| Abstract: | The processing method of three kinds of helical and twisted materials(steel bar,steel fiber and organic glass bar) was studied to investigate the helical reinforcement effect of helical and twisted materials.The results demonstrate that the helical reinforcement effect is appeared in all kinds of helical and twisted materials.The annular interlocking action is the primary mechanism for helical reinforcement,and the shape of the cross-section of the materials also have great influence to it.In addition,the reasonable suggestions about the design of steel fibar and using requirement of helical and twisted materials are also presented in order to popularize the application of them. |

| Keywords: | helical and twisted material helical reinforcement effect bond and anchor property shape of cross-section |
