square spiral stirrups

According to the method of processing ordinal hoops and the features of spiral hoop, we analyze and compare.

基于此,本文对螺旋箍筋成形机进行了研究,以期满足工程上的实际需要。

Based on the test results of reinforced concrete columns with compound spiral stirrups, the limit of axial compression ratio of the code for aseismic design of building structures(GBJ11—89) may be enlarged.

本文从设计中这一现象出发，通过限制轴压比的必要性以及放宽轴压比可能性的讨论，在试验结果分析基础上提出采用复合螺旋箍可使现行规范的轴压比限值适当放宽，可达到减小柱截面尺寸、提高柱抗震性能之效果。
