Experimental study on five-story full size apartment house of reinforced concrete walled frames

Abstract

This report is concerned with the experiment of 5-story full size apartment house of reinforced concrete walled frames, conducted by Building Research Institute entrusted by Japan Housing Corporation. The purpose of this experiment is to examine the characteristics of this type of structure under the seismic loading and to improve its structural design.

The special feature of this specimen lies in, in a word, its economic design which is considered to be close to the structural and working criteria - the thickness and the length of the wall are 15cm and 12cm/m² over the story, respectively, which are less than the limitations given by the requirements of Architectural Institute of Japan.

Tests are divided into two parts. One is the horizontal static loading test carried out until the specimen collapsed, and the other is the dynamic test to investigate vibration properties in both elastic and plastic zones.

The outline and results of these tests are presented together with the analyses of the test results.
