TL;DR: In this paper, a 3D random aggregate simulation (3D-RAS) structure was used to model aggregate shapes of 3D concrete, where the shape, size and spatial distribution of the aggregate particles resemble real concrete in the statistical sense, and fundamental aggregate diameters within the same gradation were assumed to follow random Gaussian distributions.

TL;DR: In this paper, a novel sealing device that has a minimal effect on the mechanical behavior of concrete specimens is proposed, which connects one side of silicon plates to a specimen using two specially designed clamps, instead of adhesive and screws the other side of the plates together to a steel plate.

TL;DR: In this article, a long-term field measurement was carried out during excavating and backfilling construction of an anchored sheet pile wall structure, and the results indicated that the lateral earth pressure from the soil drove the deformation of the anchored sheet piles and that the soil movement acted as a “damper” to slow down deformation processes by resisting the tubular pile in the soil-structure interaction system.

TL;DR: Zhang et al. as discussed by the authors extended the static contact problem of crack faces to include dynamic contact and crack propagation based on the relevant literature, and the scaled boundary finite element method was used to solve dynamic crack face contact and cracks propagation problems.

TL;DR: In this paper, a series-stiffness, broadband and magnetorheological intelligent vibration absorbing device was proposed to reduce the low-frequency interference of flexible demands and high frequency vibration of rigid demand.
