This paper introduces a computer system devised to assist the steel fabricator through the various stages of a steelwork contract. Working documents for estimating, material ordering, fabrication, and erection are produced. The system can handle beam and column buildings of irregular layout and size, and has been fully operational for some time. The volume of work being processed is currently at an average rate of 10 000 t/annum.
Dr. J. M. Lovegrove: I should like to describe some work that is at present being carried out in the Civil Engineering Department of all of Southampton University. The work is supported by grants totalling £60 000 from the Science Research Council, extending over 5 years from September 1976.
This paper outlines some of the basic steps taken and factors to be considered in the design of lattice steel towers. The TOWER computer system is described. This is an interactive computer system comprising three programs developed especially for the structural analysis, design, and automatic drawing of self-supporting lattice steel towers. Details are given of the scope of the computer system and of its method of operation as an interactive design aid. The designer can take advantage of a wide range of available program options to define the structural system, the environmental loadings, and the strength and serviceability design criteria. The benefits of the computer system include considerable savings in overall design time and improvements in the accuracy of applied loadings and member forces for design.
