To preserve and inherit traditional wooden houses in Kyoto, Kyoto City conducts a program to provide seismic performance diagnosis and seismic retrofitting plans for those houses. This paper analyzes the seismic retrofit plans of 138 houses which were conducted by the Kyoto City program to understand what is proposed as seismic retrofitting of traditional wooden houses in Kyoto. We compare before and after seismic retrofitting in terms of their weight and base shear coefficients, and so on. We also analyze retrofit costs and cost-effectiveness in the seismic retrofitting plans.
