PARAMETERS FOR STRUCTURAL STABILITY - HM SWEARS BY
The structural system for the HM apartments comprises of conventional RCC Beam and Column construction. Every measure is taken to ensure the best standards are strictly maintained for stability of the building within the purview of the Indian Standards
HM ensures that the geometrical dimensions, member properties and member-node connectivity, including eccentricities are modelled in the analysis problem. The computer analysis produces individual member forces, reactions at foundation level and deflection pattern of the entire structure as well as individual members. HM uses this data to confirm / review the member sizes and arrive at the most appropriate design of the structural members for arriving at the optimum structural space frame characteristics that satisfy the strength and stability criteria in all respects.
All R.C.C structures of HM projects are designed according to the Limit State Method as specified in IS: 456 – 2000.
With consideration for strength and durability, minimum grade of concrete used is M20. Grade of concrete for column used is M40 at lower levels and varied to M30, M25 & M20 at higher levels.
High Yield Strength Deformed bars conforming to IS: 1786 with Fy = 500 Mpa is used as reinforcement.
Columns are spaced at required locations as per Architectural drawings and designed to effectively resist the gravity loads & lateral forces due to earthquake and wind.
The lift cores are with RCC walls highly contributing to the lateral stiffness of structure.
Steel reinforcement is of Grade Fe500 conforming to IS: 1786-1985.
The superimposed load or otherwise live load is assessed based on the occupancy classifications as per IS: 875 (Part 2) 1987
The wind pressure is calculated based on the provision as laid in IS: 875 (Part 3) – 1987.
The loading due to earthquake is assessed based on the provisions of IS: 1893–2002. As per this code, Bangalore lies in Zone II.
