Footpath continuous bridge structure experiment teaching system variably strides

The utility model discloses a footpath continuous bridge structure experiment teaching system variably strides, the detecting system who includes the continuous bridge emulation body, load device and be used for going on under different load operating modes detecting, the continuous bridge emulation body is for variably striding the footpath structure, and it includes the beam bridge body, set up and form the supporting in the support at beam bridge body both ends and coupled beam pontic and can follow bridge at least one pier stud to reciprocating motion, detecting system includes and strides the footpath underbeam pontic amount of deflection detection device that the detection device and going on the amount of deflection of meeting an emergency that detects detected that meets an emergency to the difference, can make the student can know the basic configuration characteristic of continuous bridge in the classroom to through increasing the load, to understand atress characteristic and the internal force distribution situation of continuous bridge under loading, and can carry out the experiment of quiet power at the indoor continuous bridge emulation body of striding the footpath combination to the difference, the internal force distribution situation that made up in the footpath is striden to analysis continuous bridge difference, to how confirming reasonable limit midspan ratio enhancement perceptual knowledge.
