Abstract: Structural system, design principle, and analysis results of Ningbo Lishe International Airport terminal 2 were introduced．Process of closely incorporating with architectural form and space demand to determine the steel roof system was demonstrated．The approximate global analysis method for segmental concrete structures with continuous roof was proposed．The elasto-plastic dynamic analysis to the monolithic structure by using explicit integral method was conducted．Progressive collapse analysis to the steel roof structure by using transient dynamic time history analysis was also conducted．The overall stability to the long column by using load-displacement whole process tracking techniques was analyzed and several key joints were illustrated．

Keywords： Ningbo Lishe International Airport； airport terminal; large span steel structure; progressive collapse analysis; overall stability; nodal analysis
