The core components of High-Temperature Gas-cooled Reactors (HTGRs) are primarily composed of graphite materials. Under high temperature and irradiation, the mechanical properties of graphite materials undergo changes, which ultimately affect the load-bearing capacity of the core components. Therefo…

To address the challenges of high difficulty and low efficiency in traditional 3D mesoscale concrete numerical models, which hinder their application, a frictional debonding failure method for 3D models is adopted. This approach avoids the complexity of traditionally establishing physical transition…

Based on equivalent homogenization theory, a multi-scale simulation study was conducted to investigate the influence of mesoscopic aggregate factors on the mechanical behavior of reinforced concrete (RC) columns under eccentric compression. This was achieved by establishing both mesoscopic numerical…

The significant differences in shrinkage and creep characteristics between ultra-high performance concrete (UHPC) and normal concrete (NC) lead to markedly distinct long-term deflection growth in steel-UHPC composite beams versus steel-NC composite beams. To scientifically and rationally calculate t…

The energy method is favored by researchers because it avoids the complex intermediate stress analysis of instability failure in spatial steel structures. Large-span spatial steel structures represent a critical structural form in engineering. Due to their numerous degrees of freedom and the complex…

Addressing the issue that existing slope deformation predictions rarely consider the spatial variability of soil property parameters, this paper proposes a stochastic deformation prediction method for high fill slopes. By analyzing the one-dimensional consolidation creep characteristics of loess, a …
