Abstract

A bimodal tram is a new design vehicle introduced to improve a current transportation system, and it has advantages of a bus and a subway. A pipe truss bridge, an exclusive road of the bimodal tram, is constructed for introduction of the bimodal tram. An analysis of dynamic response characteristics is required because this new bridge has never constructed before. A speed increasing test on the pipe truss bridge was conducted with attaching a sensor to bottom of the bridge. Also, Dynamic response characteristics were analyzed by measuring displacements, the maximum vertical and horizontal acceleration about the new bridge through the experiment.

바이모달트램(Bimodal tram)은 현행 교통체계를 해소하고자 도입되는 신형식 차량으로 버스와 지하철의 장점을 지니고 있는 시스템이다. 이러한 차량의 도입으로 인해 전용선로인 파이프트러스교가 건설 되어지는데 기존에 시공되지 않은 새로운 형식의 교량으로 이에 대한 동적응답 특성에 대한 분석이 필요하다. 본 연구에서는 바이모달트램의 전용선로인 파이프 트러스교에 대하여 교량 하부에 센서를 부착하여 차량의 주행실험을 실시하였다. 또한, 실험을 통하여 신형식 교량에 대한 변위 및 최대 수직 수평가속도를 계측하여 동적응답 특성을 분석하였다. 이러한 실험결과를 바탕으로 수치해석을 실시하여 증속주행에 대한 거동을 예측하였다.
