Abstract：
12.9 Building of Tongji University is an excellent historical relic building in Shanghai. To give better protection to the building, many inspections and tests are carried out, such as repetition measurement of building structure, detection of building damage, structural durability inspection, strength inspection of main materials and measurement of building gradient and differential settlement, etc. Safety and seismic resistance of building structure are analyzed to find out structural defects and propose reasonable reinforcement measures.
