Abstract

The objective of this study is to propose the new design formula for ultimate strength and allowable strength of slender concrete filled square steel tubular columns subjected to axial force and bending moment. This new formula is based on the full plastic strength, and has no slenderness classification between short, medium, and slender columns which is used in the current CFT recommendations. The proposed ultimate strength agreed very well to the analytical results whose parameters are material strengths, moment gradient ratio, column length - depth ratio and corresponded to the previous experimental results.

方钢管混凝土梁柱在轴力和弯矩作用下的强度

本文的研究目的是提出细长方钢管混凝土柱在轴力和弯矩作用下的极限强度和许用强度的新设计公式。这个新公式是基于全塑性强度，并没有长细分类之间的短，中，和细长的柱在目前的CFT建议中使用。所提出的极限强度与材料强度、弯矩梯度比、柱长深比等参数的分析结果吻合较好，并与前人的试验结果相吻合。

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
