The Navigation System for Structural Design Enabling Performance-Based Design Considering Various Value

通过基于性能的设计，设计师有了更多的灵活性。然而，人们普遍认为，设计过程是一系列妥协。设计时考虑了总造价、结构性能、可维修性和不可量化要求之间的权衡关系，以满足多种设计条件。这些冲突需求下的决策过程被描述为一个多目标优化问题。要确定所有的目标函数和约束值是困难的。有些要求很难用数字来表达。此外，现实的结构设计需要离散解。为了克服这些困难，我们提出了一种新的方法，即结构设计导航系统，它使得基于性能的设计能够考虑不同的价值。我们总结了结构设计导航系统的研究成果如下：1.辅助决策…的三维框架优化设计的特点结构设计中的更多过程2.考虑实际设计条件的框架优化设计方法3.在建筑中加入被动阻尼器的有效设计方法4.建筑框架稳健优化设计方法在实际结构设计中的应用5.使设计者能够操纵性能指标的直接性能操作法我们所提出的方法的学术特点、创新和创新点如下：1.我们提出的方法是基于新的概念，使设计者能够控制所有的性能指标。无论性能类型如何，该方法都能有效地找到设计。通过这种方法，设计者可以针对结构设计条件进行协作，以找到更合理的设计。2.考虑到许多现实的设计条件和不可量化的要求，很难设计出满足动力响应的约束。本文提出的方法可用于此类基础隔震结构和设置被动阻尼器的框架结构的设计。较少

By Performance-Based Design designers have more flexibility. However it is widely recognized that the design process is a series of compromises. Design is made considering trade-off relations between total cost, structural performances, repairness and unquantified requirements to satisfy multiple design condition. These decision making process under conflicting requirements have been formulated as a multiple objective optimization problem. It is difficult to determine all the objective functions and the constrain values. Some requirements are hard to express numerically. Furthermore discrete solution is needed for realistic structural design. In order to overcome the difficulties, we propose a new method, namely The Navigation System for Structural Design, which enables Performance-Based Design considering various value.We summarize the research results about The Navigation System for Structural Design as follows :1.The characteristics of optimal design of 3d frames for aiding decision … More making process in the structural design2.The optimum design methods of building frames enabling to consider realistic design conditions3.The effective design methods of a building added passive damping device4.The robust optimum design methods of building frames applied to the practical structural design5.The direct performance manipulation method enabling the designers to manipulate performance indicesThe academic characteristic, creative and pioneering points of our proposed method are as follows :1.Our proposed methods are based on new concepts that enable the designers to control all the performance indices. The method finds the design efficiently regardless of performance type. By using this approach designers can collaborate to find more rational design in view of structural design conditions.2.It is difficult to design to satisfy the constraints of dynamic response considering many realistic design conditions and unquantified requirements. Our proposed methods can be applied to design such base-isolated structures and building frames added passive damping devices. Less
