This paper proposes a new method to analyze wind-induced response in frequency domain for long-span spatial structures. This method is based on proper orthogonal decomposition (POD) and pseudo-excitation methods, which could significantly reduce computational cost. Based on the POD-pseudo-excitation method and the wind pressure coefficient obtained from a wind tunnel test, ANSYS general purpose software package was developed for the analysis of wind-induced response of YUJIAPU Railway Station Building, which is designed in the form of a conch-shaped single-layer lattice shell. The wind vibration coefficient in wind direction of 0° was obtained. Results obtained by frequency- and time-domain methods were compared. The results were consistent with each other, establishing the foundation for further application of these methods in wind-induced analysis. The relationship between wind-induced response and the frequency of wind load was also determined. This paper provides effective guidance on equivalent wind load.
