Performance and Requirements
Performance is regarded as a measurable result (either qualitative or quantitative) of the structural behaviour and properties within the whole life cycle.
Safety is understood as structural reliability against unwanted events in relation to the structures.
Requirements are defined as guidelines or the set of rules to comply with when dealing with design of new structures. It also involves decisions relevant to existing structures with respect to performance and safety.
The commission tackles critical topics on structural performance and safety of buildings, bridges, tunnels, towers as well as special engineering structures, and covers its requirements, in the design phase and beyond.
The evaluation of structural performance under various actions, both man-made and environmental, includes analytical and experimental approaches for assessment of safety, durability and reliability, security and serviceability, availability and maintainability. C1 will incorporate lessons learned from practice, from collapses and from successes, in creation of applicable guidelines for maintaining structural performance.
