An unstiffened web $${\rm I}$$ section is fabricated from a $$10$$ $$mm$$ thick plate by fillet welding as shown in the figure. If yield stress of steel is $$250$$ $$MPa,$$ the maximum shear load that section can take is

When designing steel structures, one must ensure that local buckling in webs does not take place. This check may not be very critical when using rolled steel sections because

An $$ISMB$$ $$500$$ is used as a beam in a multi-storey construction. From the view point of structural design, it can be considered to be 'laterally restrained' when,

The problem of lateral buckling can arise only in those steel beams which have
