Research and Application Status of Seismic Analysis Techniques for Large-Span Spatial Structures

The dynamic properties of large-span spatial structures are much more complicated, making it crucial to develop and improve the techniques for seismic analysis of such structures from the perspective of performance-based seismic design. The research and application status of various analysis methods, including the mode superposition response spectrum method, the dynamic time-history analysis method, the incremental dynamic analysis method, the static push-over method, as well as the random vibration analysis method were summarized on the basis of the dynamic properties of large-span spatial structures. Some key issues that were pointed out during the research were also addressed in conclusion part.
