Structural optimization seeks the selection of design variables to achieve within the limit (constraints) placed on the structural behaviour, geometry or other factors; its goal of optimality defined by the objective function for specified loading conditions. The three basic features design...
This paper is concerned with the design of reinforcement in prestressed concrete beams with openings, based on the application of regression analysis to experimental data. The results, verified by tests and the finite element method, show that a new method described in the paper is simple,...
The present study addresses the issues of non-uniqueness and unidentifiability arising in structural model updating. A Bayesian probabilistic framework is used for model updating which properly handles the uncertainties due to model error and measurement noise associated with model updating....
The reduction of the number of unknowns while capturing the essential physical features in a nonlinear analysis of large spatial structures has long been a challenging task for researchers. We approach the problem of large displacement and large rotation analysis of space frame structures by...
Previous studies of the behaviour of steel column base connections are reviewed; attention is concentrated on the results from programmes of laboratory testing. Nominally pinned bases are shown to provide significant rotational restraint and to be capable of transferring quite large moments into...
