MAXIMUM RESPONSE MEMBER ANGLE MEASURING INSTRUMENT FOR ELEVATED BRIDGE POST

摘要

PROBLEM TO BE SOLVED: To provide a maximum response member angle measuring instrument for an elevated bridge post to directly measure the maximum response member angle of the bridge post by using inexpensive mechanical sensors of a power source-less system. SOLUTION: This maximum response member angle measuring instrument for an elevated bridge post is equipped with: two mechanical peak sensors 3A and 3B of a power source-less system disposed in an X direction and in a Y direction normal to the X direction, respectively, and mounted on an upper-layer beam 2 of the elevated bridge post 1 by means of a first tool 4; and an arm 6 provided with a rocking part 8 on the upper-layer beam 2, engaging with one end of each of the two peak sensors 3A and 3B of the power source-less system, and further extending downward to cause its lower end part to engage with a second tool 7 at a position excepting a plastic hinge zone of the bridge post 1.
