Note. SC is the dimensions of the side columns; IC is the dimensions of the inner columns; SB is the dimensions of the side beams; MB is the dimensions of the middle beams; A_BRB is the sectional area of HPBRBs. The symbol “□” represents the square steel pipe, which could be regarded as the box-section columns.
