Abstract

The same two straight mortise-tennon joints in the base of melon-column (SJ for short) and penetrated mortise-tennon joints (PJ for short) were made with related rules. Relations of moment-rotation, length of the tenon pulled out-rotation and failure modes were got through monotonic loading test. Experimental study showed the main damage type of SJ was pulling out, while two damage types of PJ were bending damage and transverse tearing failure respectively. When under the action of bending moment, the resisting torque of SJ was synthesized by vertical load of columns, while that of PJ was mainly synthesized by local compresssive stress and friction on upper and lower surface of the tennon. In addition, the pulling size of tennons was associated with the heigth of tenon and relative rotation of beam and column.
