The Botany Stadium Analysis Of Long-span Space Steel Structure

Recent years, with the rapid development of economy, many kings of large span space structures are being adopted to stadiums widespread in domestic constructions.The public focus on the security of these complicated and alternative structures during the construction processes and installation technology, because in order to ensure the construction safety, economy, smoothly, the construction methods are various and intricate, and various uncertainties may exist in the construction processes.Meanwhile, their performance in these processes may not satisfy the demand of designs. We should determine the reasonable order during the construction process to make sure the engineering construction security and economical. It is necessary to simulate the whole construction process of the large span steel structure to make out the mechanics property of structure and study the relevant problems after this process.In this paper, the current development of China’s large-span steel structure construction technology background of recent developments in the status quo of existing research base steel span space at home and abroad, for space to analyze the mechanics of steel construction phase, combined with plant Qingdao International Horticultural Exposition Hall examples of large-span structures further research installation technology.The first analysis of the situation of the Qing Dao EXPO botany stadium. Put forward the concrete measures of steel structure installation process. Secondly, in the calculation of the load on the install and uninstall simulation analysis, calculation, simulation analysis of latticed truss hoisting and lifting lock selection checking simulation analysis. At the end of the steel structure welding,including welding method, welding preparation, welding sequence, welding seam corrosion and welding deformation and stress control analysis.The main conclusions of this paper are : through the analysis of large span spatial steel structure installation technology, pay attention to the installation key technology,to avoid the occurrence of accidents, to further improve the level of construction technology.
