摘要: 针对轴压比、相对偏心距的变化来研究混凝土框架角柱在压弯剪扭复合受力下的延性和试件在开裂时、屈服时及极限时的抗扭刚度,通过统计分析比较,对其受力性能进行总结,为实际设计应用提供理论依据。Abstract: The ductility of a corner post for a concrete frame under combination forces of compression, bending, shearing and torsion, as well as the torsional stiffness of its specimen at cracking, yielding and ultimate state are studied according to the changes in axial pressure ratio and relative eccentricity.The forced behavior of the corner post is also summarized by statistic analyses, which provides a theoretical basis for actual design.
