Abstract:Stirrup design method of “studs and multiple-spacing-stirrups crossing the steel web”was proposed to reduce the construction processes of steel-reinforced concrete short columns with large height-width ratio employing arrangement of stirrups crossing the steel web as well as opening, to shorten the construction period and reduce the construction cost. The method was adopted to conduct experimental study on seismic performance to design the steel-reinforced concrete short columns with large height-width ratio. Research shows that the steel-reinforced concrete short columns with “studs and multiple-spacing-stirrups crossing the steel web” have good bearing capacity, plastic deformation capacity and energy dissipation capacity, and meet the seismic performance requirements. Finally, the effectiveness and feasibility of the proposed method were verified by the practical engineering application.
Keywords:steel-reinforced concrete short column; multiple stirrup spacing; stirrup; stud; seismic performance; large height-width ratio
