某钢管桁架人行栈道荷载试验方法研究

Study on load test method of a steel pipe truss pedestrian trestle

为了解钢管桁架人行栈桥的力学性能,结合某跨度为12.34 m钢管桁架人行栈道工程,系统分析了钢管桁架人行栈桥的静力荷载试验的检测方法,并对栈桥进行静力载荷试验。研究结果表明,该栈桥在试验过程中处于线弹性阶段,未出现明显异常。该检测方法节约材料、减少工期、操作简便,对同类型桥梁的检测有参考价值。

In order to understand the mechanical behavior of steel pipe truss pedestrian trestle,the detection of load test of steel pipe truss pedestrian trestle was conducted and the method was conducted and systematically described combined with a steel pipe truss pedestrian trestle project with a span of 12.34m.The study shows that the steel pipe truss pedestrian trestle worded in elastic behavior during the test.The detection method could save materials,reduce construction period and operate easily.It had reference value for the detection of the same type of bridges.
