Study　on　the　construction　monitoring　was　used　to　focusing　on　the　Bridge　and　Tunnel.　The　construction　of　the　steel　structure　workshop　more　and　more　appeared　in　the　past　few　years,　proper　method　of　stress-strain　monitoring　of　the　key　component　while　construction　of　steel　structure　workshop,　become　particularly　important　factor　to　ensure　the　safety　of　construction　process.　Based　on　practical　example　of　Jinbei　automobile　factory　workshop,　the　paper　describes　the　stress-strain　monitoring　of　steel　beam　during　column　demolition.　Through　the　design　of　test　solution　and　the　analysis　of　test　data,　get　the　suitable　scheme　of　stress-strain　monitoring,　stress　and　strain　field　monitoring　of　the　basic　program,　meeting　the　monitoring　requirement　whether　steel　beam　is　safe　and　reliable　during　column　demolition,　and　could　provide　basis　and　support　for　similar　conditions　on-site　monitoring.　©　(2012)　Trans　Tech　Publications,　Switzerland.
