TKN/KS/16/2249 1 B.E. (Civil Engineering) Seventh Semester Advanced Concrete Structures P. Pages : 4 TKN/KS/16/2249 Time : Four Hours Max. Marks : 80 _____________________________________________________________________ Notes : 1. Answer three questions from section A and two questions from section B. 2. Due credit will be given to neatness and adequate dimensions. 3. Assume suitable data wherever necessary. 4. I. S. 456 (Revised) I. S. 875 may be consulted. 5. Use of non-programmable calculator is permitted. 1. Find the moment of Resistance of T- Beam if the beam also carries a compression reinforcement in the form of 4 x 20 mmprovided at a distance of 40mm from the top fibre as shown in fig (1). Use M20 concrete and Fe415 steel. 100mm 600mm 300 5x204x20mmb f =750mm Fig.1 13 2. Design a biaxially eccentrically loaded braced rectangular column to carry an ultimate axial land of 1500 kN and ultimate by axial moments of Mux = 150 kN.m and Muy = 100 kN-m. acting about axes bisecting the depth and width of column respectively. The effective length about x-axis is 3m and about y-axis is 2.75m. The unsupported length about both axes is 3.5m. Column size is B= 400mm D= 600mm. Use M25 concrete and Fe415 steel. 13 3. Design isolated footing for a rectangular column 600mm x 400mm. Carrying an axial load of 800 kN and a bending moment of 125 kN-m the safe bearing capacity of soil is 150 kN/m 2 . Use M20 grade of concrete and Fe500 grade of steel. Draw the reinforcement details. 13 4. Determine the reinforcement required for a rectangular beam section with the following data. i) Width of section = 300 mm ii) Factored B.M.= 90 kN-m. iii) Depth of section = 600 mm. iv) Factored torsional moment = 50 kN-m. v) Factored shear force = 80 kN. Use M20 grade concrete and Fe415 grade of steel. 13 *0869* NagpurStudents.Org
