摘　　要：劲性钢构件与外包的混凝土协同受力,既能发挥混凝土优越的抗压性能,又能发挥劲性钢构件优越的抗拉性能,可减小结构构件的截面尺寸;劲性钢构件外包裹混凝土还具有良好的防腐、防火优势。针对劲性结构中问题最多的首节劲性钢柱常见问题提出防治措施。Rigid steel component and external concrete have synergy force, which could exert the excellent compressive performance of concrete and the tensile performance of rigid steel component,to reduce the cross-section size of structural component;rigid steel component coated by concrete has advantageous anti-corrosion and fire resistance. This paper proposed prevention and treatment measures for common problems of the first part of rigid column.

关 键 词：首节劲性钢柱 标高 钢筋连接
