Shear critical R/C columns under increasing axial load [PDF]
, 2020 Structural elements in old reinforced concrete (R/C) frame buildings are often prone to shear or flexure-shear failure, which can eventually lead to loss of axial load capacity of vertical elements and initiate vertical progressive collapse of a building.

Small-strain stiffness degradation of artificially cemented sands [PDF]
Géotechnique Letters, 2020 This paper investigates the degradation of small-strain stiffness of artificially cemented sand subjected to isotropic loading cycles using bender elements. Samples with cement contents of 3 and 5% were allowed to cure for 72 h using fast-setting Portland cement under a constant confining pressure of 200 kPa.

Small strain stiffness and stiffness degradation curve of Bangkok Clays
Soils and Foundations, 2013 AbstractThe small strain stiffness and the stiffness degradation curve of soils are required in advanced numerical analyses of geotechnical engineering problems. The shear modulus at small strain (Gmax) and the reference shear strain parameter (γ0.7) are, for instance, two of the input parameters in a finite element analysis with the hardening soil ...

Effect of Fast Loading on the Seismic Performance of SRUHSC Frame Structures
Buildings, 2022 Due to the high compressive strength and durability of ultra-high-strength concrete, SRUHSC (steel-reinforced ultra-high-strength concrete) frame structures have been used extensively in super-high-rise buildings.

Journal of Marine Science and Engineering, 2023 This paper studies the compressive failure behavior of pw-GFRP (plain-woven glass fiber reinforced polymer) sandwich composite L-joints for ships. Six L-joint specimens were subjected to ultimate compressive tests, which show that damage and stiffness ...

Fatigue crack growth in thin notched woven glass composites under tensile loading. Part II: modelling [PDF]
, 2011 Fatigue propagation of a through-the-thickness crack in thin woven glass laminates is difficult to model when using homogeneous material assumption. Crack growth depends on both the fatigue behaviour of the fibres and of the matrix, these two phenomena ...
