SECTION-B
11) Discuss the role of confinement reinforcements in RC buildings. Explain briefly where it
is provided and what provisions of IS13920 are to be followed.
12) Differentiate between Magnitude and Intensity of Earthquake.
13) a) Discuss various lessons learnt, in case of traditional rural buildings, from past
Earthquake studies.
b) Design special slender shear wall for the hospital building of span length 30m.
14) What is Base shear force? Discuss briefly the various factors on which it depends.
Illustrate using proper equations as per IS 1893.
15) Special care is taken while providing openings in bearing walls. Justify it as per IS 4326.
SECTION-C
16) 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.
17) 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?
18) Discuss any two past Earthquake studies in detail. Also enlist various lessons learnt from
those Earthquakes.
