Abstract

WiththehelpofANSYS/LS-DYNAfiniteelementsoftware,thedirectionalblastingcollapseprocessofacertainhighframe- shearwallstructurewasnumericallysimulatedbyusingtheintegralmodelandcommonnodeseparatemodel. Andthenumericallysimulatedresultswerecompared withtheactualproject.Comparisonsshowthatthesimulatedresultsbyusingthecommonnodeseparatemodelareinbetteragreementwiththeactualproject. Inaddition,thenumericallysimulatedresultsdisplaythatthecollapsescopeofthestructurecanbereducedbyproperlyascendingtheblasting cutofthestructure.Finally,thestress-timecurvesofthesteelandconcreteelementsindicatethatthe commonnodeseparatereinforcedconcretemodelcancorrectlyreflectthemechanicalpropertydifferencesbetweensteelandconcrete.
