针对一实际工程的设计,介绍了一种可以实现框架结构较大空间的新型预应力整体转换结构体系。该结构体系充分考虑大空间上部结构的整体共同工作,并采用预应力与高强混凝土等技术,以较小的构件断面尺寸实现较大空间的结构转换,并且转换结构本身不影响建筑的使用功能。就这种转换结构体系的设计特点、预应力施加方案及检测等问题进行了分析探讨,供有关工程技术人员参考 In view of the design of a practical project, a new system of prestressed integral conversion structure that can realize a large space of the frame structure is introduced. The structural system fully considers the common work of the large space superstructure and adopts the technology of prestressed and high-strength concrete to realize the structural transformation of larger space with the smaller cross-sectional size of the component, and the conversion structure itself does not affect the use function of the building. This conversion structural system design features, application of prestressing and testing and other issues were discussed for the relevant engineering and technical personnel reference
