In order to investigate the structural behaviors of cast-in-place pile and ground beam subassemblages under lateral loading, some experiments using the subassemblage specimens were conducted. The results were summarized as follows. 1) In this study scope, the ultimate strength and failure mode of pile heads were little affected by that the pile caps were existing within the flexural tension region of ground beams, and all specimens had stable restoring force characteristics until large deformation. 2) The deformation of the subassemblages until pile reinforcement yielding could be estimated by the following values. a) The flexural and shear deformation of pile with the additional deformation due to relaxation of the pile reinforcement bond. b) The rotaion of the pile head due to the slip of the pile reinforcement anchorage in the pile cap concrete. c) The rotaion of the pile cap due to the deformation of ground beams.
