ABSTRACT
This paper describes examples of how experimental research can be used to facilitate Performance-based engineering. In addition, limitations and challenges in model idealization and loading are described. New opportunities to e some of these limitations are provided through the National Science Foundation (NSF) e E. Brown, Jr., Network for Earthquake Engineering Simulation (NEES) program and through the development of new test methods such as effective force testing (EFT) which will further facilitate the advancement of PBE.
INTRODUCTION
Experimental tests on structural subassemblages can lead to the advancement of performance-based engineering (PBE) concepts through development of new structural systems and retrofitting schemes, as well as, in the development of mathematical models of critical ponents. The numerical models can be incorporated in nonlinear numerical analyses to investigate the overall response plete structural systems incorporating similar details and subjected to a variety of ground motions.
Test structures typically represent key portions of structural systems, such as beam-column joints. In developing and testing subassemblages, simplifications are made which may result in the omission of elements (., slabs or soil-structure interaction) or ponents (., axial or bi-directional lateral loads) that can have a significant impact on the structural response. The National Science Foundation (NSF) e E. Brown, Jr., Network for Earthquake Engineering Simulation (NEES) may provide a means to e some of the experimental limitations by enabling tests on large-scale subassemblages, as well as integrated studies including effects of soil-structure interaction.
The development of new large-scale dynamic test methods, such as effective force testing, may be
