SEISMIC PERFORMANCE EVALUATION OF INDONESIAN TRADITIONAL WOODEN STRUCTURES DAMAGED BY 2006 CENTRAL JAVA EARTHQUAKE

This paper reports the results of the analysis for traditional wooden houses at Kotagede near Yogyakarta which damaged by 2006 Central Java Earthquake based on field survey, static loading test for mock test frames and evaluation of seismic motion intensity. Major findings are as follows: (1) In the field survey, structural and vibration characteristics are clarified. (2) In the experiment, horizontal resistance force is influenced by beam-to-column joint specifications. (3) Using proposed modeling method for the traditional frameworks, earthquake motion intensity at Kotagede is estimated at PGA=250cm/s2 based on the seismic performance evaluation of damaged houses.
