Abstract: The stacker structure of a coal storage yard located in Handan city was reformed. Problems exciting in structure were analyzed. The overall design scheme of structure reconstruction was determined. The scheme was subdivided, including connection construction, bearing design, joint treatment, load selection, load combinations and so on. STCAD truss analysis and design software was applied to analyze the structure. Results showed that the reformed structure has less steel dosage, better safety and economy, and meets the requirements. It can provide references for similar stacker reconstruction design.

Key words: stacker structure, pipe truss, reconstruction design, overall scheme, bearing connection
