The benefits of light steel framing and modular construction in relation to
structural robustness are:
- Light steel framing and modular construction provide robust structures that satisfy the Building Regulation requirement for avoidance of disproportionate collapse.
- Robustness is provided by multiple members with a high degree of inter-connectivity.
- Load bearing walls are produced that distribute loads rather than relying on discrete load bearing columns.
- Light steel frame construction generally has lateral bracing distributed throughout the structure.
- The form of construction creates multiple load paths which mean loads can be transferred around areas of local damage.
- Light steel structures are capable of resisting high wind loads.
- Modular construction can be designed so that complete modules can be removed without the building becoming unstable.
- Light steel buildings are commonly used in seismic zones with a good record for surviving earthquakes and flooding.
- The lightweight nature of the construction means that if any local damage does occur, debris loading is considerably less compared to heavier construction materials.
- Steel is a ductile material which is able to sustain significant deformation without detrimental loss of strength.
