Commission 1
Performance and Requirements Objectives 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.

Similarly, it is one of the main obligations for the regulators to provide the framework for the evaluation of safety across types of infrastructures and across industries. However, safety of individuals and associated welfare of the public come at a price. Requirements to safety and acceptable risks to life and health have strong implications on the present allocation of societally shared resources and trade-offs play a crucial role for sustainable societal development. Thus, to ensure adherence to safety, while facilitating optimal and sustainable allocation of publicly shared resources, it is paramount to establish and act in accordance with an adequate rationale. It has for long time been clear to professionals dealing with safety and risk that such a commonly accepted rationale has not yet been implemented. Presently a variety of incoherent regulations, standards and codes are applied - and what is understood as best practices of safety management may not always be justified with respect to an adequate level of safety, where the resources used are in balance with objectives of the society. In consideration of the significance of safety regulation, the common rationale is evidently missing. The motivation for this workshop is, with a focus on safety management within civil engineering, to bring together the main stakeholders: regulators, public authorities, planners, designers, owners and operators infrastructures as well as leading experts from industry and academia, with the objective to pin down the main reasons for the present situation, to agree on the actions needed to correct the situation and finally on the allocation of responsibilities for implementing these. The workshop is organized by IABSE Commission 1 and JCSS as a structured and facilitated discussion, inspired by targeted presentations from a few selected stakeholders. Experts and stakeholders are specifically invited for contributing and participating in the discussion. The presentations and the discussion at the workshop will be documented in the proceedings. The main emphasis of the workshop is to establish a consensus on how to proceed towards a common understanding and methods for the assesment of risk acceptance in engineering practice and standardisation.
