Tensile Structure for Public Areas

Tensile structures offer an unprecedented blend of a practical shelter and an iconic art as well as they have changed the concept of popular urban design. In parks, plazas and transit hubs these buildings act as long shelf-life landmarks which defend against the sun and the rain without the oppressive weight and claustrophobic mass of conventional concrete or steel roofs.

Because they feature high-tension membranes reinforced by few masts and cables, they have an airy, open-concept feel that keeps views intact and promotes natural airflow. That makes them especially suitable for amphitheatres, community gathering areas and waterfront promenades, where remaining connected to the surrounding environment is vital. But then we can examine public area tensile structures, a concept designed from an engineering standpoint to be engineered for very high longevity and low maintenance. There are most permanent installations that are made of PTFE-coated glass fibre or high-grade PVC because these are self-cleansed as a result of rain, and are very UV resistant. These membranes are quite broad and light enough to cross the ground in very small amounts with no heavier weight, a necessity for high-footfall public space such as bus stops or playground shades. Complex and geometric shapes, like saddle-curves (hypars) or radial cones, can also help architects make interesting site-specific decisions, like what covers an irregular walkway, or how to shade on a circular fountain.
