Performance of a deteriorated existing reinforced concrete (RC) building, which had been on service since 1970, was investigated. The building that was designed based on the old AIJ Standard for Structural Calculation of Reinforced Concrete Structures (AIJ,1962) was planed to be deconstructed and removed. Since authors had a chance to carry field experiments on the building before deconstruction, field-loading test on the portal frame was performed to evaluate its structural performance. Prior to the loading test, concrete core specimens were taken and used for compression test and also measurement of carbonation. Then, ultimate behavior as well as elastic behavior of the portal frame was examined through the horizontal loading tests. In this paper, results of the field test and measurement are reported and performance of the building so investigated is discussed.
