Response of framed buildings to twin tunnelling in sand: a numerical investigation

Tunnel excavation induces ground movements and structural deformation, with the response of surface-framed buildings becoming particularly complex under twin-tunnel construction. This paper presents a parametric numerical study of the deformation responses of framed buildings on...

Effect of scour- and cyclic loading-induced soil-monopile stiffness degradation on long-term dynamic response of support structures for OWT

Offshore wind power has expanded rapidly, making the long-term safety and stability of offshore wind turbine support structures a key concern in design and maintenance. Changes in structural natural frequencies can trigger resonance if they enter the 1P or 3P rotor excitation ban...

Exploring the invisible: Multi-scale geophysical studies to delineate granite-hosted Li-bearing pegmatites of the Seixo Amarelo-Gonçalo region, Portugal

A holistic geophysical approach was conducted to assess the effectiveness of electromagnetic, direct current resistivity, induced polarization, magnetic and Ground Penetrating Radar (GPR) methods for exploration of pegmatite sills in the Seixo Amarelo-Gonçalo region of central ea...

Petrophysical attributes of the Seixo Amarelo-Gonçalo Li-bearing aplite-pegmatites (Guarda-Belmonte area, central Portugal)

Lithium-bearing pegmatites of the Seixo Amarelo-Gonçalo area are hosted within twomica granites of the Guarda-Belmonte area in central Portugal. The pegmatites, often concealed beneath cover material, occur at sizes difficult to detect via airborne geophysical methods but may be...
