Hysteresis behaviors and seismic damage model of recycled concrete filled square steel tube columns with the I-shaped steel

open access: yesJournal of Asian Architecture and Building Engineering
To investigate the hysteresis behavior and seismic damage performance of recycled concrete-filled square steel tube columns with I-shaped steel, nine column specimens were subjected to cyclic loading, aiming to acquire their load–displacement hysteretic ...

Centrifuge modeling of rocking-isolated inelastic RC bridge piers [PDF]

open access: yes, 2014
Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.

Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

open access: yesDeep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.
