Life-cycle optimisation in earthquake engineering
An overview is presented of life-cycle optimisation in the establishment of reliability- and performance-based seismic design requirements for multi-storey systems. Alternative approaches are presented for the development of seismic vulnerability functions that do not require the determination of lateral deformation capacities. The influence of damage accumulation on the evolution of the seismic reliability functions is discussed, and some results are presented about the sensitivity of the seismic reliability and performance functions to the contribution of energy-dissipating devices to the lateral strength and stiffness of multi-storey frames. The process of structural damage accumulation resulting from the action of sequences of seismic excitations is taken into account in the assessment of life-cycle system reliability and performance, and in the formulation of reliability and optimisation criteria and methods for the establishment of structural design requirements and for the adoption of repair and maintenance strategies. Problems related to the transformation of research results into practically applicable seismic design criteria are briefly discussed. Several illustrative examples are presented.
