Suspended tensile systems are structures that require an integrated approach to architectural aesthetics and structural engineering. The following parameters are considered during the design process:

1. Intended Use and System Limitations

o Dimensions of the area to be covered according to the need,

o Whether the system will be continuous or modular/fragmented,

o Height limits of the building (is it an ostentatious form or a minimalist design compatible with certain elevations?)

o Whether the facades will be closed or not (open or closed system preference).

2. Technical Design Criteria

o Material Behavior: Membrane covers are designed to withstand tensile forces only, as they are prone to deform under compressive loads.

o Load Analysis: To ensure the stability of the system under static/dynamic loads such as gravity, snow, wind and rain:

            Stress distribution is optimized by applying a pre-tensioning force to the surface,

The slope and curve design minimizes the risk of water accumulation or overvoltage.

Structural Analysis and Form Finding

The most critical stage in the design of suspended tensioning systems is the “form-finding” process, which determines the equilibrium form of the cover. In this process

- Boundary Conditions: Parameters such as fixed edges, support points and prestressing force are defined.

- Analysis Methods:

1. Finite Element Method: Stress distribution is simulated by considering material non-linearity and large deformations.

2. Force Density Method: The force balance in cables and membranes is modeled mathematically.

3. Dynamic Relaxation Method: The stable form of the system is found by time-step iterations.

As a result of these analyses, the geometry that provides stability under prestressing force and meets architectural aesthetics is determined.

Engineering and Application

- Material Selection: High strength membranes such as PVC coated polyester, PTFE (Teflon) glass fiber or ETFE are selected based on UV resistance and flexibility criteria.

- Detail Solutions: Edge connections, corner details and bearings are designed to ensure safe load transfer.

- Tests: Wind tunnel tests and static load simulations are performed on prototypes to verify performance.

Conclusion

Suspended tensile systems can only succeed with the harmonic combination of architectural vision and engineering discipline. Form finding, the first step of the design, guarantees both the aesthetic and structural integrity of the structure.
