Limit analysis is concerned with the development of efficient methods for computing the collapse or limit load of structures in a direct manner. It is therefore of intense practical interest to practicing engineers. There have been an enormous number of applications in metal structures. Applications of limit analysis to reinforced concrete structures are more recent and are given in two recent books (W.F. Chen, 'Plasticity in Reinforced Concrete', McGraw-Hill, 1982; M.P. Nielsen, 'Limit Analysis and Concrete Plasticity', Prentice-Hall, 1984). Applications to typical stability problems in soil mechanics have been the most highly developed aspect of limit analysis so that the basic techniques and many numerical results were summarized in the 1975 book by Chen entitled 'Limit Analysis and Soil Plasticity', Elsevier. About 250 pages in this 1975 book were devoted to applying limit analysis to the well-known 'classical' stability problems in soil mechanics: bearing capacity of footings, lateral earth pressure problems, and stability of slopes. Many limit analysis solutions were presented and compared with solutions from conventional limit equilibrium analysis and slip-line solutions. In several instances, especially in bearing capacity problems, such a level of reliability and completeness was achieved that limit analysis solutions were given in comprehensive graphs and tables greatly facilitating the practical application of the results.
