UNIT-I

1. a) Explain the term Radius of Gyration and effective length of columns. 5
   b) Design a single angle connected to a gusset-plate (with two bolts) to carry 180 kN factored load. The length of the strut is 3 meters c/c. Assume f_y = 90 MPa. 7
2. Determine the design axial load carrying capacity of the column of ISHB 300 @577 N/m if the column is 3.0 m long with both ends-pinned. Take f_y =250 MPa. 12

UNIT-II

1. a) Discuss classification of cross-sections on the basis of IS 800:2007. 5
   b) Discuss bending and shear strength of a laterally supported beams. 7
2. An RCC slab is supported on steel beams of effective span 8.3 m which are spaced at 3.0 m c/c, Allow a live load of 3.0 kN/m². Take dead load as 12.8 kN/m’. Design an I-section (beam) and check it for deflection also. 12

UNIT-III

1. Design a tie member of truss for pulling force of 250 kN check it for reversal of stresses under wind loads, compressive force to be included in the member is 60 kN and node to node distance is 2.0 m. 12

2. Design a strut for a compressive force of 50 KN and tensile form of 70 kN (under reversal of stresses). The length of the strut is 2.235 m. 12

UNIT-1V

1. Design suitable beam sections for upper tier of a two-tier grillage foundation for a column to support an axial load of 2000 kN. The size of the base plate is 800 x 800mm.The safe bearing capacity of soil is 200 kN/m². 12
2. Draw a neat sketch of two-tier grillage footing along with its bending moment diagram. Mark the point of maximum bending moment and shear force. Also explain under what circumstances the grillage footing is provided. 12

UNIT-V
