In general, health monitoring structures to ensure the security and integrity is very important. Afactor that puts the security and integrity of his work, began the process of creating the damagein structures. All the different methods fail to detect the domain name structural healthmonitoring or the SHM examined, and generally they can be divided into three categoriesmodal testing methods, techniques and new methods of divided vibration. Identify damagegenerally takes place in 4 main levels studied the levels are as follows: 1) the presence orabsence of failure, 2) positioning failure, 3) determine the extent of damage, 4) anticipated lifeof the structure. In this study, the detection of damage to the horizontal truss arched structures isstudied. In this study, using the software matlab, sap2000 horizontal truss arch bridge elementsjoined by model and for a specific type of failure (corrosion) by analyzing the sensor outputaccelerometer (acceleration) using Wavelet Energy severe crash site accuratelydiagnosed.ensuring structural safety.
