In seismic retrofit design, well-balanced placement of retrofit elements in a building is most essential to ensure sound seismic performance during earthquake. However, in case of retrofitting an RC building with steel framed braces, their unbalanced distribution is often considered a minor problem due to their stiffness lower than RC walls. To investigate the effects of unbalanced distribution of seismic elements on the torsional response of structures, shaking table tests are carried out. In this test, two 1/10 R/C frame specimens are studied: one specimen is retrofitted with RC wall (specimen RCW), and the other is retrofitted by steel brace (specimen SFB). The results show that the columns of specimen SFB are severely damaged than those of specimen RCW due to the bi-directional loading caused by torsional response.
