This manner can form continuous arrangement effect of hoop bar with less space, and be fit for concrete restricted by stirrup. It also can reduce the concrete crack arised by retortion in the region of frame column, and improve the ductility capability under the earthquake. The construction quality of frame column is improved simultaneously.

该布置方式形成连续且间距较小的箍筋布置效果，有利于发挥箍筋对混凝土的约束作用，减小各种因素可能引起框架柱扭转而在柱非加密区产生的裂缝，改善柱中部区域在地震作用下的延性性能，同时可以提高框架柱的施工质量。

Under the same situation as steel tube ratio and volumetric percentage of stirrups and so on, yield load and increases with the increasing of reinforced bar-diameter. But the variety of reinforced bar-diameter has ruleless to limited load and ductibility.
