Roof Structural Program of Main Plant for GuanDi Hydropower Station

Abstract:

Concrete beam and slab system is commonly applied in the main plant roof of hydropower station, which is difficult for construction and slow, having a great impact on the construction period. For the main plant roof structure (span of 30 metres)of GuanDi hydropower station in Yalong River, this paper proposes three light steel roof systems, which are arched corrugated steel roof, light gauge-steel and shell roof, and carries detailed analyses and comparisons on the force calculation, appearance, the amount of steel, site construction, anticorrosive performance and other aspects. Regarded that the light gauge-steel roof is the most suitable system for the main plant roof of hydropower station, this paper introduces the layout, arched truss design and purlin of light gauge-steel roof, providing reference for design and application of similar projects.
