Shaking Table Test of 6 Story Wall Frame Building To Investigate Collapse Process of RC Buildings

Abstract eng:
This paper describes the outline of experimental studies on collapse margin of reinforced concrete buildings. To reduce damages caused by large earthquakes, Special Project for Reducing Vulnerability for Urban Mega Earthquake Disasters has been conducted since 2012 by Ministry of Education, Culture, Sports, Science and Technology of Japan. In this special project, to quantify collapse margin of the buildings that are commonly seen in urban areas in Japan, shaking table test of a reinforced concrete building was conducted in E-Defense. The test specimen was a 1/3 scale model of a 6-story RC building designed according to the current Building Standard Law in Japan. The test specimen consisted of two moment-resisting frames in the longitudinal direction, and four frames with multi-story shear walls in the transverse direction, and the direction of main concern in this study was the latter. The two interior frames had shear walls and the others had nonstructural walls with openings from the second to the sixth stories. Recorded waves during the 1995 Hyogo-ken Nanbu Earthquake were used as the basic input motions. At the final shaking in the test, shear failure of walls at the first and second stories occurred, and the building specimen collapsed finally. As the test results wall failure mechanism and effect of the eccentricity were discussed. The maximum response capacity of the specimen in the transverse direction was precisely evaluated as the sum of shear strength of the walls and flexural strength of the columns.
