STRUCTURAL DESIGN BY SINGULAR IMBEDDING

The singluar imbedding approach presented has some advantages over a conventional design method in designing a structure to meet specified requirements, especially in the computational aspects. Instead of having to iterate on analysis and design until the requirements are met, a single computational procedure is used when the singluar imbedding approach is used. The approach also provides flexibility on designing variable members to meet the constraints imposed on the structure. Hence, the designer will save time and will have a choice in selecting properties for the variable members. The approach has been shown to be efficient for designing a structure to meet a set of specified requirements. The class of problems which is best suited to this approach is the following: given a structure with prespecified topology and geometry, with a significant fraction of members prespecified, and a relatively small number of constraints, design the remaining variable members to yield the desired performance. This class covers a sufficiently wide range of problems to make the method attractive. As an example, in a tall building, lateral displacement or drift limitations may be imposed, and many members may already be prespecified, either because of gravity loading requirements or other considerations, such as repeated use of a single structural shape to reduce costs.
