Project Brief

The client was facing issues with the usability of the parking area, as it had to serve a dual purpose: parking vehicles and providing passage for transferring heavy materials from the shipping area; in addition to which the height of the heavy-duty vehicles was also a major factor. To ensure smooth functioning and adequate maneuverability of vehicles, we decided to eliminate the traditional truss structure system. Instead, we opted for a cantilever truss system, which offered an unobstructed space below and better suited the functional requirements.

The Design

Parking truss design in Nilbarahi, Bhaktapur showcases our approach to maximizing space and efficiency. This design uses a rafter-purlin system that supports a 20-foot cantilever projection, allowing for an overhanging roof structure without the need for intermediate columns. The rafters serve as the primary load-bearing components, transferring the roof load to the supports, while the purlins provide horizontal support for the roof panels. To enhance the structural integrity and stability of the cantilevered system, tensile supporting members—high-strength cables or tension rods—are integrated into the design. These members are placed in tension, helping to resist uplift and counteract compressive forces, particularly at the cantilever end.

The result is a lightweight, cost-effective structure capable of supporting large spans while maintaining stability. This system optimizes material usage, reduces the need for additional supports, and ensures long-term durability, making it an ideal solution for parking structures where space is limited, and the ability to span large areas is crucial. The 20-foot cantilever projection maximizes the usable area, allowing for efficient vehicle flow and coverage while providing a sleek, modern design that is both functional and aesthetically pleasing.
