Detailed design of the exposed steel structure

  • Comment

Studies were made to establish the size of a secondary beam capable of spanning 9m unrestrained, but with a top flange narrow enough to allow the precast coffer units to be lowered onto the bottom flange.

As it would be exposed, a slender bottom flange was considered desirable.A simple 457 x 191mm universal beam offered the advantages of minimal fabrication and a slender bottom flange.The shape of the coffers was designed to fit this section within defined tolerances.

It was considered safer to install the coffers by keeping them horizontal when lowering them, but the top flange interfered with this process.This problem was solved by lowering each coffer (above) at 45degrees to the beam until it slotted between the flanges, and then rotating it onto the bottom flange.The top flanges were cut back at the perimeter, to allow the last two coffers to be lowered without rotation.
