LOADINGS [Hospital Block] 15

19. EARTHQUAKE LOAD Seismic Loads considered on the structure are as per IS 1893 (Part 1) – 2002 . As per the seismic map of India, Coimbatore lies in zone II Zone factor (Z) for zone II - 0.10 Importance factor (I) - 1.5 [For Hospital] Response reduction factor (R) - 5.00 [For SMRF] Percentage of Imposed Load considered in Seismic weight calculation - 25 % for LL < 3.0 kN/sqm 50 % for LL > 3.0 kN/sqm 16

20. As per Table 18 of IS456:2000, the load combinations for Limit state of Serviceability are 1.0 (DL + LL) 1.0 (DL +/- EL) 1.0DL + 0.8LL +/- 0.8EL As per Table 18 of IS456:2000, the load combinations for Limit state of Collapse are 1.5 (DL + LL) 1.2 (DL + LL +/- EL) 1.5 (DL +/- EL) 0.9DL +/- 1.5EL 17

21. 5 . SOIL INVESTIGATION DETAILS 18 Soil Investigation Report - Geomatrix Consultancy Foundation Type - Isolated Footings / Raft Depth of Foundation - 7.30m from LNGL Safe Bearing Capacity - 300 kN/sq.m. P.C.C (1:4:8) bed below foundation - 150mm The support reaction from ETABS is used for manual calculation of Isolated Footings.

22. As per IS 1893(part1):2002, for regular buildings less than 90m in height in seismic zone II, Linear Static analysis is performed using ETABS software and the design is also performed using the same. 6 . BUILDING ANALYSIS 19

26. The columns are designed directly using ETABS 2016 version 16.2.1 for the worst load combination and detailed as per SP: 34-1987 and IS:456-2000 Beam sizes vary according to the span and are designed using ETABS 2016 version 16.2.1 software for the worst load combination and detailed as per SP: 34 or IS 13920 as the case may be . Ductile Detailing has been done for columns of hospital block to resist Seismic forces and satisfies the codal requirements SUPER STRUCTURE 23
