圆形钢管混凝土柱偏压性能研究

STUDY ON ECCENTRICITY OF CIRCULAR CONCRETE-FILLED STEEL TUBULAR COLUMN

通过系统的试验设计,探究了圆形钢管混凝土柱在不同偏心距和加载质量下的承载能力、变形性能和破坏模式。结果表明,偏心距和加载质量对圆形钢管混凝土柱的性能影响显著,表现为承载力的非线性增长、变形性能的复杂变化以及破坏模式的多样性。研究结果为理解圆形钢管混凝土柱在偏心受压条件下的力学行为提供了依据,并为结构设计和安全评估提供了重要的参考价值。

Through the systematic experimental design,the bearing capacity,deformation and failure mode of circular concrete-filled steel tubular column under different eccentricity and load conditions were explored.Results show that the eccentricity and load have significant effects on the performance of circular concrete-filled steel tubular columns,which are manifested as nonlinear increase of the bearing capacity,complex changes in deformation performance and diversity of failure modes.These results provide an experimental basis for understanding the mechanical of circular concrete-filled steel tubular columns subject to eccentric compression,and also an important reference for structural design and safety evaluation.
