The Structural Engineer, Volume 67, Issue 15, 1989
Mr Stevens mentions that we are equipped by our training and education to analyse circumstances and solve problems-a quality that enables us to both manage and lead. There is no doubt as to the truth of his statement. But why, then, are we still performing subordinate roles? Mr Stevens suggests that this may be due to our having lost the charisma, the eloquence and the public image of our great pioneering predecessors. Mr Cheng Chee Chai
Any structural engineer involved in larger scale commercial developments cannot have failed to notice the proliferation of unusual terms and conditions of engagement for an engineer’s duties. While some clients still seem to be content to use the ordinary standard forms, many other clients now seem to have departed from them completely. While speculation about the cause of this phenomenon might be idle, there must be a reason for it. Some might say that the reason is that the inadequacy of the JCT forms has caused owners and developers to look hard at all their forms of contract; others, more cynically, may conclude that it is the direct result of firms of lawyers setting up ‘construction law departments’ which then have to find something to do.

The transfer matrix method is applied to the elasto-plastic analysis of coupled shear walls resting on rigid or flexible foundations. The development of the non-linear formulation follows that of the corresponding linear problem with the load applied incrementally and the material behaviour monitored and updated at each load step. Emphasis is laid on reinforced concrete as a structural material, so that sectional properties are evaluated on the basis of stress-strain curves for each of its constituents. Numerical solutions of examples are presented at the end to demonstrate the accuracy of the proposed technique. I.A. Akintilo and S. Syngellakis
