摘　　要：张拉弦钢拱架结构是一种新型的预应力钢结构体系。本文主要进行了张拉弦钢拱架结构从成形到受载的全过程试验研究。通过试验研究了结构的受力特性,特殊节点的设计及目标形状的控制方法,为张拉弦钢拱架结构的实际应用提供了试验依据。同时,本文通过试验结果与计算结果的多方对比,对理论分析及计算程序进行了验证。The stressed-arch frame is a new type of prestressed steel structure system.In this paper,the experimental research of the stressed-arch frame from form-finding to load computation was done.The mechanical characteristics of the structure,the configuration of special joints and the control method for the objective form were studied through the experiment.At the same time,the theoretical analysis method and the code program were verified by comparison with the experimental results.
