Abstract  Object-oriented programming technology combines data and operation．This modulariz ing design method greatly facilitates the engineering design and enhances the maintainability，extensibility and code reutilization of software and makes it easily organized by offering sharing platform to program．This paper presents the object-oriented program architecture for optimal design of tensegrity cable domes，which can be adopted in pre—press optimization，section optimization，and shape optimization．Enlightened by the idea of sharing resource，the author proposes the concept of public class library and programmed three such libraries in C+ + ．This idea not only brings great convenience to subsequent program design，but saves the researchers’time
and energy by avoiding repeated work．Finally，a numerical example of Levy cable dome is given to testify the validity of this architecture．

Key words： object-oriented programming      prestress optimization      section optimization      shape optimization      class library

面向对象的索穹顶结构优化设计程序结构

面向对象化编程技术把数据和操作结合起来，这种模块化的设计思想为工程设计提供了许多便利。为程序共享提供了设计平台，使设计软件具有易于维护、易于组织、可扩展和代码可重用的优点．利用面向对象编程技术编制了张拉整体索穹顶结构的优化设计程序．该优化设计程序可以对张拉整体索穹顶结构进行预应力优化、截面优化和形状优化设计．在程序设计的过程中，受资源共享思想的启发，提出了公共类库的设计概念，并且利用C++编制了3个公共类库．公共类库的设计思想不仅大大方便了后继程序的设计，而且避免了重复劳动。节约了科研人员的时间和精力．文章的最后，给出了一个Levy式索穹顶结构模型的算例来验证程序的有效性．
