1. A construction, comprising:
a beam-column joint structure comprising:
a hollow rectangular steel frame consisting of a first sidewall, a second sidewall, a third sidewall and a fourth sidewall, wherein the first sidewall is arranged opposed to the third sidewall, and the second sidewall is arranged opposed to the fourth sidewall;
a plurality of H-beams, wherein each of the plurality of H-beams is fixedly attached to an outer surface of at least some of the first sidewall, the second sidewall, the third side wall and the fourth sidewall; and
a first steel plate fixed in and near the top of the hollow rectangular steel frame and a second steel plate fixed in and near the bottom of the hollow rectangular steel frame;
wherein a first axis is defined by a central position of the first sidewall and a central position of the third sidewall;
wherein a second axis is defined by a central position of the second sidewall and a central position of the fourth sidewall;
wherein at least one of the plurality of H-beams is offset from the first axis in the transverse direction of the first sidewall or the third sidewall;
wherein at least one of the plurality of H-beams is offset from the second axis in the transverse direction of the second sidewall or the fourth sidewall; and
wherein the first steel plate comprises a plurality of first through holes therein and the second steel plate comprises a plurality of second through holes therein and wherein the plurality of first through holes are generally aligned with the plurality of second through holes for rebars to pass through; and
a precast reinforced concrete (RC) column comprising a precast body with the rebars extending from the top surface;
wherein the rebars are generally distributed near the circumference of the top surface and form a space therein and wherein the size of the space is sufficient for accommodating an end of the hollow rectangular steel frame;
wherein the precast RC column further comprises a second main spiral stirrup provided to surround some of the rebars and four second auxiliary spiral stirrups provided near four top corners of the precast body and surrounding the rebars provided at the four top corners of the precast body.
