Shear strength distribution of district heating pipe under accelerated aging condition with respect to PU foam density

open access: yesPolymer Testing, 2022
The European standard EN253 for bonded pipe systems for District Heating(DH) using polyurethane foam thermal insulation applied to bond to a steel service pipe and a polyethylene casing has been proposed to validate the residual life and soundness of an ...

The Tension-Shear and Compression-Shear Joint Strength Model for Unsaturated Clay and Its Application to Slopes

open access: yesFrontiers in Earth Science, 2022
The capillary component and adsorptive component of matric suction differently impact the soil strength. Due to the cavitation effects of pore water, the adsorption effect dominates the behavior of soil when matric suction exceeds the cavitation tension.

The temperature-dependent shear strength of ice-filled joints in rock mass considering the effect of joint roughness, opening and shear rates [PDF]

open access: yesThe Cryosphere, 2023
Global warming causes many rockfall activities in alpine mountains, especially when ice-filled joints in the rock mass become thawed. The warming and thawing of frozen soils and intact rocks have been widely studied in the past several decades; however ...

Modified Equation of Shear Strength with Respect to Saturation

open access: yesApplied Sciences, 2023
Unsaturated soil shear strength is a significant topic in geotechnical engineering. The measurement of unsaturated soil properties such as shear strength and matric suction could be costly, hard, time-consuming, and often impractical to obtain.

An Advanced Shear Strength Criterion for Rock Discontinuities Considering Size and Low Shear Rate

open access: yesApplied Sciences, 2020
The shear strength of the rock discontinuities under different shear rates is of great importance to evaluate the stability of rock mass engineering, which is remarkably influenced by the size effects induced by both the length and the undulated ...

Shear strength properties of hybrid (hinoki cypress and Japanese cedar) cross-laminated timber

open access: yesJournal of Wood Science, 2021
In this study, the out-of-plane shear strength of hybrid cross-laminated timber (CLT) with outer layers of hinoki (hinoki cypress, Chamaecyparis obtusa) and inner layers of sugi (Japanese cedar, Cryptomeria japonica) is investigated for four different ...

Shear Strength Prediction Equations and Experimental Study of High Strength Steel Fiber-Reinforced Concrete Beams with Different Shear Span-to-Depth Ratios

open access: yesApplied Sciences, 2019
Conducting research on steel fiber-reinforced concrete (SFRC) beams without stirrups, particularly the SFRC beams with high-strength concrete (HSC) and high-strength steel (HSS) reinforcing bars is essential due to the limitation of test results of high ...

Evolution of Peak Shear Strength of Rock Fractures Under Conditions of Repetitive Dry and Wet Cycling

open access: yesFrontiers in Earth Science, 2022
The degradation of shear mechanical properties of rock fracture surfaces was determined after applying multiple dry-wet cycles. Artificially fractured feldspathic sandstone specimens were soaked in chemical solutions with pH values of 2, 7, and 12 for 3,
