[摘要] 在传统的结构设计中对构件的优化调整往往凭经验，这样做效率很低且结果往往不够理想。本文介绍了一种尺寸优化方法，是通过有限元程序来实现的，这种方法可以对构件进行自动优化并得到每个构件的敏感性，从而在构件调整时做到有的放矢。本文以深圳京基金融中心超高层结构为例详细介绍了这种优化方法。

Abstract: The traditional structure design always relies on experiences for the structural optimization. However, this optimization method is inefficient and not ideal, particularly for the super high-rise building. This paper introduces a new method of size optimization, using the finite element software Optistruct. Using the new method optimization is completely automatic and also can get every members sensitivity, and then get the ideal result of structure adjustment eventually. The application of the new optimization method is presented in details based on an example of a super high-rise building.
