Abstract: This report is Part I of a three-part series prepared for a comprehensive evaluation of typical gravity load designed low-rise reinforced concrete frame buildings. Only the general non-seismic detailing provisions of ACI-318-89 were used for the design. The one-third scale three story model, one-bay by three-bay, of a typical office building was constructed to represent the critical interior bay of a prototype structure. A series of varying intensity simulated ground motion tests were performed on the one-third scale building model using scaled accelerograms on the shaking table to represent minor, moderate, and severe earthquakes. The dynamic characteristics of the model after each seismic event were identified from white noise shaking table tests. Analytical models were developed to predict and interpret the seismic response of the building model based on identified member properties from engineering approximations, component tests, and an experimental response fit. This report presents the design objectives, geometric dimensions, material strengths and initial dynamic properties of the model building, along with the simulated base motions, so that analytical models can be developed and used to predict the inelastic response of the model building during more severe earthquakes. The initial vibration tests and the response from a minor earthquake are presented to enable analytical structural modeling and verification of elastic response.
