Test research on seismic performance of story-adding frame structure

摘要

This paper conducts comparative experiments between reinforced concrete story-adding structure and the lightweight steel story-adding method. Quasi-static test research and a comparison and analysis of the experimental results are also performed for both reinforced concrete story-adding framework and light steel story-adding under the same working conditions. The results showed that although both structural frameworks do meet seismic construction requirements to some degree, the results of experimentation reflect distinct advantages and disadvantages for both methods. Results further indicate the applicability and relevant problems requiring attention for both story-adding methods.
