Time: 3 Hours Max Marks: 70
Answer ONE Question from each Unit
All Questions Carry Equal Marks
All parts of the question must be answered in one place only
Note: Use of IS 1893:2002 (Part IS 1320 is Permitted
UNIT I
1. What is strong ground motion? State and discuss their characteristics.
How is the local magnitude of an earthquake related to the intensity of earthquake?
2. Determine the natural circular frequency and natural period of vibration of a system of weight
5x105 N. The lateral stiffness of the system is 3x105 N/m. What is the mass of the system?

What are the various types of dynamic loads? State some of the characteristics of dynamic loads.

UNIT II
3. Simplicity and symmetry are the key to making a building earthquake resistant. Explain the
concept with the help of neat sketches.
Explain in detail identification of seismic damage in RCC buildings.
4. Irregularities of mass, stiffness and strength are not desirable in buildings situated in earthquake
prone areas. Describe using diagrams how these occur and affect the building.
Write down the basic elements of earthquake resistant design
UNIT III
5. State the assumptions made in analysis of earthquake resistant design of buildings
Briefly explain the procedure of response spectrum method of analysis
6. Discuss the factors required for assessing
The lateral design forces ii) The design response spectrum
Briefly explain the procedure to calculate the seismic weight of buildings

UNIT IV
7. What are the principles of earthquake resistant design of RC buildings.
Define shear walls and how are the shear walls are classified.
8. Design a rectangular RCC beam of 7.5m span supported on RCC columns to carry a central
point load of 125kN in addition to its self weight. The moment due to seismic force is 40kN-m
and shear force is 50kN. Use M20 grade concrete and Fe 415 Steel. Sketch the reinforcement
details.
Define shear walls and how are the shear walls are classified.
UNIT V
9. Explain the design procedure of two storey masonry buildings with examples.
Define bands? At what levels in a masonry building would you provide them? Give justifications
for each of them?
10. Determine the lateral forces on a two-storey unreinforced masonry building situated near Allahabad
(Zone-II) for the following data. Plan size 18mx18m, Total height of the building
6.2m, Storey height 3.10m, Weight of roof 2.5kN/m2, Weight of wall 5kN/m2, Live load
on roof Live load on floor 3kN/m2, Zone factor Response reduction factor= Soil:
(Type-II) Medium soil.'
Briefly explain about the damages and non damages of masonry structures.
