Abstract: The building A of Minda Plaza was adopted the SRC frame and shear wall structural system.Due to the functional need,the beams were deleted from the spindle-shape outmost frames,where the columns were arranged in an inclined orientation with the principal floor axes.The transfer story was of particular challenge,thus a new type of composite beam with encased built-up double steel sections was designed.The satisfactory performance of the new structural system was validated through quasi-static loading tests and shake-table test.The structure was exhibited to follow the failure mechanism of strong columns,weak beams,stronger transfer beams,and the strongest connection.The steel reinforced concrete transfer beams with double-steel sections had satisfactory bearing capacity and energy dissipation capacity,suitable to meet the requirements of functional limitation.
