Questions
Module I
- Q1. Explain briefly about various Rolled steel sections used in Indian standard code for steel structure. [25 marks]
- Q2. Design a bolted bracket connection to transfer an end reaction of $300\text{ kN}$ with an eccentricity of $170\text{ mm}$, due to factored load. The steel used is of grade FE 410. Use $20\text{ mm}$ diameter bolt of grade 4.6. The thickness of bracket plate is $10\text{ mm}$ and the column section is ISHB 200 @ $365.91\text{ N/m}$ [25 marks]
Module II
- Q3. Design a bridge truss diagonal subjected to a factored tensile load of $300\text{ KN}$. The length of the diagonal is $3.0\text{ m}$. Design a suitable section for the tension member. The member is connected to a gusset plate $16\text{ mm}$ thick with one line of $20\text{ mm}$ diameter bolts of grade 8.8 Use Fe 410 grade of steel. [25 marks]
- Q4. Design a built up column with four angles. The column is $12\text{ m}$ long and supports a factored axial compressive load of $700\text{ KN}$. The ends of the column are held in position and restrained against rotation. Design a suitable connecting system. Use steel of grade Fe 410 [25 marks]
Module III
- Q5. Design a laterally supported beam of effective span $5\text{ m}$ for the following data Grade of steel Fe 410. Factored maximum B.M. $= 180\text{ KNm}$. Factored Shear Force $= 220\text{ KN}$ [25 marks]
- Q6. Design a welded plate girder $24\text{ m}$ in span and laterally restrained throughout. It has to support a uniform load of $100\text{ KN/m}$ throughout the span exclusive of self-weight. Design the girder without intermediate transverse stiffeners. The steel for the flange and web plates is of grade Fe 410. Design the cross section the end load bearing stiffener and connections. [25 marks]
Module IV
- Q7. Design a built-up column $10\text{ m}$ long to carry factored axial load of $1080\text{ KN}$. The column is restrained in position but not in direction at both ends. Provide single lacing system with bolted connections. Assume steel grade Fe 410 bolts of grade 4.6 i) Design the column with two channels placed back to back ii) Design the column with two channels placed toe to toe Which of the two system is economical. [25 marks]
- Q8. A column section ISHB 350 @ $710.2\text{ N/m}$ carries a factored axial compressive load of $1700\text{ KN}$ and factored bending moment of $85\text{ KNm}$. Design the base plate and its connections. Assume concrete pedestal of M 20 grade. use Fe 410 grade of steel. [25 marks]
