“…Accordingly, the seismic evaluation method for the Japanese-style wooden buildings in Taiwan was established. In addition, the relationship between measured natural frequency and calculated base shear coefficient of the offices was investigated, as the latter represents a critical index of seismic capacity (Hayashi et al 2010;Saito et al 2016). The relationship was also compared to the empirical formula obtained for wooden houses in Japan.…”

In order to conserve or reuse historic buildings in Taiwan which are located in an earthquake-prone area, it is critical to ensure their seismic capacity. The historical Japanese-style wooden houses are those of concern in this study. Three historical offices of this kind which were damaged in the 2010 Kaohsiung earthquake were selected. First, ambient vibration measurements were taken to investigate their natural frequency and vibration mode. Performance-based assessment for wooden buildings in Japan was adopted and modified to evaluate the seismic capacity of the offices. By comparing the evaluation results and the damage observed in the earthquake, applicability of the method was verified. Accordingly, a seismic evaluation method for the Japanese-style wooden buildings in Taiwan was established. In addition, the relationship between measured natural frequency and calculated base shear coefficient was investigated and compared to the empirical formula for wooden houses in Japan.

In this paper, a previously proposed method for story stiffness estimation of steel residential house is extended to estimate story stiffness of wooden residential houses considering non‐structural walls based on the available design information, that is, story weights, wall type, wall length, and wall opening type. Microtremor measurement data of several newly constructed buildings are used to determine unknown model parameters of stiffness estimation function, which minimize the estimation error of eigen frequency. The proposed method can simultaneously estimate the standard stiffness of wall element common to the same specification and the effects of wall opening and wall shape. The validity of the proposed method is examined by using measured actual microtremor records and drawing information of wall types and wall lengths of 19 wooden residential houses.
