Seismic Performance Assessment of Expansion Joints through Shaking Table Test: Part I Test Plans and Results

摘要

The main findings are summarized as follows.rn1) The relative displacement at the moment of damage forrneach EXPJ was identified by using strain gauges attachedrnnear the location of damage and collision.rn2) Damage states were identified for the tested EXPJs. ThernA-rank EXPJ had damage state 1 after the design motionrnrange of 17.5 cm. The B-rank EXPJ had damage state 1rnbefore the design motion range and failure state rightrnafter the design motion range.
