GATE (CE) : Engineering Mechanics & Design of Steel Structures #7 (App update required to attempt this test)

In Double-laced column construction, the thickness of the flat lacing bars shall not be less than:

Assuming that there is no possibility of shear buckling in the web, the maximum reduction permitted by IS 800-2007 in the (low-shear) design bending strength of a semi-compact steel section due to high shear is

A steel rod of 20 mm diameter has been used as a tie in a bracing system. The tie may be subjected to possible reversal of stress due to wind. What is the maximum permitted length member as per IS: 800 – 2007?

ISMB 100 (r_x = 40mm, r_y = 8mm) has been used as a column in an industrial shed. Along the minor axis, the column has restraints in the form of purlins at 2.0m intervals. Effective length factor along major and minor axes are 1.3 and 1.1 respectively. If the slenderness ratio is restricted to 100, the maximum column height will be

A compound column had been fabricated with 4 angles of ISA 60 × 60 × 6 placed at corners of a square 400 mm × 400 mm. The radius gyration of single angle is 11 mm. For the fabricated built up column, the overall slenderness ratio is 50. What is the maximum distance (in mm) between lacing bar attachments at the fabricated columns?

A compound column has been fabricated with 4 angles of ISA 60 x 60 x 8 mm placed at corners of a square. The radius of gyration of angle is 12 mm. The overall slenderness ratio, for the column, is 40. What is the maximum distance (in mm) between lacing bar attached at the fabricated column?
