A landmark experimental program was conducted to advance the understanding of nonstructural system performance during earthquakes. The centerpiece of this effort involved shake table testing a full-scale five-story reinforced concrete building furnished with a broad variety of nonstructural components and systems (NCSs) including complete and operable egress, mechanical and electrical systems, facades, and architectural layouts. The building-NCS system was subjected to a suite of earthquake motions of increasing intensity, while base-isolated and then fixed at its base. In this paper, the major components of the test specimen, including the structure and its NCSs, the monitoring systems, and the seismic test protocol are described in detail. Important response and damage characteristics of the structure are also presented. A companion paper describes the damage observed for the various NCSs and correlates these observations with the structure's response.

A full-scale, 5-story building was designed and constructed on the NEES-UCSD shake table. The building is outfitted with a wide range of common nonstructural components and systems (NCSs). Amongst these are two large computer servers donated by industry, with one supported on a raised access floor and the other conventionally anchored to the floor slab. In this paper we present the scope of the broader test program, an overview of its building structural design and numerical modeling, and relevant to this session, pre-test numerical simulation of the access floor -computer rack system. Pending the test schedule, preliminary test results for the computer rack -access floor system may be presented at the conference.

“…Two tests have been reported in the literature, and the tests exhibited satisfactory hysteretic performance and drift capacity. Chang et al (2008) report the test results of two interior beam-column specimens whose beams incorporated ASTM A722 and A1035 beam longitudinal reinforcement. These test specimens are referred to as Specimen 3 and Specimen 4.…”

Use of high-strength reinforcement in earthquake-resistant concrete structures

to study and make recommendations concerning the utilization of high-strength steel reinforcing bars in concrete structures subjected to earthquake ground motion. This work grew out of the ATC-57 report, The Missing Piece: Improving Seismic Design and Construction Practices (ATC, 2003), which defines a roadmap for the NIST problem-focused research and development program in earthquake engineering. The ATC-57 report recommended that NIST examine new technologies that can improve construction productivity, such as high-strength reinforcement. The NEHRP Consultants Joint Venture is indebted to the leadership of Dominic J.
