The mortise pin is provided with a through-hole at a predetermined position. A bottom hole is provided at a bottom surface of the column in a manner that the bottom hole is adapted to receive the mortise pin. A horizontal hole is provided at a side face of the column at a position corresponding to the through-hole of the mortise pin. The composite beam is connected with the column by first inserting the mortise pin into the bottom hole of the column and then inserting a locking pin into the through-hole of the mortise pin and the horizontal hole of the column such that joint of the composite beam and the column is firmly secured. A method of joining a composite beam and a column is also disclosed.
