are not intended for the design of optimal structures. In the field of structural engineering, the use of numerical opti-mization techniques to aid design dates back to at least 1956 when linear programming was used to optimize frame structures based on plastic design theory [Heyman 1956]. Since then, extensive

Formulation of the finite element characteristics of an elastic bar element is based on the following assumptions: 1.The bar is geometrically straight. 2.The material obeys Hooke s law. 3.Forces are applied only at the ends of the bar. 4.The bar supports axial loading only; bending, torsion, and shear

On the other hand, in Bendsoe and Sigmund [13] several exam-ples are given for the continuum topology optimization problem where beams are added by creating a long row of solid elements

Computer aided analysis and design of multi-storeyed buildings

The principle objective of this project is to analyse and design a multi-storeyed building [G + 21 (3 dimensional frame)] using STAAD Pro. The design involves load calculations manually and analyzing the whole structure by STAAD Pro. The design methods used in STAAD-Pro analysis are Limit State Design conforming to Indian Standard Code of Practice.

Modern chassis design has come a long way. At the inception of automotive industry, the chassis structures were made of a wooden frame, with wooden body panels mounted on it. Since 1900, chassis are developed from steel and aluminum sheets enabling the designers to create shapes with more freedom. It is extremely important that the chassis

Theoretically optimal bracing for pre-existing building frames

Bracing is commonly used to provide resistance to lateral forces in building structures. However, traditional bracing design approaches appear not to be underpinned by clear fundamental principles. Here, theoretically optimal arrangements of bracing members are sought for pre-existing building frames, already designed to carry gravity loads.
