摘　　要：平板型张力集成体系是比较适合于工程应用的张力集成体系的结构形式.预应力的施加方法和过程会影响到最终的预应力分布.本文针对两节点相对强迫位移施加刚度的方法进行了分析,对该类结构体系的预应力变化规律以及在各种影响因素下的变化规律进行了详细的归纳和总结,在平板型张力集成体系的预应力分析方面做了一些有意义的尝试.The flat tensegrity system is a kind of structual form,which is more suitable for engineering application.The method and procedure of introducing prestress will affect the final prestress state of the structure.In this paper one useful method to introduce prestress using the method of forced displacement between two nodes is presented.The prestress changing rules of the system are also summarized which is helpful to study the mechanical property of flat tensegrity systems in datail.
