介绍了一种利用预应力拉索的新型索连体结构形式。对三种不同形式的索连体结构进行了竖向荷载作用下的受力分析和水平荷载作用下的结构抗侧刚度分析,从而揭示了索连体结构的受力特点。通过具体的算例,对两个跨度相同但分别采用刚性桁架连体与拉索连体的结构进行分析,对比两者在竖向荷载作用下的挠度和对边筒的倾覆力矩、平面内水平抗侧刚度以及地震力大小等多方面的异同。最后,阐述了索连体结构相对传统桁架式连体结构的优点,设计和施工中的要点,以及未来在工程应用中的前景。
A new type of cable connecting structure using prestressed cable is introduced. The stress analysis under vertical load and the lateral stiffness analysis of the structure under horizontal load are carried out for three different types of cable structure, which reveals the stress characteristics of the cable structure. Through the concrete example, the two structures with the same span but the rigid truss joint and the cable are respectively analyzed. The deflection and the moment of overturning of the side tube under vertical load are compared. The horizontal plane Anti-side stiffness and the magnitude of the earthquake force and many other similarities and differences. Finally, the advantages, the main points in the design and construction, and the future prospects in engineering application are discussed.
