摘　　要：以超静定桁架结构为背景研究了自适应结构的承载能力 .探讨作动器和杆单元的共同工作 ,用以进行结构分析和控制结构承载能力 .后者意指通过作动器的主动变形调控结构的内力分布以获得更加合理的工作状态 .The capacity of bearing loads for the adaptive structure of statically indeterminate truss is investigated. The cooperative work of the actuator and the bar element is explored to perform the structural analysis and to investigate the possibility of controlling the capacity of bearing loads of the structure. The latter means that a distribution of internal forces at the structure is adjusted by the active distortions of actuators to obtain more reasonable working state.
