［摘要］近年來世界各地設(shè)計(jì)建造了許多優(yōu)秀的大跨度結(jié)構(gòu)。體育場(chǎng)館、會(huì)議中心、劇院和展覽廳建筑的各種功能需求對(duì)大跨度屋蓋體系提出了大量要求。為滿足建筑建成后的使用功能要求，應(yīng)采用合理的結(jié)構(gòu)分析及設(shè)計(jì)方法以確定合適的結(jié)構(gòu)跨度。介紹了印度建成的一些大跨度或中等跨度的鋼和混凝土屋蓋體系項(xiàng)目，包括設(shè)計(jì)參數(shù)、結(jié)構(gòu)材料選擇、結(jié)構(gòu)體系選型和施工技術(shù)。由于需求量不斷增加，通常認(rèn)為跨度在15~50m之間的“中等或適中跨度結(jié)構(gòu)”更適合于發(fā)展中國家。優(yōu)秀的大跨度結(jié)構(gòu)作品的完成也需要建筑和結(jié)構(gòu)系統(tǒng)的完美結(jié)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.
Keywords:steel frames； composite structures; roofing systems
