Rabale Railway Station Pride of Navi Mumbai

Rabale Railway Station

Tekla Structures 3D BIM Technology made it possible to model and detail the complex structure of Rebail Railway Station at Navi Mumbai with accuracy and simplicity

Rabale railway station located in the planned city of Navi Mumbai, is an extension to the Mumbai Suburban Rail Network. This new project line was proposed to offer connectivity between Thane and Navi Mumbai. It covers an area of 18.5 kilometres between Thane and Vashi (Navi Mumbai). Rabale Station is a cutting edge unique master-piece of architectural design. The station does not ornate Victorian arches or cobble-stone pathways; its futuristic design, form, and use of materials are enough to turn heads and make one pause in wonder. Tekla Structures 3D BIM technology was used by Techflow Engineers to model and detail such complex structures.

Technical Features

Rabale Railway Station
Rabale Railway Station uses a combination of structural steel and acrylic sheets with specially designed joints between the materials to create the structure for the enclosure. The structure is made up of plate fabrication. The station uses daylight as the primarysource of lighting. The size and triangular-shape angles of skylight trusses play a vital role in the roof framing, which brings sunlight down to the central part of the platform throughout the day.

Trusses: Instead of putting trusses perpendicular to the tracks, they are running parallel to the platform. This made the architect to take long span trusses which avoid conjunction on platform for passengers. These trusses are running over three supports, which are 30 metres apart. The bottom of the truss is located 17 metres from the ground.

The triangular shape of the truss comprises bottom and top chord. The bottom chord of SHS 200x200x8 at 3.6 metres apart. The bottom chord is placed with face inclined. The top chord of the truss is a pipe with diameter 324x8 at height of 2.4 metres from the bottom chord. The diagonal members of SHS 100x100x6.3 run between both the chords.

This forms an irregular cutting edge. While detailing the part of each diagonal member, Techflow had to plot it on a graph sothat contractor can make a template from it. This could not be possible without Tekla Structures, says Techflow representative.

Columns: The unique 'X' shape columns add an aesthetic look to the structure, but this makes connections unconventional. These columns are made up of plate fabricated sections due to non availability of standard rolled section.

Canopy: Two plate fabricated canopies at entrance are made with the help of beams and girders. These are perpendicular to longitudinal trusses. Bottom chord of the canopy modeled with big plate girders in triangular shape. At junction HSS sections and plates connecting four rafters both top & bottom chords at canopy along the ridge.

Due to multiple members connected at one point in this structure, we typically detailed the connections as one assembly. This is possible only in Tekla Structures, says Techflow.
