Seismic Performance Improvement of A Torsional Irregular Concrete Shear Wall Building Using Toggle-Brace-Dampers

This paper describes a preliminary-assessment case study for seismic performance improvement of a stiffness and strength asymmetric concrete shear wall building using toggle-brace-dampers (TBD). The structure is a 16-story major regional phone switch building located in downtown Seattle. Its bottom 7-story including the basement was constructed in the mid 1950’s. […]
