Redevelopment of Rani Kamalapati Station Bhopal India
India‘s first world class Railway Station Building, redeveloped under the Public Private Partnership (PPP) model.
The redevelopment of former Habibganj railway station started in 2019 and was completed in 2021. A new steel structure building was designed with a foot over bridge connecting six tracks and five platforms.
The building was renovated to LEED „green building“ standards with energy-efficient equipment, solar energy and wastewater treatment for reuse.
Challenge
In order to keep the stay in the station concourse as comfortable as possible, vibrations from rail traffic had to be isolated as far as possible. The station concourse is made of steel and it was necessary to equip the structure with a vibration isolation system to comply with the 72 VdB limit in the station concourse.
The base plate construction of the hall required an integration of the solution to ensure complete stability under wind and earthquake loads without significant changes to the structure.
Solution
In collaboration with the structural engineers and acoustic consultants, GERB developed a solution to the vibration problem. The acoustic consultants recommended a 12 to 16 Hz building isolation at the base of the terminal building as a result of a detailed predictive analysis of the vibrations using the FEM of the proposed terminal building. The consultants also carried out a detailed measurement of the source spectra. The loading input data was provided by the structural engineers, which enabled GERB experts to find the best fitting elastic support solution meeting the projects individual requirements. GERB carried out a detailed NOVODAMP® closed-cell polyurethane sizing calculation with different sizes of pad type B1200.
Technical Facts:
Structure: Steel concourse and foot over bridge
Vibration source: Train Traffic
Base isolation frequency: 12.8 to 14.6 Hz
Design load: 74,900 kN
Result
With different sizes of the NOVODAMP® B1200 bearing pads, the required range of frequency of 12 to 16 Hz was achieved. Type B1200 comes as standard in a height of 25, 37.5, 50 or 75 mm, whereby the size can be flexibly cut to size. Completing Rani Kamalapati Station project, GERB provided most optimum turn-key solution starting from design and selection of NOVODAMP® pads, design calculations, supply, installation and test measurements.
