// Overview
The project involved the design of a roof-mounted steel canopy structure to support solar panels installed above an existing building. The scope included structural analysis of the supporting frame, assessment of imposed loads on the existing structure, and development of connection details to ensure safe load transfer. Wind load assessment was a key component of the design, considering the elevated position of the panels and exposure to coastal conditions. The design also incorporated a corrosion protection strategy suitable for the environmental conditions to ensure long-term durability.
// The challenge
The primary challenge was designing a structure that could safely transfer loads to an existing building not originally designed for additional rooftop loads. This required careful evaluation of load paths and support conditions. The coastal environment introduced high wind exposure and increased risk of corrosion, requiring enhanced durability considerations. Additionally, the design needed to remain lightweight and efficient to minimise additional loading while maintaining structural performance.
// The outcome
A robust and efficient steel canopy structure was delivered, optimised for both structural performance and constructability. The design ensured safe load transfer to the existing building while addressing wind loading and environmental exposure. The incorporation of appropriate corrosion protection measures supports long-term durability, making the structure suitable for demanding coastal conditions.
