Abstract

Based on the requirement of coal production capacity development in China, the design of dry coal sheds for storage is developing towards long spans and increased spatial capacity. The long-span double-layer cylindrical reticulated shell structure has emerged as the most widely adopted structural form for dry coal sheds. However, for structures with spans exceeding 120 m, the influence of the traveling wave effect on the structure cannot be disregarded. This paper focuses on a coal shed with a long-span double-layer cylindrical reticulated shell structure and utilizes the time history analysis method under multi-dimensional and multi-point excitation and Midas Gen software to study the influence factors of seismic traveling wave effect on the structure. The results reveal that: (1) A greater apparent seismic wave velocity contributes to a smaller impact of traveling wave effect on the long-span double-layer cylindrical reticulated shell structure; (2) Attention should be particularly focused on this impact when seismic waves propagate along the longitudinal span of the structure at a slow pace; (3) The traveling wave effect of near seismic waves on long-span double-layer cylindrical reticulated shell structure is greater than that of far seismic waves.
