In Taiwan, brick walls are commonly constructed in historic buildings as the primary structural system. In addition to material degradation and ageing, the lack of out-of-plane flexural strength often makes brick walls extremely vulnerable during earthquake. In this study rehabilitation techniques for seismis retrofit of brick constructed buildings used in both foreign and loccal examples are introduced. For verification purpose, a case study on the structural retrofit plans of the Taipei Camphor Factor is presented to demonstrate the applicability of different rehabilitation schemes.
