Integrated Architectural and Structural Design of a Multi-Storey Steel Educational Building: Code-Compliant Gravity, Wind, and Seismic Performance Assessment

This study presents the complete architectural and structural design of a multi-storey steel office and teaching building developed in accordance with current Chinese technical standards. The project integrates architectural planning, structural modeling, member design, seismic assessment, and foundation engineering into a unified design framework. The architectural concept was first established in Autodesk Revit, after which the structural model was transferred to Autodesk Robot Structural Analysis for detailed load application, automated load-combination generation, member verification, and connection design, following the requirements of GB50017-2017 and related national codes. The reinforced-concrete components including slabs, stair systems, and isolated spread footings were designed according to GB50010-2010 and foundation provisions of GB50007-2011. A modal seismic analysis was conducted based on the Chinese seismic code (GB50011-2010), with the structural system satisfying the requirement of achieving more than 90% cumulative mass participation in the principal directions. The analysis results show that the steel frame, supported by appropriately sized H-section columns and beams, delivers favorable stiffness and ductility under the design earthquake intensity of 7 degrees (0.10-0.15g).The final design satisfies strength, stability, and serviceability demands, and the structural components exhibit safe margins against lateral and gravity effects. The project demonstrates the efficiency of the integrated modeling-to-analysis workflow and highlights the advantages of structural steel for mid-rise educational buildings.
