BRIDGE STRUCTURE HAVING SELF-WEIGHT SUPPORT MECHANISM
PROBLEM TO BE SOLVED: To provide a bridge structure having a self-weight support mechanism capable of, even when an unexpected damage is generated on a vertical member such as bridge footing or pillar due to occurrence of an unexpected earthquake etc., maintaining the performance to support a superstructure to reliably prevent a state where the superstructure falls from the vertical member, namely, bridge fall.SOLUTION: The bridge structure such as a bridge or a viaduct includes a girder 1 as a superstructure, and existing pillars 2 as vertical members supporting the girder 1. Self-weight support pillars 3 are installed together with the existing pillars 2 as a self-weight support mechanism which has a function to support the girder 1 when the existing pillars 2 get a damage.SELECTED DRAWING: Figure 1
【課題】想定外の地震が発生することにより、想定以上の損傷が橋脚や柱等の鉛直方向部材に生じても、上部工を支持する性能を保持して、上部工が鉛直方向部材から落下する状態、すなわち、落橋を確実に回避することができる、自重支持機構を有する橋構造物を提供する。【解決手段】上部工としての桁１と、桁１を支持する鉛直方向部材としての従来柱２とを備えた、橋梁や高架橋等の橋構造物において、従来柱２が損傷した場合、桁１を支持する機能を有する自重支持機構としての自重支持柱３が従来柱２と併設されている。【選択図】図１
