Development of Low-cost Seismic Performance Control Methods for Existing Wooden Houses Considering Reduction in Environment Load

本研究以促进现有传统木结构房屋地震安全性的提高、减少地震破坏为目标，考虑到传统居住文化的继承、各地区的环境负荷，和良好的住房存量形成。研究了房屋在遭受白蚁侵害、腐朽和大震后的剩余抗震性能评估技术。 B）考虑环境影响和成本效益性能，开发了抗震性能评估方法、抗震改造方法和修复方法。c）从环境影响的成本效益性能和减少效果的角度，开发了抗震改造方法和恢复方法的评估方法，并对几个调查地区的适用性进行了检查。

In this research, following researches and developments have been performed aiming at promotion of the improvement in seismic safety of the existing tradition timber-framed houses, and reduction of earthquake damage, considering succession of traditional living culture, environment load to each area, and good housing stock formation.a) The evaluation technology of the residual seismic performance of houses after the biodeterioration by termite attack and suffering decay and big earthquakes have been developed. b) Seismic performance evaluation methods, seismic retrofit methods and repairing methods have been developed considering the environmental impacts and cost-benefit performance c) Evaluation methods for seismic retrofit methods and the restoration methods from viewpoints of cost-benefit performance and reduction effect in environmental impacts have been developed, and the applicability was examined to the several investigated districts.
