Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

Deep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Mitigating surcharge‐induced column‐head cracking in double‐deck shield tunnels using hyperelastic bearing joints

Deep Underground Science and Engineering, EarlyView.
A staged three‐dimensional nonlinear soil–structure interaction (SSI) model is established, in which the initial geostress state, tunnel excavation, lining installation, delayed activation of the internal frame, and subsequent surcharge loading are simulated sequentially.

Numerical and Experimental Evaluation of a Simplified Lateral Spring Formulation for Rocking Structures

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been

Seismic Response of Existing Masonry‐Infilled RC Frame Structures Retrofitted with Steel Exoskeletons

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Considering the needs for reducing carbon emissions and except for extreme cases of very degraded existing structures, research on technologies allowing continued use or upgrading of older buildings has become a priority topic. Generally, research on upgrading of reinforced concrete frame structures certainly has a prominent role, because of ...

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Influence of the Boundary Conditions on the Seismic Response of Existing Masonry Infills From In‐Plane and Dynamic Out‐of‐Plane Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Despite increasing attention to the seismic performance of masonry infills, their out‐of‐plane dynamic behaviour remains insufficiently explored, particularly under pre‐existing in‐plane damage. This study presents a comprehensive experimental campaign designed to investigate the seismic behaviour of an existing weak masonry infill typology ...
