Performance-based optimization method for structural topology and shape design

Continuum topology and shape optimization has received considerable attentions in recent years. However, no performance-based optimality criteria are used in existing continuum topology optimization methods to obtain the global optimum. In addition, existing methods mainly focus on theoretical aspects rather than practical applications. This thesis presents the systematic development of a Performance-Based Optimization (PBO) method for topology and shape design of continuum structures subject to stress, displacement and overall stiffness constraints, and its practical applications to stuctural engineering
