Structural
Optimization
Structural Optimization is intended to supplement the
engineers box of analysis and design tools making
optimization as commonplace as the finite element
method in the workplace. This book brings the
methods of structural optimization into common usage
like those of the finite element method. Providing the
structural engineer with the right analysis tools and
optimization tools.
Drawing upon years of practical experience and using
numerous examples and illustrative applications, Keith
MacBain and William
Spillers
discuss:
•
Structural optimization and the methods of nonlinear
programming such as
Lagrange
multipliers, Kuhn-
Tucker conditions, and calculus of variations
•
Solution methods for optimization problems
emphasizing the classic method ot linear
programming and the method of sequential linear
programming
•
Using sequential linear programming together with
the incremental equations of structures as a general
approach tor structural optimization.

Included is a CD-ROM packed with Microsoft Excel,
MATLAB ,
and FORTRAN (IMSL) routines, and
а
DLL
with linear programming capabilities that will be
invaluable to readers.
Structural Optimization will be of interest to structural
engineers, mechanical engineers, aerospace engineers
and architects, particularly those who use the finite
element method and want to include optimization in
their designs.
