MITEK LIGHT STEEL FRAME BUILDING
GLA School Hall, joint winner in the MiTek Light Steel Frame Building
Category
he smart design using MiTek's Ultraspan aided
in capturing benefits made possible by high
strength low mass steel trusses, realising the
architect's design. From natural ventilation to
optimisation of natural light, photo voltaic cells
and rainwater harvesting, to the recyclability of materials
used - LSF made this green structure possible!
All trusses for the GLA school hall roof were spanned
parallel to the traditional supports, essentially producing
enlarged rafter/purlin type trusses. Ultra-Span girders
were created at the ends to support short span trusses to
comply with the required minimum ceiling height.
This idea was also adopted in the middle section of the
roof to act as stability braces for the window panels.
Window panels were made with MiTek's wall framing
product to allow for very specific window sizes, and to
provide flat surfaces for fixing of such windows. These
window panels are manufactured in several parts to ease
installation.
In typical large span Ultra-Span style, the 19m trusses
were preassembled in braced pairs and then lifted into
their final position on the roof. This ensured fast erection
of the roof structure skeleton and enabling other
installation works to continue on a stable platform.
