摘　　要：在高阶单步拟动力试验算法基础上,将具有无条件稳定、优良的算法阻尼特性、无超越现象、截断误差为△t^5的高阶单步法用于拟动力子结构试验,提出了高阶单步拟动力子结构试验算法.根据拟动力子结构算法数值模拟分析结果,以及底部框支配筋砌块短肢砌体剪力墙足尺模型结构试验结果,证实了高阶单步算法的可行性和优越性.Based on the study on the high order single-step pseudo-dynamic testing algorithm, the high order single step algorithm featuring unconditionally stable good algorithm damping properties,a lack of transcendental phenomenon, and △t^5 of truncation error is applied to substructure pseudodynamic testing, and then the high order single step substructure pseudo-dynamic testing algorithm is proposed. The feasibility and superiority of the algorithm are verified with the numerical simulations of the substructure pseudodynamic testing algorithm comparison and the testing results of the full-scale frame-supported reinforced concrete shortlimb masonry shell wall structure.
