Cable-Membrane (Tensile) Structure

This structure clearly illustrates the synergy between its two core components: cables and membranes. The membrane is tensioned and anchored to supports via steel cables (ridge, valley, and edge cables).

Self-Balanced Tensile Structure

"Self-balancing" describes a structure whose internal tension and compression forces achieve equilibrium, minimizing horizontal thrust on supports. The cable dome exemplifies this, using continuous cables and discrete struts.

Hybrid Tensile Structure

"Hybrid" refers to the combination of different structural systems, such as rigid frames and flexible cable-membranes.

Tensile Structure

Lightweight yet strong, reaching beyond limits

The tensile structure is the most classic and artistically expressive form of membrane architecture, as well as the most technically challenging category. It represents the core essence of membrane structure design: utilizing the tension generated by a flexible membrane under prestress to shape forms and bear loads.

A tensile structure is an architectural system that forms a stable three-dimensional curved surface by applying prestress to a flexible membrane, which is then tensioned and secured through a series of rigid boundary elements (such as masts, arches, and ring beams) and flexible boundary elements (such as steel cables and cable nets).

Its core principle is “tensile forming,” meaning the membrane material itself lacks stiffness and shape and must be “stretched tight” through externally applied tension to achieve a defined form and load-bearing capacity. This stands in sharp contrast to pneumatic structures, which are formed through “inflation and expansion.”
