Matrix formulations are suitable for computer implementation and can be applied to two major methods of structural analysis: the flexibility (or force) method and the stiffness (or displacement) method. This ch

A nu-merical example is analyzed, which indicates that the failure probability is different for different use life and the influence of dead and fatigue loads on reliability of the structural system is different as well. This method of reliability analysis, in the pa-per, is better than the ...

Matrix perturbation theory (MPT) is widely used in sensitivity analysis and reanalysis of structural eigenvalue problems when small changes are imposed on parameters. However, the conventional MPT based on the finite element method is only applicable to the cases with small parameter variations, and ...
There is a more general method, which we can use to continue solving past a point of instability. In this method, we first define an arbitrary quantity that is known to monotonically increase and then add an extra equation that solves for the corresponding value of the prescribed load or dis...

The step in which the velocity correction is ‘improved’ is an iterative method for reducing the residual at the current level that has the property of smoothing the error strongly at the current mesh scale. At each level, these smoothing operators reduce the residual most strongly on the scal...
