Fundamentals of exact multi-load topology optimization – stress-based least-volume trusses (generalized Michell structures) – Part I: Plastic Design
Structural and Multidisciplinary Optimization, 2014Co-Authors: George I. N. Rozvany, Tomasz Sokół, Vanda PomezanskiAbstract:In this two-part paper, Michell’s century-old stress-based single-load truss topology optimization paper is extended to multiple load conditions. In Part I, so-called ‘optimal plastic Design’ of multi-load trusses is reviewed, which is based on ultimate (limit or collapse) load principles and requires only statical admissibility of the solution. However, its connections to ‘optimal Elastic Design’ will be explained, and these will be used in Part II for the full extension of Michell’s theory to Elastic multi-load problems, which will fill a significant gap in our knowledge.

Structural Topology Optimization: Moving Beyond Linear Elastic Design Objectives
20th Analysis and Computation Specialty Conference, 2012Co-Authors: James K. Guest, Reza Lotfi, Andrew T. Gaynor, Mehdi JalalpourAbstract:Topology optimization is a systematic, free-form approach to the Design of structures. It simultaneously optimizes material quantities and system connectivity, enabling the discovery of new, high-performance structural concepts. While powerful, this Design freedom has a tendency to produce solutions that are unrealizable or impractical from a structural engineering perspective. Examples include overly complex topologies that are expensive to construct and ultra-slender subsystems that may be overly susceptible to imperfections. This paper summarizes recent tools developed by the authors capable of mitigating these shortcomings through consideration of (1) constructability, (2) nonlinear mechanics, and (3) uncertainties.

Improved Geometric Design of Earthquake-Resistant RC Slender Structural Walls. II: Design Implications
Journal of Engineering Mechanics-asce, 2014Co-Authors: Kaustubh Dasgupta, C. V. R. MurtyAbstract:AbstractIn a companion paper, new tapered configurations are proposed of slender RC structural walls with and without enlarged boundary elements at the wall-footing junction region. On the basis of identified parametric limits and the wall response in linear-Elastic finite-element analyses, a stepwise seismic Design procedure is proposed of tapered integrated wall-footing systems with soil or rock anchors at the bottom. This incorporates a capacity Design of the plastic hinge region above the tapered portion and an Elastic Design of the tapered portion. The location of the region of seismic damage and energy dissipation in the wall is controlled by proportioning of the tapered wall-footing as per the new Design procedure.
