    Steel plate frame

    hi i would like to ask if a 10m cantilever frame made up of top and bottom circular steel sections infilled with steel plate, would the bottom compression circular chord be subjected to lateral torsional buckling ? if there is, how to braced them ? Another question is if a 50m roof truss...

    Steel Reinforcement Test To BS4449

    Hi Normally in the steel reinforcement test, we check for yield stress, ultimate tensile stress and elongation. i have come across a case where the rebar had achieved the yield stress and ultimate tensile stress but with very low elongation ? what is the reason ? another question is what is...

    Transverse Stability of long span truss

    Hi There is a curved steel truss of 50m span with two steel columns on each side. Transversely, this truss is spaced at 8m for 120m long. May i know how do i check the lateral stability of this long span truss in 120m direction although there are purlins on top of truss and cross bracing at...

    Wide rc beam on small column

    Thanks for the tips, Daveatkins. Refer to the same topic, how long is the short portion of beam bending in the 2.4 meter direction over the top of column need to be used for checking. Would the wide beam subject to torsion when one side of one way slab is loaded with live load ?

    Wide rc beam on small column

    Hi Recently i design a wide rc beam 2.4m x 0.6m with supporting one way rc slab. Should i use the normal design method of RC beam with ratio of width /height <1.0 to design wide beam ? how does the load at the overhang of beam near the small column transfer to the column if we use normal...
