New　Building　Beijing　Archive　is　a　steel　frame　structure.　There　are　some　local　roofs　of　truss　structure　in　second,　fourth　and　seventh　floor.　The　fourth　floor　as　shown　in　Figure　1　consists　of　two　lengthways　trusses　and　seven　transverse　trusses.　Several　trusses　were　assembled　into　a　whole　in　advance　and　lifted.　Because　of　the　discontinuity　in　geometries　and　stiffness　which　result　in　high　stress　concentrations　and　complicated　mechanical　properties,　three　dimensional　finite　element　analyses　of　global　truss　structure　is　modeled　by　the　present　work,　to　simulate　truss　lifting　construction　process　of　all　structure　stress　distribution,　the　size　of　the　vertical　displacement,　lifting　point　reaction　in　a　variety　of　situations　and　the　effect　for　beam-column　connection.　The　success　of　this　case　provided　useful　experience　and　engineering　practice　of　the　applied　technique　of　integral　lifting　with　asymmetric　lifting　points.
