The Outline of E-Defense Full-Scale Dynamic Test on a Ten-Story RC Building With Walls and Sliding Bases

Abstract eng:
The E-Defense, which is the world’s largest three-dimensional (3D) full-scale earthquake shaking table test facility, was built by the National Research Institute for Earth Science and Disaster Resilience (NIED) with the aim of shedding light on the failure mechanisms of full-scale structures during earthquakes and for verifying the effects of seismic retrofitting. Since its start of operations in April 2005, a wide variety of structures have been tested on this facility. In December 2015, NIED performed tests on a 10-story reinforced concrete building frame on the E-Defense in order to gain building engineering knowledge that will enable continued use of buildings after a major earthquake. In this experiment, data were obtained from a structure equipped with a base slip mechanism in order to study the efficacy of the base slip construction method. After the base slip construction test, the base of the same specimen was fixed in place to simulate conventional construction conditions and testing was conducted in order to compare fixed-in-place behavior with the base slip response behavior, determine the damage process of each member, and examine damage and response evaluation methods. This paper provides an overview of the base slip and fixed base tests while also presenting information on the specimen design and dimensions. In this building specimen, the sections were designed against the stresses acting in each member, whereas design loads were based on dead and live loads derived from the actual conditions during the test and the seismic load specified by the current standards.
