Flexural behavior of double straight notch joint beam column exterior due to lateral cyclic load

Abstract

This study aims to determine and analyze the flexural behavior of the double straight notch joint beam column exterior due to lateral cyclic load. There are 3 (three) scale test specimens, BK monolith, SBK type 1 and SBK type 2. The joint model on the beam is a double straight notch and uses the method of mechanical connection and grouting. Loading with alternating lateral loads assumed as cyclic loads. Testing and analysis using the Displacement Control Method with the standards of the European Convention for Constructional Steelwork (ECCS) 1986. The results showed that the stability of SBK type 1 and type 2 specimens in terms of the characteristics of the hysteresis loop curve had a curve similar to BK monolith. The greatest displacement in compressive conditions occurs in SBK type 2 while drag conditions occur on monolithic BK. From the results of the study, it is also known that lateral loads are directly proportional to displacement, where the higher the lateral load is borne the greater the displacement experienced and vice versa. The displacement ductility that occurs is the partial ductility in type 1 SBK = 0.971 monolithic BK while SBK type 2 = 1.047 monolithic BK. Based on the results of studies of some of these behaviors, type 2 SBK has more advantages than type 1 SBK so that the results of SBK type 2 analysis can then be used as validation of monolithic BK.
