NON-LINEAR ANALYSIS OF STRUCTURAL SYSTEMS OF STEEL AND CONCRETE

This thesis was submitted as partial fulfilment of the requirements for the degree of master of engineering science, university of Melbourne, 1977. In order to analyse the complete behaviour of structural systems of steel and concrete under load, it is necessary to consider a number of non-linear effects. Of major importance is the stress redistribution which follows the tensile cracking of concrete. In this dissertation a literature review is presented of possible solution procedures and it is shown that the finite element method is a convenient approach to performing the desired analysis. A concrete material model finite element is developed for inclusion in the general non-linear analysis program, nonsap. To enable concrete- steel reinforcement bond to be considered, a linkage finite element has also been programmed. This element is found to be useful for modelling a number of different phenomena associated with steel-concrete systems. Results are given for the analyses of three different structures and of investigations into the sensitivity of the solution procedure. It is shown that the developed finite element program satisfactorily models the non-linear behaviour under monotonic loading of the systems investigated. General recommendations are made regarding the most suitable approach to modelling a system and the parameters likely to be of importance in an analysis are identified. An outline is given of areas which require further research. (TRRL)
