(1 Nanjing Military Area Architecture Design Institute, Nanjing 210029, China; 2 Nanjing Military Area Logistics Department Direct Office, Nanjing 210016, China)Abstract: Combining with design example of structure strengthening for adding floor in a project under construction, the main steps of structure strengthening design for adding floor were discussed in this paper. Using SATWE calculation software, the anti-seisnuc performance of whole structure of adding floor building was calculated. According to the maximum displacement, floor displacement, column axial compression ratio, column reinforcement parameters of adding floor building, the reinforcement of frame beam and column design method and construction technology were given by comparing with the original structure design.According to the pile static load test data and building subsidence observation data, the bearing capacity of foundation was checked by using the theory ofinteraction between pile and soil.
Keywords: adding floor of structure; structure member strengthening with externally bonded steel frame; structure member strengthening with R.C;interaction between pile and soil
