Stellar 1422 case study
Project details
Stellar 1422 is a landmark commercial development in Noida, designed to stand out among the city’s premium business spaces. The project comprises a total built-up area of 453,778 sq ft with a typical superstructure floor plate of approximately 31,861 sq ft. The building includes a single basement and rises 11 storeys above ground. It is located in Seismic Zone IV and has been designed in accordance with IS 1893. To achieve higher speed, accuracy, and quality of construction, the project adopted a precast modular construction approach.
Design Board
The initial framing plan was developed based on the architectural layout. Precast structures in high seismic zones are generally avoided in India due to performance concerns, and the early scheme reflected this hesitation with an excessive number of shear walls that conflicted with the architectural vision.
To resolve this, the team evaluated alternative lateral force-resisting systems including base isolators, viscous dampers, friction brakes, and fluid devices. After a comparative study, Seismic Brakes supplied by Imperial were selected. They allowed clean integration with the architecture, reduced the dependency on heavy shear walls, and enabled a more efficient and dependable LFRS with optimized connection detailing.
The revised framing plan incorporated Yield Restrained Braces equipped with Seismic Brakes. The enhanced structural system was validated through a full non-linear time-history analysis. Comparative snapshots of the original model versus the damper-integrated model demonstrate the improved behavior under seismic loading. Imperial’s design team worked closely with us throughout this process and their technical involvement added significant value.
IMPERIAL Benefits
The use of Seismic Brakes in Stellar 1422 resulted in several measurable advantages
Reduced structural cost compared to the conventional shear-wall-based scheme
Lower consumption of concrete, steel, and shuttering materials, contributing to green building credits
Faster construction cycle due to precast methodology and reduced wall density
A more reliable and resilient structural design capable of superior seismic performance
