钢管钢纤维自应力自密实柱轴心受压性能
Compressive Behavior of Steel Tube Columns Filled with Steel Fiber Reinforced Self-stressing and Self-compacting Concrete
摘要
Abstract
Six short columns, including two steel tube short columns filled with steel fiber reinforced self-compacting concrete, one steel tube short columns filled with self-stressing and self-compacting concrete , one steel tube short columns filled with self-compacting concrete and two steel tube short columns filled with steel fiber reinforced self-stressing and self-compacting concrete, were concentrically loaded to failure. The variables investigated are self-stress and steel fiber volume percentage. The results indicated that the self-stress can significant enhance the load carrying capacity of the specimens, but lead to obvious decrease of their deformability. Adding steel fiber not only relieves the decrease of deformability caused by self-stressing, but also effectively improves the confinement of steel tube to concrete.关键词
