If the cost of purlins/unit area is p and the cost of roof covering/unit area is r, then cost of trusses/unit area for an economical spacing of the roof trusses will be

A welded plate girder of span 25 m is laterally restrained throughout its length. It has to carry- a load of 80 kN/m over the whole span besides its weight. If K = 200 and f_y = 250 MPa, the thickness of web will be nearly

Consider the following with regards to intermittent fillet welds.

I. The minimum effective length should be 40 mm or 4S whichever is more

II. The maximum clear spacing between weld pieces shall be 12t or 200 mm whichever is minimum in case of compressing members

A 100 kN electrically operated crane (EOT) is provided on the gantry girder of an effective span of 8 m in an industrial buildings.  Now, another crane of capacity 50 kN hand-operated is provided on the same gantry girder used in some other industrial building. What would be the effective length (in m, up to three decimal places) of this gantry girder (on which 50 KN crane is provided) such that maximum vertical deflection allowed in gantry girder as per the codal provisions of IS 800:2007 remains same in both cases?
