| Abstract | Observed local damages through either visual inspection or non-destructive testing may characterize the in situ properties of defects on structural elements but may not adequately address the global condition of the entire building. The effect of local damages on the performance of an entire building is studied. A framework correlating the local damages to the entire building is created by introducing defect severity scales and stiffness reduction modifiers. This study is carried out by first defining the types of defects that may have significant effects on the overall performance of the building. Next, defect severity scales and stiffness reduction modifiers are defined to represent the local damages. Then, damaged and undamaged finite element structural models of a mid-rise building are constructed. Finally, the performance of the building subjected to typical design wind loads and a severe earthquake ground motion is evaluated by comparing the lateral deflection at the roof top for damaged and undamaged models. This framework may assist in maintenance decision-making processes as it may help to prioritize which defects and structural elements should be repaired with a limited amount of available budget. |
