MAXIMUM RESPONSE MEMBER ANGLE MEASURING DEVICE FOR ELEVATED BRIDGE COLUMN AND METHOD OF EVALUATING DAMAGE LEVEL OF ELEVATED BRIDGE COLUMN

摘要

PROBLEM TO BE SOLVED: To provide a maximum response member angle measuring device for an elevated bridge column capable of directly measuring a maximum response member angle of the elevated bridge column using an inexpensive mechanical sensor of a system without power supply.;SOLUTION: In the maximum response member angle measuring device for the elevated bridge column, a plurality of measuring lines 5 to 8 having sequentially different attachment positions are stretched between an upper side surface 2 of the elevated bridge column 1 and a lower surface 4 of an upper layer beam 3. It is constituted so that the measuring lines 5 to 8 are sequentially broken in response to the magnitude of the maximum response member angle θ of the elevated bridge column 1. Thus, the maximum response member angle θ of the elevated bridge column 1 is measured.;COPYRIGHT: (C)2008,JPO&INPIT
