本文介绍36m跨锯齿形锥壳屋盖厂房的动力实测和有限元方法计算其地震效应的分析结果。实测中采用了激振、冲击和脉动等方法,获得了该结构的自振频率、振型和阻尼。用有限元方法和程序进行了大量分析计算,探求到其动力特性和地震效应的特点。实测和计算均表明:计算的自振频率和振型与实测值符合;地震效应以垂直振型为主;一般应取前10个振型进行振型组合。试验研究结果表明该结构具有良好的抗震性能,在8度地震区使用是安全的。这一研究为推广和改进这类结构提供了实践和依据, This paper introduces the dynamic analysis and finite element method of the 36m-span zigzag conical shell roof building and calculates the seismic effect analysis results. The vibration, shock and pulsation were used in the actual measurement, and the natural frequency, vibration mode and damping of the structure were obtained. A large number of analytical calculations were performed using finite element methods and procedures, and the characteristics of its dynamic characteristics and seismic effects were explored. Both the measured and calculated results show that the calculated natural frequency and mode shape are consistent with the measured values; the seismic effect is dominated by the vertical mode; generally, the first 10 modes should be used for mode combination. The experimental results show that the structure has good seismic performance and is safe to use in an 8 degree seismic zone. This research provides practical and evidence for the promotion and improvement of such structures.
