From the reviews:
This recent book ... deals with all aspects of sensitivity analysis for structural systems. ... One highlight is the elaboration on the differences in working with the reduced stiffness matrix and with the generalized stiffness matrix. ... There are many other details that readers will appreciate when using the book ... . The book is a welcome, up-to-date addition to the literature in the area and it is a must as a reference volume for any research group working in sensitivity analysis and design optimization.
