Precast concrete can beat the seismic challenge


Precast concrete can beat the seismic challenge

Precast concrete elements are a great solution, when designing a building to a high seismic zone. India is known to be a country dealing with high seismicity, which has a major impact on the construction sector. However, seismicity wasn’t a problem, when Nestlé decided to build its Research and Development Centre to Manesar, which has very high seismic conditions (zone four).

Nestlé R&D Centre is a unique precast structure, the first of its kind in India. Prakash Shah, Head of Technical Support at Elematic India, says that the constructor sector in India is unfamiliar with the seismic performance of precast concrete technology; however it has taken a major step forward as part of a building design in seismic areas. Hence, Nestlé R&D Centre leads the way for impressive precast construction in seismic zones.

Elematic India Pvt Ltd developed the concept design for the Centre. The design objectives were to create large open areas for maximum flexibility, have high loading capacity (up to 15kN/m², which is 7.5 times residential loading) and ability to withstand earthquakes. The region has peak ground acceleration (PGA) of 2.4m/s² and soft soil conditions, meaning that the building had to fulfil the national building code governing earthquakes, IS-1893.

Pre-stressed concrete was the most suitable option, because of the high demands of the structural system. The rapid construction speed also supported the decision to use precast elements for the Centre. Elematic supplied machinery / precast plant to be operated by a local contractor Survi Projects Ltd. According to Prakash Shah ‘’the main process area had long slab spans of 12.0m, because of the high occupancy loads. Further due to the hygiene requirements, a composite building system of pre-stressed precast solid slabs with structural topping over entire area was used for the project, acting as diaphragm. Lateral load (seismic and wind forces) resisting system was formed using cast-in-situ shear walls.’’

The finalized building meets the required structural design, rigidity and serviceability criteria. Not to forget about the visual aspects, the building is beautiful with its concrete walls. Hence, you can create long-lasting structures suitable for high seismic zones, yet make them look appealing.
