Abstract:The design on three-centered cylindrical reticulated shell structure of four-105m-span dry-coal shed was introduced. It was found that the land use efficiency is increased significantly if the support of the reticulated shell is installed on the top of 24-10m high columns rather than on the ground. The data conversion program based on MSTCAD and MIDAS software was programmed to convert the data of single span reticulated shell calculation model from MSTCAD to MIDAS, and then the integral spatial calculation model of a four-span dry-coal shed was built by combining lower supporting concrete beams and columns. The comparison between MIDAS and MSTCAD calculation results demonstrates the feasibility and accuracy of the design method, and it also provides a new solution for design and calculation of the integral spatial structure of similar multi-span spatial reticulated shell structure engineering project.

Keywords:four-span dry-coal shed; three-centered cylindrical reticulated shell; block wind vibration coefficient; block shape coefficient
