Proposal and application of structural soundness monitoring system for the buckling‐restrained brace using steel mortar planks

A structural soundness monitoring system for building steel structures is effective a quick inspection just after large earthquakes. damage-controlled structure can be monitored effectively because damage strictly concentrated in energy-absorbed members, and that, this case, the physical quantity suitable displacements of those energy absorbed members. Buckling-restrained braces (also, BRB using mortar planks, BRBSM), one energy-absorption directly by sensor; it will possible to quickly evaluate extent make prompt decision on replacement. Focusing functionality system, evaluation method planks its corresponding are verified conducting cyclic loading test. It demonstrated that cumulative plastic strain estimated approximately adapted mid-rise building.
