The purpose of this paper is to evaluate the moment resistance of glulam post-to-baseconnections by applying quasi-static cyclic loads. The connectors consisted of inserted platesand drifted pins according to the load direction. The connection types employed in this studywere total three including two unidirectional types (H, V) and the multi-directional type (M). The moment resistance of 8 mm-plate M-type is compared to 6 mm plate. Total four types ofPost-to-base connection are prepared and tested under pseudo-static reversed cyclic loading. Testresults showed that the yield moment of multi-directional connection is about 2 times higherthan that uni-directional connections. The ductility ratio of multi-directional connection determinedby EEEP was higher that that of uni-directional connection. It was becoming higheras the thickness of plate is increased. The Finite Element Analysis was conducted to estimatethe stress distribution behavior of tested connections. Results showed the failure of multi-directionaltype were caused by the split of pined hole and the shear failure of lifted part of post.
