Performance-Based Seismic Design of Coupled Wall Systems Using Replaceable Fuse Elements
This study proposes a novel performance-based design framework for coupled reinforced concrete wall systems incorporating replaceable steel coupling beam fuses. Nonlinear dynamic analyses of a 30-storey archetype demonstrate that the fuse-coupled system achieves target drift ratios under MCE-level ground motions while concentrating inelastic damage in easily replaceable elements, reducing post-earthquake repair costs by an estimated 65%.
Long-Term Creep Behaviour of Cross-Laminated Timber Under Sustained Loading: A 10-Year Experimental Study
Results from a decade-long monitoring programme of 48 CLT panel specimens under sustained load at varying humidity conditions are presented. The study establishes new creep coefficients for 5-ply and 7-ply CLT layups, revealing that current Eurocode 5 kdef factors underestimate long-term deflections in 7-ply configurations by up to 18%.
Physics-Informed Neural Networks for Real-Time Structural Health Monitoring of Long-Span Bridges
A physics-informed neural network (PINN) framework is developed for damage detection and localisation using acceleration response data from bridge-mounted sensors. Validated against three years of continuous monitoring data from the Humber Bridge, the approach achieves 96.3% damage detection accuracy with a false positive rate below 2%.
Liquefaction-Induced Lateral Spreading Effects on Deep Foundations in Reclaimed Land: Centrifuge Testing and Numerical Validation
This paper presents results from 16 dynamic centrifuge tests investigating lateral spreading forces on pile groups founded in liquefiable reclaimed sand overlying dense gravel. Results reveal that existing JRA and Caltrans design guidelines can significantly underpredict pile demands when a non-liquefiable crust layer exceeds 4 metres in thickness.
Aerodynamic Mitigation of Vortex-Induced Vibrations in Supertall Buildings Using Corner Modifications and Porous Facades
Wind tunnel tests on 1:400 scale aeroelastic models of a 450m-tall prismatic tower investigate the combined effectiveness of chamfered corners, setbacks, and permeable facade screens in suppressing crosswind vortex-induced vibrations. The optimised configuration reduces peak crosswind accelerations by 42%.
Collapse Fragility Assessment of Pre-1980s Non-Ductile RC Frames Retrofitted with Buckling-Restrained Braces
Incremental dynamic analyses are performed on a suite of 20 archetype non-ductile reinforced concrete frames representative of 1960s–1970s construction in California, both in as-built condition and retrofitted with buckling-restrained braces. Results show that BRB retrofit reduces median collapse fragility by a factor of 3.2 to 4.7.
