Abstract |
The purpose of this study were evaluated to flexural and bond performance by sectional area and geometry change through bond and flexural test of a structural synthetic fiber. Six deformed structural synthetic fibers were investigated and pullout and flexural test was conducted. Included parameters is three different geometries of fiber and two of fiber sectional area. The test result shows that the cycles and amplitude of structural synthetic fiber increased, pullout load and pullout fracture energy decreased and flexural strength increased, if sectional area is same. The sectional area increased, pullout load and pullout fracture energy increased and flexural strength decreased, if cycles and amplitude of structural synthetic fiber is same. Based on test results, structural performance of the concrete could know that is influence by pullout performance of fiber as well as various factor (fiber number, material properties etc)
