RESEARCH ON DESIGN SCHEME AND OPTIMIZATION OF LARGE SPAN GRID STEEL STRUCTURE
Large span spatial steel structures have been widely used due to their beautiful appearance,flexible layout,and excellent seismic response capability.On this basis,there are still many construction difficulties in the ac-tual construction process of this type of engineering project.To this end,research should be combined with practical engineering needs to develop a construction plan that is more in line with safety science and construction efficiency based on factors such as structural characteristics,site conditions,schedule requirements,and lifting equipment,in order to effectively solve key problems in engineering construction.
