Abstract
Semi-precast column consists of the combination of cast-in-place concrete and segmental precast concrete. In semi-precast concrete column, difference in compressive strength exists between the cast-inplace and precast concrete. This aim of this research is to investigate the behaviour of column-fondation joint of semi-precast concrete column under axial and lateral cyclic loading. The behaviour of column-fondation joint of semi-precast concrete column has been evaluated by using ACI T1.1.2001. The result show that the column complies with acceptance criteria of ACI T1.1-01 at point c. Thereby column bataton can be used only at the moderate moment resisting frame system (SRPMM) of precast concrete structure, with maximum value of R (modifications response factor) is 6 (ACI T1.1-01).
