Abstract：Based on an overseas hydropower station project,the design and application of light steel structures in the powerhouse roof system were detailed.A SAP2000 three-dimensional finite element model was established,where roof panel stiffness was verified using virtual surface element simulation,and structural nodes were simplified into rigid and hinged nodes based on classification.According to European standards,the overall stability,component strength,and deformation of the roof were verified under applied loads and working conditions,providing support for design optimization.This study offers a useful approach for the design and structural verification of overseas hydropower powerhouse roofs,serving as a reference for relevant engineering personnel.
