［摘要］近年来世界各地设计建造了许多优秀的大跨度结构。体育场馆、会议中心、剧院和展览厅建筑的各种功能需求对大跨度屋盖体系提出了大量要求。为满足建筑建成后的使用功能要求，应采用合理的结构分析及设计方法以确定合适的结构跨度。介绍了印度建成的一些大跨度或中等跨度的钢和混凝土屋盖体系项目，包括设计参数、结构材料选择、结构体系选型和施工技术。由于需求量不断增加，通常认为跨度在15~50m之间的“中等或适中跨度结构”更适合于发展中国家。优秀的大跨度结构作品的完成也需要建筑和结构系统的完美结合。

Abstract:Many outstanding large span structures have been designed and built in different parts of the world in recent times. Of late, there is a great demand for large span roofs for buildings due to various functional requirements like sports stadia, convention centres, theatres, exhibition halls etc. An analytical and rational approach is needed to select an appropriate span keeping the future needs into consideration. An overview of some selected structures with large and medium span structures created in India was given. It includes the design parameters, choice of construction materials, selection of structural system and the construction techniques adopted. The concept of ‘medium or decent span structures’ in general with spans greater than 15m and less than 50m is considered appropriate for developing countries as there is demand for more number of structures in this category. There is a need for unique synthesis between architecture and structural systems to produce exciting and outstanding structures. Examples of some of the steel structures built in India are also given along with a few special concrete roofing systems are given.
