Examination of Destruction of Non-structural Members and Fall of Utensils by Long-period Earthquake Ground Motion in High-rise Building
(Mar. 2007) （
Test Number: E200608 ）
A full-scale test structure which was partially extracted from a high-rise building was shaken to reproduce the floor response and story drift. The experiment was conducted in order to clarify those phenomena which may occur in and outside of high-rise buildings under a long-period ground motion. Damage of nonstructural components including exterior wall and ceiling as well as dangerous behavior including overturning and scattering of fixtures and fittings were observed in the test structure. Adopted earthquakes were Nankai earthquake expected in near future and the 1995 Southern Hyogo Prefecture Earthquake.

Japan-US Collaborative Research on Innovative Seismic Isolation Solution
(Aug. 2011) （
Test Number: E201102 ）
In collaboration with the University of Nevada, Reno in USA and National Research Institute for Earth Science and Disaster Resilience, the shake table experiments on a base-isolated building were conducted to evaluate the effectiveness of seismic isolation technology. Specimen was a five-story steel building and isolation devices were installed at the base of the specimen. In the experiment, two different types of isolation system were used; 1) nine triple-pendulum bearings and 2) combination of five lead-rubber bearings and four cross linear sliders. Base-fixed specimen also excited to compare response of the specimen and behavior of furniture installed in the specimen. The record observed at K-NET Iwanuma station during the 2011 Off the Pacific coast of Tohoku earthquake was imposed. Duration of this record is about three minutes and it affects various structures because it contains long-period components, which resonate with base-isolated buildings, and short-period components, which affects low to middle height base-fixed buildings.

Research and Development of the Measures for Damage Mitigation caused by Long-period Ground Motion
(Oct. 2011) （
Test Number: E201103 ）
In this study, two cases were used for the experiment: a high-rise building model and a low-rise building model. The high-rise building model was based on a 30-story building with a height of 120 meters. The test specimen consisted of the lowest steel frame, which was designed to produce the same shaking as a 6-story high-rise building, and the two upper steel frames, which were designed to produce the same shaking as a 27-story and 28-story high-rise building. The remaining middle part was replaced with a heavy concrete slab and laminated rubber. In the low-rise building model, the middle part was fixed with steel plates to prevent the laminated rubber from working. The test specimen had the widest floor area of any of the previous experiments, and included office and residential spaces. The office space had a suspended ceiling, incorporating both the line ceiling that has been used in many buildings to date, and the grid ceiling, which is advantageous from the perspective of earthquake resistance. Furthermore, the ceiling also incorporated general equipment such as air conditioning units, as well as firefighting equipment such as sprinklers, fire alarms and emergency lighting, reproducing the same equipment functions as in a real building.

Experiment on Non-Structural Components Installed in Large-Spanned Building Structures
(Jan. & Feb. 2014) （
Test Number: E201306 ）
In a project to experimental research large-scale buildings in school facilities, shaking tests were conducted using a test specimen that simulated a gymnasium with the world's largest area of ceiling test specimen, and the damage caused by the falling of suspended ceilings in many facilities during the 2011 Tohoku Pacific Offshore Earthquake was reproduced. Through this experiment, it was possible to capture on film for the first time in the world the process of the metal fittings of suspended ceilings attached to actual buildings coming loose and the ceiling falling. In addition, the effectiveness of the fail-safe function, which prevents human injury by catching the falling ceiling and stopping it from reaching the floor, was also confirmed. Experiments were also conducted on ceilings (earthquake-resistant ceilings) that complied with the technical standards enacted in April 2014, and it was confirmed that they were able to withstand the shaking of the 2011 Tohoku Earthquake, which was more than double that assumed in the design.

E-Defense Experiment to verify the Function of 3-story Wooden Building including Underground Piping Equipment
(Jan. & Feb. 2019) （
Test Number: E201806 ）
In the “Tokyo Metropolitan Resilience Project ” - a project subsidized by the Ministry of Education, Culture, Sports, Science and Technology - E-Defense is being used to collect and maintain data on the maintenance of building functions, including interior and exterior materials, furniture, fixtures, and piping, and on the seismic margin of buildings until they collapse, with the aim of quickly restoring urban functions in the event of a major earthquake, identifying damage, and carrying out repairs.
In this experiment, two three-story wooden houses were tested on a shake table: one with an earthquake-resistant structure that had been reinforced to improve its earthquake resistance, and the other with a seismic isolation structure, which is known to be effective for earthquake countermeasures, from the perspective of ensuring the living functions of residential buildings in densely populated residential areas. The size of the test specimen was 4.5 m x 10 m in plan and approximately 10 m in height. For the seismic-resistant structure, a large-scale soil container with internal dimensions of 7 m x 13 m and a height of 2.5 m was constructed, and a 1.3 m deep soil layer was built inside the container to faithfully reproduce the building conditions from the solid foundation to be constructed on top of the soil layer. Valuable data was collected by inputting observation waves from the 1995 Southern Hyogo Prefecture Earthquake, etc.

