civil air defense engineering;  Peacetime and wartime function conversion;  Post plus column

Civil air defense engineering peacetime and wartime function conversion is an important guiding ideology of civil air defense engineering construction and development, civil air defense engineering main structure reinforcement transformation must meet the three indicators of reliability, rapid and economical, post-column technology is the main structure of civil air defense engineering to improve the structural resistance level of more practical method, wooden column is an easy to process and install and economically feasible post-column form. Using the beamless plate structure, the stress-strain relationship and possible failure characteristics of the concrete and steel bars in the concrete and components on the slabs, walls and columns were analyzed by the step-by-step loading test of the water bladder. The test results show that the wooden column can be used for the reinforcement and transformation of the main structure of civil air defense engineering.
