| Abstract: | An application of multi-level optimization technique for structural design of tall buildings is presented. The strategy of optimization analysis is conducted by considering the structural behavior of a building at three levels, namely, element-by-element, sub-structural and global levels. In addition to the live and dead loads, both the wind and earthquake loading are considered in accordance with the Chinese design codes. From these, constraint requirements are formulated by including member's strengths, local and global buckling, maximum and inter-story drift limits. The building types treated include steel frames, concrete frames, shear walls, and hybrid structures (concrete and steel). In the paper, mathematical formulations of the optimization problem with constraint conditions are given. Two demonstration examples, i.e. a steel braced-frame and hybrid structure, are included to illustrate the utility of the methodology presented. | |
