This study addresses the long-term performance degradation of slopes reinforced with early-stage tension-type prestressed anchors in seismic zones. It establishes a time-variant reliability analysis framework for anchored slopes that concurrently accounts for anchor corrosion and seismic action. Based on electrochemica...
Resilient seismic design requires that structures exhibit excellent seismic performance and small residual deformation. Unbonded prestressed reinforced concrete (UBPRC) columns, with prestressed strands serving as self‐centering components, can effectively reduce residual displacement, which is of great significance...
To address the issues of unreasonable torque control and unclear failure modes in concrete anchorage systems with chemical anchors in hybrid bonded Fiber-Reinforced Polymer (FRP) strengthening system, this study focuses on the numerical simulation analysis of bolt-concrete anchorage systems. The mechanical characterist...
This study examines how inclination angles affect the pullout resistance of helical anchors embedded in clay. By validating a finite element approach with in-situ test data, a semi-cylindrical numerical model featuring a three-helix anchor was developed. We evaluated the structural response and failure mechanisms acros...
The anchorage body is a crucial subject of geotechnical research due to the unique collaboration between the rock and the bolt. The constant-resistance large-deformation (CRLD) bolt has demonstrated its unusual mechanical behaviors, but the mechanical performance of constant-resistance anchorage body (CRAB) remains l...
The fracture behavior of brittle rocks, like fractures in marble, is important for various engineering applications, including mining, underground facilities, hydraulic mining, and tunneling. While most of the prior work has focused on pure Mode I loading, rock structures undergo mixed-Mode I/II loading in which fractu...
