The maximum weight of a steel roof structure of coal storage silos is 350 ton for the third-phase of Shenhua Huanghua Port. Altitude overall installation of the steel structures is difficult and critical. In the light of the large weight of the steel members,high lifting height,limitations on site, tight construction period,and safety, and other aspects of the instal-lation works,different installation technologies were compared and the stress on the steel structure when being integrally lifted was modeled and analyzed with MIDAS to determine the rational lifting points to ensure the overall stability of the steel struc-ture when being integrally lifted and installed. The paper introduces the technology and methods for lifting and installation of oversized steel structures for grouped storage silos,the successful application of which may provide a reference for similar pro-jects.
