Abstract: Several destructive earthquakes have occurred in Indonesia in recent years. The 2009 West Sumatra, Indonesia earthquake attacked Padang, and damaged a large number of reinforced concrete (R/C) buildings. The first author of this paper had conducted a post-earthquake field investigation in Padang, as a member of reconnaissance team organized by Architectural Institute of Japan (AIJ). As a result, it was found that one of typical damage to R/C buildings was beam-column joint failure. This damage was caused by poor structural details at joints nevertheless appropriate details were provided in the Indonesian design provisions.
This study focuses on the structural performance of a typical R/C exterior beam-column joint observed in an earthquake-damaged building in Padang. Two three-fourths scale exterior beam-column joint specimens were prepared and their performance was evaluated under cyclic loading. The test results showed that joint failure occurred prior to beam/column yielding, which means that the actual seismic performance of this kind of structure was less than the design assumption in which joint failure had not been considered.
