Abstract—This paper presents the performance of a full-scale wall-slab joint in tunnel form system subjected to lateral cyclic loading. The objectives are to determine seismic behavior of the hysteresis loops, strength capacity, stiffness, ductility, damage states and modes of failure. Wall-slab joint was tested up to failure drift of 2.5%. Theoretical equations were developed to calculate ductility and moment resistance of wall section. From visual observation, a lot of cracks were occurred at joint and upper part of wall panel. Spalling of concrete was observed at the top part of the joints and fractured of longitudinal reinforcement bar when the wall is pushing under out-of-plane direction. Validation between the theoretical values and experimental results were compared. There was a good agreement between them. Therefore, the moment resistance and ductility of the joint were determined and designed accordingly.
Index Terms—Damage states, ductility, strength, stiffness.
