- This paper discuss experimental research of connection between column and fondation. The column is made of column bataton filled by concrete and the foundation is made of cast in placed concrete. This topic is a part of research about �Solusi Rumah�, that was done in Structural Engineering Laboratory UGM. The column bataton material has dimension of 290x290x140 mm, its core is placed by the stell reinforcement and pour by the concrete. This research intent to study the behaviour of column subjected to axial load and lateral cyclic load as earthquake load. There are six specimens of connection between column and fondation which consist of three group. Each group has different shear reinforcements, the first group (KS-1A&KS-1B) has flexural and shear reinforcement of 4P12 and P8-200, group II (KS-2A&KS-2B) has flexural and shear reinforcement of 8P12 and P8- 95 and group III (KS-3A&KS-3B) has flexural and shear reinforcement of 8P12 and P8-60. All of specimens has dimension of 290 mm x 290 mm and 1800 mm height which fully fixed on fondation which has dimension of 1200 mm x1200 mm x 350 mm. Fondation was anchoraged to the rigid floor so that can be assumed fully fixed behavior. The speciment is placed between two leg of the loading frame, subjected to 126.3 kN of axial and lateral cyclic load at 1500 mm of height from upper suface of fondation. Test results show that specimen I (KS-1A&KS-1B) has average lateral load capacity of 21.5 kN, meanwhile on specimen II (KS-2A&KS-2B) and III (KS3A& KS-3B) occured increasing lateral capacity load up to 36.62% and 41.16% respectively to specimen I result. Ductility factor of specimen I is 9,46, meanwhile on specimen II and III increases up to 4.42% and 9.79% respectively to specimen I result. Stiffness of specimen I is 3.74 kN/mm, meanwhile increasing of specimen II and III to speciment I is 15.84% and 31.35% respectively. Drift ratio of maximum load is 1.09% meanwhile increasing of specimen II and III to speciment I is 35.65% and 36.22% respectively. Based on ACI T1.1-01, semi precast bataton column system can be applied for moderate momen resisting frame system with maximum value of R (modification respon factor) is 6. Failure criteria of all specimens are flexural failure.
