depth). So for our discussion. Let's consider a short column only...

    Short Column Deflection

    In short column, you often see the illustration in the file enclosed where (a) is a loaded column subject to eccentric compression (b) is the strain distribution at section a-a; (c) is the stresses and forces at nominal strength The formula in short column for the compression block in the...

    Short Column Deflection

    MJB315, I'm not yet designing. Just a fresh grad and reviewing my lessons. If you will review any book on short column and that includes any books for engineering students. It is emphasized short column is only based on material strength. Then you will be taught about the interaction diagram and...

    Short Column Deflection

    In a typical beam, the maximum moment occurs at midspan, and it is where the first tensional crack occurs. In a typical column, the maximum moment occurs at mid height, and it is where the first compression failure occurs (reaching strain 0.003). Can how can moment be maximum at the bottom of...

    Short Column Deflection

    It is column of exterior wall with eccentric loading and falls under short column (not slender column). But in the computations of interaction diagrams and especially compression blocks, they assume it occurs in all parts of the short column (from top to bottom with same value). But I think it...

    Short Column Deflection

    More specifically. Is the eccentric loading interaction diagram for a short column at mid-height only or throughout the span? I'm assuming the compressive strains at mid-height is greatest and getting smaller at top and bottom. Do you hold this position too?

    Short Column Deflection

    A short column is said to depend on material strength only. But you know deflection still occurs. It may be negligible, but I'm computing the corresponding strain of concrete at mid-height with respect to the upper and lower region. If concrete fails at a strain of 0.003 at mid-height. What...

    Aluminum Canopy

    My question was, how stable are these if they would be connected to a concrete beam by drilling holes at the sides and putting bolts into it? If it is steel beam, it is relatively easy as you can just use welding.

    Aluminum Canopy

    Client wants me to design an aluminum canopy that extends 35 inches outward from the sides of a flat boring looking house with solid canopy surface above and below (meaning no truss support can be seen outside it). My initial option is to screw angle bar to the concrete beam and extend it with...
