Abstract ：
The tailings microcrystalline foamed plate (TMF plate), produced from industrial waste tailings, has limited research regarding its use in high-performance building walls. Its brittleness under stress poses challenges. To improve its mechanical properties, a prefabricated light steel-tailings microcrystalline foamed plate composite wall (LS-TMF composite wall) has been proposed. This LS-TMF composite wall system integrates assembly, sustainability, insulation, and decorative functions, making it a promising market option. To study the in-plane performance of the composite wall, compression and seismic performance tests were conducted. The findings indicate that the light steel keel, steel bar, and TMF plate in the composite wall demonstrated good working performance. Strengthening the TMF plate enhanced the restraint on the light steel keel and improved the composite wall's compressive performance. Increasing the thickness of the light steel keel further improved the compressive stability. Under horizontal cyclic loading, failure occurred at the light steel keel embedding location. Increasing the strength of the TMF plate was beneficial for the seismic performance of the composite wall. This structural configuration-incorporating light steel keels, TMF plates, and fly ash blocks-enhanced thermal insulation and significantly improved in-plane stress performance. However, the splicing plate structure adversely affected the seismic performance of the composite wall.

Abstract ：
There is a growing interest in the development of precast structures. In this paper, a semi-precast high-strength recycled aggregate concrete (RAC) column with high-strength reinforcement was studied, which was consisted of cast-in-situ core concrete surrounded by a precast external shell. Six full-scale columns were fabricated and tested under cyclic lateral load, of which two were cast-in-situ columns and four were semi-precast columns. The penetration of shear reinforcement between precast external shell and cast-in-situ core column, core column diameter and axial load were the major design parameters. The test results showed that all specimens exhibited a good deformation capacity with an ultimate drift ratio greater than 3%. The semi-precast columns had comparable seismic performance with the cast-in-situ columns, indicating that the penetrating shear reinforcement and the core column diameter had little effect on the seismic performance. The core column diameter could be selected according to the practical engineering requirements. Increasing the axial load can significantly improve the lateral load-carrying capacity of the specimens, but would result in larger residual drift ratio, which was adverse to the repairability of the specimens. The flexural deformation and the deformation resulting from slippage of longitudinal reinforcement in the concrete foundation accounted for 50%-80% and 10%-20% of the lateral displacement, respectively, which should not be ignored in the deformation calculation; however, the shear deformation can be ignored. The optimized models applicable to calculate the F-Delta curves of semi-precast high-strength RAC columns with high-strength reinforcement were proposed. Parametric analysis based on the optimized models was carried out to develop N-M curves for various precast external shell or core column concrete strength, and core column diameters.