Holistic Seismic Assessment of Critical Buildings with Due Consideration of Non-Structural Component and Equipment
(Dec. 2020) （
Test Number: E202003 ）
In the “Tokyo Metropolitan Resilience Project ” - a project subsidized by the Ministry of Education, Culture, Sports, Science and Technology - E-Defense is being used to collect and maintain data on the maintenance of building functions, including interior and exterior materials, furniture, fixtures, and piping, and on the seismic margin of buildings until they collapse, with the aim of quickly restoring urban functions in the event of a major earthquake, identifying damage, and carrying out repairs.
In this research project, with the aim of developing a system to support safe and efficient decision-making by hospital administrators in the aftermath of a disaster, a large-scale shaking table experiment was conducted on hospital buildings equipped with high-performance facilities. The experiment was designed to propose a method for quantitatively assessing the degree of functional loss immediately after an earthquake in regional core hospitals and other facilities expected to maintain continuous operations during disasters, thereby avoiding unnecessary confusion. Two test structures, a four-story earthquake-resistant building and a three-story earthquake-isolated building, are connected by a bridge corridor. Medical equipment was installed inside the test structures to reproduce the conditions of an actual medical facility. Based on the results of the experiment, this study proposes a quantitative evaluation method for determining the building collapse margin, identifying factors that cause a decline in hospital functions, evaluating the performance of individual high-performance facilities, and assessing the loss of facility functions.

E-Defense Experiment for Earthquake Damage Mitigation and Damage Assessment for Indoor Spaces and Functions
(Dec. 2021 & Jan. 2022) （
Test Number: E202104 ）
This research aims to collect data on seismic damage to nonstructural members, indoor facilities, furniture, fixtures, etc., and to propose guidelines for damage verification methods, damage prevention methods, and seismic damage sensing methods. Specifically, a large shaking table test specimen that can reproduce damage caused by earthquake motion to various nonstructural members, indoor facilities, furniture, fixtures, etc. (a test unit that can be used repeatedly by replacing nonstructural members, indoor facilities, furniture, fixtures, etc. installed inside it for each test while the main structural members remain undamaged) was prepared and tested for various types of earthquake motion. The data on damage to each nonstructural member under various earthquake ground motions would be collected. Furthermore, these data sets have been developed and examined with the aim of constructing a damage monitoring method.
In order to achieve the objectives of this research, large-scale shaking table experiments were conducted to evaluate damage to indoor spaces under various seismic motions and to obtain data related to post-earthquake business continuity and so on.

Shake-table Test for Assessing Dynamic Characteristics of Building Structures using a 10-story Steel Office Building
(Feb. 2023) （
Test Number: E202204 ）
To save lives and keep society and the economy going in the event of a big earthquake like the one expected in the Nankai Trough in the near future, it is essential to get ready now and have a plan for after the earthquake so decisions can be made quickly. The National Research Institute for Earth Science and Disaster Resilience is developing a “dynamic characteristic evaluation method” that assesses the dynamic characteristics of buildings, such as their shaking period and ease of settling, based on their shaking patterns. To this end, a joint research project with a private company is underway to develop exterior materials (LED light alert system) that incorporate sensors to measure building shaking and LED lights that instantly display the measurement and evaluation results. Here, shake table tests were conducted to verify and validate the dynamic characteristic evaluation method and LED light alert system. The test specimen was a full-scale 10-story office building with a floor area of 12.0 m × 8.0 m, 10 stories, a height of 26.9 m, and a weight of approximately 700 tons. In the experiments, the test specimen was subjected to repeated small earthquakes with seismic intensities of 2 to 4 and large earthquakes with seismic intensities exceeding 5 to capture changes in dynamic characteristics. An LED light alert system was also installed on the test specimen to demonstrate the immediate light emission display of deformations. The results of the experiments demonstrated that the developed dynamic characteristic evaluation method could capture changes in dynamic characteristics, and that the LED light alert system could accurately measure building deformation and display it in real time using LED lights. Additionally, through a framework for joint research and the provision of surplus space, various interior materials, furniture, fixtures, and equipment were installed inside the building, enabling the acquisition of valuable data on the shaking, movement, and damage caused by earthquakes.
