PSEUDO-DYNAMIC AND FORCED VIBRATION TESTS OF A FULL-SIZE TWO-STORY REINFORCED HIGH-PERFORMANCE CONCRETE BUILDING. IN: LARGE-SCALE STRUCTURAL TESTING

This paper describes a unique research program on the seismic behavior of a full-size high strength concrete (HSC) two-story frame structure. The originality of the research resides in the combination of systematic forced vibration tests and seismic pseudo-dynamic tests with increasing acceleration levels. This extensive test series will make it possible to study the seismic behavior of HSC structures and to accurately evaluate the level of damage imposed on the building. Horizontal and vertical acceleration frequency responses were obtained at several locations on both floors of the two story HPC building, which was submitted to harmonic loading. The responses were used to extract the structure's key dynamic properties, such as vibration frequencies and mode shapes, as well as modal damping ratios.
