A unified degrading shear strength model for rectangular and circular solid/hollow RC columns

Reliable quantification of shear strength in the plastic hinge regions of reinforced concrete (RC) columns is crucial for seismic design. However, existing shear strength models often rely on the linear superposition of multiple shear-resisting contributions, an approach that has...

Seismic shear strength of thin-walled circular hollow RC bridge piers considering flexural-shear interaction

The thin-walled circular hollow reinforced concrete (RC) bridge piers provide favorable material efficiency, but their seismic shear strength is difficult to evaluate because hollow-section geometry and post-yield flexural damage can jointly reduce the available shear-transfer ca...
