Minimum Embedded Length of Hybrid Steel Coupling Beam

The purpose of this study was to estimate the minimum embedded length of the hybrid steel coupling beam. Cyclic loading tests for six hybrid steel coupling beams were performed. Primary variables of the tests were the embedded length of the steel beam. Test results indicated that the embedded length of the steel beam and top - seat angles had influence on the shear strength and energy dissipation capacity of the hybrid steel coupling beam. Required embedded length of hybrid steel coupling beam was proposed. Minimum embedded length was expressed as function of concrete compressive strength and plastic shear strength of the steel coupling beam.
