Abstract

The effects of cyclic loading protocols on the structural performance of rectangular hollow-section members, such as the ultimate resistance determined by local buckling and the degradation behavior, are clariﬁed through structural tests and elasto-plastic numerical analyses based on the ﬁnite element method. The material constants of the Chaboche model and the subloading surface model were identiﬁed using cyclic coupon tests to simulate the structural tests by the ﬁnite element method, and the analysis of rectangular hollow-section members subjected to bending shear was performed. Finally, evaluation formulae for the structural performance are proposed based on parametric numerical analyses.

加载方式对箱形截面钢构件局部屈曲劣化行为的影响

通过结构试验和基于有限元法的弹塑性数值分析，阐明了循环加载方案对矩形空心截面构件结构性能的影响，如局部屈曲决定的极限抗力和退化行为。采用循环副板试验模拟结构试验，确定了Chaboche模型和次荷载面模型的材料常数，并对矩形空心截面构件进行了弯曲剪切分析。最后，提出了基于参数数值分析的结构性能评价公式。

期刊介绍： The Architectural Institute of Japan’s Journal of Structural and Construction Engineering aim to pursue theories for building and maintaining pieces of architecture as well as the cities or areas surrounding them, and to accumulate and systematize the knowledge needed to put those theories into practice. The Journal of Structural and Construction Engineering focuses on research results in the specific fields of “building materials and construction” and “structures.” Accordingly, it compiles articles in the following areas, disseminates relevant information, and hosts discussions: ・Concrete, steel, and inorganic materials ・Timber and organic materials ・Finishing materials ・Construction and quality management ・Applied mechanics ・Loads and reliability on structures ・Building foundations ・Timber structures ・Steel structures ・Reinforced concrete structures ・Shell and spatial structures ・Engineering seismology and structural dynamics ・Other composite structures
