Or An SDOF system is subjected to free vibration with an initial velocity Vo without any initial displacement. Determine the subsequent motion of the system for the three damping ratios. 2.5, 1.0, 0.1.
12. State and prove the orthogonality and normality property of mode shapes. Or A cantilever bar is to be modeled by a mass less uniform bar to which are attached with two lumped masses representing the mass of original system as k 2AE/L and m ρAL. Determine the natural frequencies and the normal modes of this model.
13. Explain briefly about the characteristics of strong ground motions. Or Write detailed notes on plate tectonic theory.
14. Briefly explain about the behavior of RCC and Steel building under earthquake loading. Or Discuss in detail about the lessons learnt from the past earthquakes.
15. A RCC beam of rectangular section has to carry a distributed live load of 20 kN/m in addition to its own weight and a dead load of 25 kN/m. The maximum bending moment and shear force due to the earthquake are 60 kN-m and 40 KN respectively. Center to center distance between supports is 6 m. Design the beam using M-20 grade and Fe 415 steel. Or
Write the importance of ductility in earthquake resistant design of RC buildings. And also explain the ductile detailing considerations in column members as per IS 13920:1993.
