Abstract
Thls study focused on the applicability of the fundamental period formula on
historic buildings with masonry shear walls based on the building code in
Taiwan. In order to verify the empirical formula proposed in the building code,
ambient vibration measurements were conducted on 28 historic buildings with
masonry shear walls to yield their hndamental periods, and then compared those
measured periods with periods estimated by the original formula. Two
disadvantages were shown in the original formula, poor correlation between
estimated and measured periods and unconservative estimation of the earthquake
force. To overcome these disadvantages, a new formula was estimated by only
taking into account the shear beha
