Abstract

Abstract

To study the mechanical properties of steel truss support platform during the construction of the roof of large-scale silos, taking a silo project in Guangdong province as an example, the force condition of steel support platform was monitored during the whole concrete pouring process on the silo roof. The results showed that, because the lifting points were not at the same horizontal height, the maximum stable stress ratio of the main components of the platform was 0.25 during the lifting process. In the concrete pouring process of the inclined shell roof, the stable stress ratio of the main components was not more than 0.58, and the maximum vertical deflection of the support platform was 22 mm. In the process of concrete pouring of the top flat roof, the maximum stress of the support platform was less than 18 MPa because the concrete of inclined shell roof had hardened and could bear the most vertical load. The above indicated that the support platform had enough safety reserve and could be optimized. Finally, the silo roof construction process was simulated by using the ABAQUS software. On the whole, the simulated results agreed well with the measured results which indicated that the numerical method could be used to study the mechanical properties of steel truss support platform during the construction of the roof of large-scale silos.
