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

Longitudinal combined seismic mitigation systems and optimal control for long span triple-tower suspension bridges

Advances in Bridge Engineering
Compared with the two-tower suspension bridge, the seismic response of the middle tower is crucial for the seismic design of triple-tower suspension bridges. A finite element model was developed for a suspension bridge.

Seismic resilience design of prefabricated modular pressurized buildings

Resilient Cities and Structures
The seismic intensity is generally high in the Qinghai-Tibet Plateau region of China. The seismic performance of the new prefabricated modular pressurized buildings used to solve the plateau response is insufficient.

One-dimensional physical reference models for the upper mantle and transition zone: combining seismic and mineral physics constraints [PDF]

One-dimensional seismic reference models are known to be a nonunique solution to global seismic data, hampering an interpretation in terms of physical structure. Here we test the compatibility of the simplest hypothesis of a mantle convecting as a whole,

Design Internal Forces of Non‐Dissipative Members in CBFs With Regular and Irregular Brace Configurations

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Steel Concentrically Braced Frames (CBFs) are widely used in seismic regions, with chevron and split‐X configurations commonly adopted for their structural efficiency and architectural flexibility. Although extensive research has been carried out on these systems, the effectiveness of the formulations available in the literature for estimating

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 ...
