摘要
发展和推广预应力混凝土结构是改善和提高结构使用功能 ,节约钢材和节省能源的重要措施 ,它适用于建造跨度大、荷载重的承重结构 ,并具有自重小 ,使用性能好的优点 ,介绍了一般无粘结预应力混凝土结构设计和施工中的常见问题及处理方法。指出无粘结预应力混凝土结构设计程序非常适用。
Development and spread of prestressed concrete str ucture is an importa nt measure to improve and enforce the utilization function of structure, economi ze the steels and energy sources. It applies to constructing the bearing structu res with the great load and large span. It has advantages of minor self?gravity and sound performance. With rapid development of high?performance steel strand i n our country, development and application of the new material will definitely p romote development and application of the prestressed technology in our country. The writer briefly introduces common issues and solutions in the design and con struction of cohensionless prestressed concrete structure.
