摘要
密配圆形螺旋箍筋的钢筋混凝土圆柱在外荷载作用下表示了良好的力学性能。本文研究了外荷载作用下圆柱构件中圆形螺旋箍筋的受力机理，得出了圆形螺旋箍筋和受压区混凝土间存在着良好的粘结性能，圆形螺旋箍筋不仅发挥对受压区混凝土横向约束作用，而且也发挥了抵抗外剪力的作用，这两种作用相互独立、互不影响等结论。
The reinforced concrete circular colunms with circular spiral reinforcement show excellent behavior when subjected to loads. This paper studies, the reinforcing mechanism of circular spiral reinforcement in reinforced concrete circular columns which are subjected to loads, reaching the conclusion that there is good bond behavior between the circular spiral reinforcement and the compressive concrete in the compressive zone of the column section, and that the circular spiral reinforcement not only has the ef...
