| Abstract: | A full-size steel space truss model was tested in this experimental investigation.Damage of various structural members and support settlement were simulated.Relatively mature techniques including static response test and low order modal test were utilized as measuring method.Some useful variation laws of structural property and response due to damage were find out.The investigation results can provide references for health monitoring and damage identification of long span structures. |
