This research was carried at first as Grant-in-Aid for International Scientific Research (University-to University Cooperative Research) and was preformed on the interchange agreement between Tianjin University and Kyushu Sangyo University and we obtained the following result.1. Investigation : In China, we investigated the buildings and the factories that had deteriorated and need repairs. In Japan, we visited the Hyogo prefectural office, the Fukuoka prefectural office and the Tokyo metropolitan office, and investigated uses and seismic repair methods of buildings that we repaired.2. I introduce seismic repair techniques in Japan by lectures and papers.3. Experimental studies : In China, physical properties of continuous carbon fibers made in China were compared with the one made in Japan and experiments to investigate the effect of strengthening were carried out in the case that the continuous carbon fiber made in China were used for bending reinforcement of RC beams and columns and for shear reinforcement of columns.In Japan, we carried out the experiments of several anchoring methods of continuous carbon fibers. Then we devised the jointing method between RC frames and increasing RC walls or the steel braces with frames (that were most widely used) by means of thin steel plate and epoxy adhesive agent instead of the post installed anchors and carried out the experiments to promote the gluing strength and the ductility of the jointing part and found that this method was practical and valuable.4. Technology interchange : We invited co-research worker to Japan twice and inspected the buildings under repair construction and experimental facilities.I visited to China twice too, and inspected the deteriorated factories then gave lectures about seismic repair and measures for concrete cracks of buildings.

本研究首先以国际科研资助（校际合作研究）的形式进行，并在天津大学与九州工业大学的交流协议基础上进行，得到了以下结果：调查：在中国，我们调查了已经老化需要维修的建筑和工厂。在日本，我们访问了兵库县办公室、福冈县办公室和东京都办公室，并调查了我们修复的建筑物的用途和地震修复方法。通过讲座和论文介绍日本地震修复技术。试验研究：在国内，将中国产连续碳纤维与日本产连续碳纤维的物理性能进行了对比，并以中国产连续碳纤维用于钢筋混凝土梁、柱的抗弯加固和柱的抗剪加固为例，进行了加固效果的试验研究。在日本，我们进行了几种连续碳纤维锚固方法的实验。在此基础上，设计了用薄钢板和环氧胶粘剂代替柱锚的钢筋混凝土框架与增加钢筋混凝土墙体或钢撑与框架（应用最广泛）的连接方法，并进行了试验，提高了连接部分的粘接强度和延性，证明了该方法的实用性和应用价值。技术交流：两次邀请合作研究人员赴日考察在建建筑和实验设施。我也去过中国两次，参观了破旧的工厂，并就地震修复和建筑物混凝土裂缝的措施进行了讲座。
