【提要】 使结构安全适用、经济合理，是结构工程师的任务和责任。根据长期的工作体会阐述了结构设计的理念、结构设计的工作方法、影响结构的综合技术经济指标的因素。从概念设计的观点出发，介绍抗震设计中遵循的原则，提高房屋结构的抗震性能的措施，以及实际工程中结构单元的划分，结构类型的选择，楼屋盖方案
的比较，地基基础处理等。通过这些介绍，希望能对工程师做好结构设计有所启迪。

Elementary Introduction to Structural Design/Kong Yasha,Xie Dingnan(China Architecture Design & Research Group,Beijing 100044,China)
Abstract:The safety of structural design must be ensured. How  to unify dialectical relation between safety in use and economy in cost is the mission and duty of structural engineers.According to long period experience of work,it expatiates on the principle of structural design,the structural design method,the concept of general economic and technical index.From many actual projects,it introduces the principles followed in the seismic design and the measures  to increase the seismic ability of buildings,the demarcation of structure units,the choice of structure types, the comparison of the floor and roof analy
sis schemes,and the foundation treatment instances of some projects.All these introductions are hoped to provide revelation to structural design.
Keywords:design concept; conceptual design; general economic and technical index; structure unit; structure member; dissipative member; nonstructural member
