- Abstract
- An evaluation of the safety-related seismic performance of existing low-rise building structures is described. The theory of structure reliability is reviewed and error and defect related failures for new constructions are assessed. Failures related to wearout and deterioration also are discussed. Estimation of structural reliability requires determination of the configuration, material, and type of construction. The behavior of an existing completed structure may not correspond to the mathematical model used prior to construction. For certain important structures, nondestructive tests are performed to collect selected load and response data. Techniques of system identification then are applied to obtain a more selective mathematical model for further analysis. An existing structure can be tested either periodically or immediately following an extreme event. Literature relating to new construction failure is reviewed. The need for a set of standard nondestructive testing and inspection techniques is discussed.
