The modified Newton-Raphson with load control and displacement control methods isused to trace the structural response up to collapse.

The linesearch technique has been included to improve the rate ofconvergence in the analysis of reinforced concrete slabs.

From comparison of the computed and observed responses conclusions have been drawn which have implications for the general application of finite element analysis to geotechnical problems; parameter selection or numerical analyses; and the essential requirements of the soil model for predicting soil behaviour.

In chapters 3, 4 and 5 the main concern of analyses was to reproduce the observed settlements, lateral displacements and excess pore water pressures induced within the soft clay foundations.

The analysis cantrace the load-deflection response up to collapse includingsnap-through behaviours.

The program allows for the yielding ofsteel and the cracking and crushing of concrete.However, in chapters 4 and 5 predictions of lateral displacements and excess pore water pressures were poor.More accurate estimates of the observed lateral displacements and excess pore water pressures were obtained using empirical methods (hand calculations).The elastic buckling loads obtained for plates with andwithout openings and under different edge loading conditions havebeen compared with the analytical and numerical results obtained byother investigators using different techniques of analyses.Goodcorrelation between the results obtained and those given by othershas been achieved.By continuing to use this site, you consent to the use of cookies.We use cookies to offer you a better experience, personalize content, tailor advertising, provide social media features, and better understand the use of our services.A cheapest stable nonconforming finite element method is presented for solving the incompressible flow in a square cavity without smoothing the corner singularities.The stable cheapest nonconforming finite element pair based on is the finite element space of piecewise constant pressures with the globally one-dimensional checker-board pattern subspace eliminated.Analyses primarily concentrated on the use of the modified Cam clay soil model.Particularly in chapter 3, the ability of modified Cam clay to predict the essential elements of the foundation behaviour was reasonable.
