| Abstract: | Due to the difference of stress between the construction process and after the molding of large-span steel truss roof structures,there exists the force system transforming in the structure,so the safety in construction should be given attention to specially.According to this,the model of Guangzhou International Gymnasium's large-span steel truss roof structure is proposed here.At first,the construction process for the large-span roof structure of the gymnasium is simulated,and the observation system of the ... |
