Abstract ：
To promote the green development of urban buildings constructed with recycled materials, experimental and numerical studies were conducted on the flexural behavior of high-strength recycled aggregate concrete (HSRAC) slabs in this paper. Six full-scale one-way slabs, compromising of four HSRAC slabs and two high-strength natural aggregate concrete (HSNAC) slabs, were tested under one-way repeated loading. Impacts of varied parameters (steel trusses, concrete type, reinforcement ratio and slab thickness) on the flexural behavior were clarified. The test results indicated that arrangement of steel trusses can effectively limit the crack development and enhance the post-cracking stiffness by a maximum of 20 %. The flexural behavior was comprehensively improved including resistance, deformability, stiffness and restoration capacity as the reinforcement ratio increased by 51 %. Thicker slab (150 mm) performed better flexural resisting capacity (over 50 %) and service stiffness (over 70 %) at a cost of ductility loss. HSRAC slabs possessed comparable performance with the HSNAC counterpart, which is a strong affirmation for the promising application of such slabs. Practical finite element (FE) models were then established and verified with test results, and a detailed parametric study was also conducted to provide reference for designing additional important parameters. Finally, a database of 84 bending members was collected and a comparable analysis was carried out to verify the correctness of the tests with a reliability interval of 92 % and enrich the database. Relevant NAC design specifications were evaluated and proved available for safely and accurately predicting the flexural capacity and yield deflection of the proposed slabs, with a deviation range within 15 %.

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.
