Abstract: In order to study the aseismic performance of the energy-saving block and invisible multi-ribbed frame composite wall after two-sided fire in terms of hysteretic behaviors, of stiffness degradation, of ductility, of energy dissipation capacity, and etc., 1/2 scale six specimens of the wall with plastering and six contrast specimens without plastering were fabricated and six specimens with plastering and three specimens without plastering were tested under an ISO-834 standard two-sided fire. Thereafter, these specimens were subjected to an in-plane cyclic load to evaluate their post-fire seismic performance. The influences of axial compression ratio, of fire time, with or without plastering on the skeleton curve and hysteretic characteristics of the walls were mainly considered in the test. Research results show that: for specimens with the same axial compression ratio, the fire time increases, and the slope of the skeleton curve decreases; compared with normal temperature specimens, the peak load value of specimens subjected to fire decreases, indicating that fire will reduce the shear capacity and stiffness of composite walls. The slope of skeleton curve of composite wall with plastering is greater than that of composite wall without plastering, and the yield load and peak load increase significantly. Under the same fire exposure time, the rise amplitude decreases with the increase of axial compression ratio. When the axial compression ratio is the same, the yield load and peak load of the specimens decrease with the increase of the fire time. Under the same fire time (45 min), with the increase of axial compression ratio, the yield load and peak load of the specimen are increased. The ductility coefficient of the composite wall after 0 min-30 min two-sided fire increases with the extension of fire time, and decreases with the extension of fire time at 30 min-45 min. After fire, the ductility coefficient of composite wall decreases with the increase of axial compression ratio. The greater the axial compression ratio, the more the ductility of the component decreases. With the same axial compression ratio, the dissipative energy of each stage of the wall decreases significantly with the increase of the fire time; and the dissipative energy of each stage of the wall decreases obviously with the increase of axial compression ratio when the fire time is the same. Under the same axial compression ratio and fire time, the single-circle dissipation energy of the wall without plastering is obviously reduced. The research results are of a great significance for the safety identification and for the repair and reinforcement of the energy-saving block with an invisible multi-ribbed frame structure after fire.
