Abstract:The new terminal architectural profile at Xishuangbanna airport looks like a dancing peafowl and ichnographic figure resembling the letter “T”. The roof of the terminal is an orthogonal grid structure supported by the column, made of the reinforced concrete filled steel tube member under the level of 7.8m and the steel tube on the other levels- The main structure underneath employs a reinforced concrete frame for the part of three floors. The different structural schemes for the new terminal are compared to obtain the economical and reasonable structural scheme. The different kinds of members are given different performance design objective, meeting the condition of economy, reasonability and security. The whole model is built to conduct the structural performance design and study the structural elastic and elastic-plastic performance, via the normal and fortification intensity seismic spectral analysis and the elasticplastic time-history ultimate seismic analysis, to provide the design support. As shown in the results, the objective of performance design is reasonable for this project, and the structure is ensured safely.
Keywords:performance design; elastic-plastic time history analysis; plastic hinge; seismic capability
