Abstract: Based on the design of a steel structure with a length of 70m and a span of 45m，this paper discusses the three aspects of architectural design，structure design and foundation design of coal storage shed in Shanxi xiang ning.The architectural design introduces the features of the coal storage shed，the retaining wall and the wall enclosure，the lighting setting and roof drainage，safe evacuation and fire prevention；through the calculation and analysis of single truss steel frame，the specification of steel frame column and steel roof frame is determined，by setting roof truss support，inter-column support and wind column，the coal shed has formed a spatial integral structure；the foundation design reduces the difficulty of construction by adopting the treatment plan of pile foundation and socket，and avoids the water culvert in the field.The design of this coal shed will provide reference for similar projects.
