Based　on　test　results　of　two　full-scale　reinforced　concrete　beam-column　joints,　carrying　capacities　of　core　areas　of　the　joints　were　calculated　and　modified　based　on　the　strut-and-tie　model.　The　results　indicate　that　the　capacities　calculated　with　h-D-regions　is　smaller　than　those　with　h/2-D-regions,　and　the　calculated　results　with　h/2-D-regions　agree　better　with　the　test　results.
