    Study on dynamic strength criterion of sandstone under the coupling influence of confining pressure, bedding angle and impact pressure by Wenbing Fan, Junwen Zhang, Yang Yang, Jiaqi Wang, Lin Mao, Shaokang Wu, Yang Zhang, Xukai Dong, Yifan Huang, Chuanzhong Jiang

    Published 2025-06-01
    “…Specifically, these criteria fail to adequately account for the coupled effects of confining pressure, bedding angle, and impact pressure on the dynamic evolution of sandstone strength parameters, including the internal friction angle (φ), cohesion (c), and Hoek–Brown parameter (m). To address this issue, this study systematically integrates experimental investigations and theoretical modeling to establish a dynamic strength criterion that incorporates multifactorial coupling effects. …”

    Axial Compressive Behavior of Outer Square Inner Circular Spontaneous Combustion Coal Gangue Concrete-Filled Double-Skin Steel Tubular Stub Column by Jinli Wang, Chunyuan Wang, Zhe Gao, Haoyan Wei, Zhengping Hu, Weiwei Wang

    Published 2024-12-01
    “…Utilizing crushed spontaneous combustion coal gangue as a coarse aggregate in concrete preparation effectively reduces reliance on natural resources and mitigates environmental pollution; however, the suboptimal workability of spontaneous combustion coal gangue coarse aggregate concrete (SCG-CAC) limits its engineering applications. To address this issue, this study places SCGCAC at the center of a CFDST (Concrete-Filled Double-Skin Steel Tubular) stub column. …”
