Abstract:
Full-scale dynamic tests provide valuable information on the characteristics of building structures that can be used to calibrate finite element models, to rate modeling techniques, to determine damage levels, and to evaluate design and detailing requirements for seismic loading. These tests usually provide the most complete information about the dynamic properties of a structure, I.e., mass, stiffness, and modal damping. In the paper, the dynamic behavior of a two-story reinforced high-performance concrete building is evaluated by repeated pseudo-dynamic tests, during which increasing seismic loads are applied and with resulting greater levels of permanent damage to the structure. In order to monitor the level of damage, a series of successive forced-vibration tests are also carried out at each step of the process and are used to track changes in the key dynamic properties of the building. The paper presents the design of the test structure, the series of forced vibration and pseudo-dynamic tests, the evaluation of the dynamic characteristics of te undamaged structure prior to and after pseudo-dynamic tests, and the evaluation of the damages to the building.
