AN EXPERIMENTAL STUDY ON HYSTERETIC BEHAVIOR OF REINFORCED CONCRETE ULTRASHORT COLUMNS AND STEEL REINFORCED CONCRETE ULTRA-SHORT COLUMNS
-
摘要: 与普通框架柱相比,超短柱的抗侧刚度较大,在地震作用下将承担较大的水平荷载。由于钢筋混凝土超短柱在水平地震荷载作用下的变形能力和延性很差,破坏模式通常为剪切破坏,从而导致框架结构的整体抗震性能下降。结合实际工程对2根钢筋混土超短柱和2根型钢混凝土超短柱的滞回性能进行了试验研究,并结合现行国内外规范给出了合理的设计建议。Abstract: Ultra-short columns will endure more lateral load because of their large stiffness compared to general columns in an earthquake.The deformation behavior and ductility of extremely short columns are poor due to the shear failure,which decreases the seismic performance of the concrete structure.The seismic performance of four ultra-short columns(two reinforced concrete ultra-short columns and two steel reinforced concrete ultra-short columns) are studied in this paper.The rational suggestions on design are proposed according to the current codes both at home and abroad.
