Development of a Quasi-Static Loading Protocol for Displacement-Sensitive Nonstructural Building Components

Abstract eng:
Findings from both analytical and experimental research projects as well as observations of damage occurred by previous earthquakes indicate that the loading history has a significant influence on the induced damage in nonstructural components of buildings in seismic events. For the purpose of either designing new buildings or performance evaluation of existing ones, it is necessary to use appropriate loading protocols in experimental tests for developing accurate component damage fragility functions. The crucial concern here is to suggest loading protocols which could be representative of the actual demand imposed by a seismic event. Current quasi-static cyclic loading protocols have been mainly developed in part by statistical evaluation of seismic response data and in part by judgment. Hence, the need for statistically well-defined standardized protocols that outline the test procedure is clear. The main goal of the present research is to develop quasi-static loading protocols for displacement-sensitive nonstructural components. Developed quasi-static loading protocols help to predict the probable behavior of displacement-sensitive nonstructural components during an earthquake more accurately by considering the loading history characteristics of the seismic event, and as a result, optimize the cyclic testing results for both design procedures and loss estimation purposes.
