摘　　要：在简单工程系统全局代化概念基础上，提出“简单复合工程系统”抗震设计的概念与方法。此类系统是由联和并联系统经简单复合所形成的功能关系较为复杂的二级递阶工程结构。以此为对象，文中给出这类系统的全局代化模型，并指出直接利用Lagrgnge乘子法求解这类模型的有效途径。通过翔实的其例，进一步考证了所提模型与解法的精确性、揭示了简单复合系统的有关性质，为研究功能关系上更趋复杂的工程系统提供了基础，本文概念与方法可用来决策简单复合系统的工程最优投资，以及决策在总投资或总可靠度限制下系统的最优设防水平等工程应用问题。The concept and method of anti - seismic design of a simple composite engineering system are proPOsed in this paper, based on the concept of optimization of the simple engineerirtg system. The simple comPOsite systems are a two - level hierarchical system. As an object, the mathematic models and the approach of Largrange multiplier method for the systems are presented. The examples examine the accuracy of the models, and explore the properties of the systems. Combined with an enginering application, these methods can be used to find the optimal investment or reliability of the whole proect, and determine the optimal fortification level of the systems under restrainted condition of total investment or reliability.
