   2. Design special slender shear wall for the hospital building of span length 30m.
4. What is Base shear force? Discuss briefly the various factors on which it depends. Illustrate using proper equations as per IS 1893.
5. Special care is taken while providing openings in bearing walls. Justify it as per IS 4326.

SECTION-C

1. A block of mass 80 kg is suspended from a spring having stiffness of 820N/mm. An unbalanced disturbing force of 450N is acting on it, with frequency equal to .65 times the natural undamped frequency. Calculate natural frequency of undamped and damped vibrations. Also determine the amplitude of motion due to unbalance and the phase difference with respect to exciting force.
2. Appropriate measures should be considered while providing splices in RC components. What are those provisions in case of Beams and columns as per Indian Standard Code of Practice for Ductile Design and detailing of Reinforced Concrete Structures, subjected to Seismic Forces?
3. Discuss any two past Earthquake studies in detail. Also enlist various lessons learnt from those Earthquakes.
