China Phase Longwang Tender

Recently the 53.4-meter long-span steel truss of the RD headquarter building of the first-phase project of the Longwang Bay RD Base of the Zhanjiang Bay Laboratory in Zhanjiang City which was constructed by CSCEC was successfully hoisted.The upper structure of the RD building is supported by a 53.4-meter long-span steel truss and its long-span structure is like a bridge on the sea.The upper part of the truss holds a 6-storey steel structure with a self-weight load of more than 10000 tons. With a high load and many rigid structures the project applies complex construction technology in its building.In order to complete the tasks safely and efficiently the project team adopted a 3D modeling steel structure collision analysis selected the scheme through finite element software construction check and set up 129 stress and 15 sets of deformation monitoring points. With a third-party real-time online monitoring the project ensured structural and construction safety during the whole process.
