Summary

Reserve strength, residual strength, redundancy and collapse mechanisms are important considerations when performing reliability assessments of structures. This paper describes work being undertaken at the Steel Construction Institute (SCI) to provide a means of quantifying these issues. Detailed strength modelling of structures, up to and beyond ultimate load, will be achieved by integrating component response characteristics for both member and joint behaviour, with provision for the interaction effects which occur in complex structures.

Included in this paper is a survey of recent background work and test programmes which have been carried out to determine the ultimate strength of tubular frames. Development work at SCI, under funding from oil and gas operators and the UK Department of Energy, covers testing of large scale tubular frames and components, and the production and calibration against the test data of a nonlinear analysis program for performing full collapse analysis, member redundancy studies and optimisation studies, as necessary in a reliability study. It is also intended that the system will be used in the decision making process for cost effective design, inspection, maintenance and repair of tubular steel structures.
