Abstract:The effect of non-uniform seismic excitation should be considered in structural design of terminal building of Qingdao Jiaodong International Airport owing to its maximum length of 1 090m. The analysis of main hall indicates that the wave-passage effect of the axial force of roof truss member is relatively minor, while the maximum effect and distribution is found in the first storey columns and decrease with storey going up. The forces of most columns under non-uniform excitation are less than that under uniform excitation, and the wave-passage effect coefficient of over-load columns is concentrated between 1-0~1-25. Major effect is found in the columns near the edge, structural gap, large openings, and areas with diminishing plane width. These columns should be designed with larger capacity and ductility.
Keywords:Qingdao Jiaodong International Airport; non-uniform seismic excitation; terminal building; frame structure; wave-passage effect
