변형기여분에 따른 프리캐스트 보-기둥 접합부의 분류방안

초록

This study suggested an integrated classification method for generalized characteristics of PC beam-columnconnection according to connection details. Quantifying the failure mode of PC-beam column connection and characteristics ofcorresponding details, this study suggested to use deformation contribution of each element of beam-column assemblage. Accordingto the expected failure mode of beam-column connection assemblage, PC beam-column connection can be classified into ‘equivalentmonolithic system’ and ‘jointed system’. In this study, four test specimens were tested for verification of detailed classificationmethod of PC beam-column connections. Test was carried out with typical beam-column connection test method. Load was appliedat the top of test specimen and end of beams were restrained by hinge. In order to verify the deformation contribution of each testspecimen, 34-LVDTs were mounted on test specimen. According to test results, deformation contribution of each test specimen havedifferent characteristics. Deformation characteristics of joint and other components which are quantified by test results, equivalentmonolithic system can be classified into two categories. Strong connection have extremely small deformation contribution of jointand much larger deformation contribution was shown in flexural behavior of beam. The other type of beam-column connection isductile connection which allows the larger deformation in joint area compared with strong connection.
