Project 1_Comparative study of different storey buildings for Seismic forces
GIVEN :
To compare the Factors influencing the dynamic charateristics, natural period and modes of shape of the given buildings: A, B, C, D, E, F, G, H, I, J, K
1. Illustrations for building A : start with the input
2. Add grid and stories-
3. View-
4. Define materials-
5. Define Beams, Columns and Slab-
6. Select pin connection as per given condition-
7. Add Loading-
8. Add live loads to slab-
9. Add frame loads to beams (brickwall)-
10. Define massource-
11. Define load combinations-
12. Add diaphragms to floors-
13. Define modal cases-
14. Check Model and Run analysis-
15. Run Analysis-
BUILDING A
Repeat the same process for the rest and display the time period results for the same-
BUILDING B
5 storey , Columns 400x400
BUILDING C
5 storey C 550X300
BUILDING D
5 storey C300X550
BUILDING E
10 storey, upper 5 storey - C400X400, lower C600X600
BUILDING F
10 storey , C600X600
BUILDING G
25 storey , upper 5 - C400X400, middle 10 - C600X600, lower 10- C800X800
BUILDING H
25 storey C800X800
BUILDING I
25 storey, Imposed load 10% - Live load 3.3 kN/m^2
BUILDING J
