BRIDGE TRAFFICABILITY DETERMINATION SYSTEM
PROBLEM TO BE SOLVED: To provide a bridge trafficability determination system which: reduces time required for inspecting a bridge; can determine trafficability of the bridge by inexpensively and accurately comprehending response displacement which cannot be visually observed; and enables an inspection result to be known without being affected by congestion in a communication line.SOLUTION: In a bridge trafficability determination system, a bridge girder side measurement node and a structure side measurement node respectively installed on a bridge girder and a structure adjacent to an edge section of the bridge girder are connected to a bridge monitoring server device which determines trafficability of a bridge in a manner that allows mutual communication to be performed through a communication network. Integral value calculation means mounted on the server integrates acceleration values due to respective oscillation of the bridge girder side measurement node and the structure side measurement node twice. A SINC filter removes low frequency components of the acceleration values from integrated values. Relative displacement calculation means calculates a relative displacement of each measurement node. Determination means determines the trafficability of the bridge by comparing the relative displacement with a predetermined relative displacement threshold.SELECTED DRAWING: Figure 1
【課題】橋梁の点検調査に要する時間を短縮し、目視点検では把握できない橋梁の応答変位について把握する安価で精度の高い橋梁通行可否判定を可能とし、通信回線の混雑に影響されずに、橋梁の点検結果を把握する橋梁通行可否判定システムを提供する。【解決手段】橋桁と、橋桁の端部に隣接している構造物とに、それぞれ設置されている橋桁側計測ノード及び構造物側計測ノードと、橋梁への通行可否を判定する橋梁監視サーバ装置とを通信ネットワークを介して相互に通信可能に接続し、サーバ装置が備える積分値算出手段が、橋桁側計測ノードと構造物側計測ノードそれぞれの振動による加速度値を２回積分し、ＳＩＮＣフィルタが積分値から加速度値の低周波数成分を除去し、相対変位量算出手段が各計測ノードの相対変位量を算出し、判定手段が相対変位量と予め定められている相対変位量の閾値とを比較して、橋梁への通行可否を判定する橋梁通行可否判定システム。【選択図】図１
