Engineering Structures, 2023 This work aimed to perform the numerical and experimental analysis of three test setups (bending, vertical shear, and inclined shear) of CLT used to determine the rolling shear stiffness and strength. CLT specimens were manufactured with four different Brazilian wood species and two-component polyurethane adhesive.

Duration-of-load and size effects on the rolling shear strength of cross laminated timber
, 2015 In the beginning of the twenty-first century, the largest mountain pine beetle (MPB) outbreak ever recorded struck western Canada. A huge volume of MPB-attacked lodgepole pine is expected to hit the BC forest industry in the next decade. Technologies to convert MPB-attacked lumber into engineering wood products are urgently required.

Influence of technical characteristics on the rolling shear properties of cross laminated timber by modified planar shear tests [PDF]
Maderas: Ciencia y Tecnología, 2018 Rolling shear properties of cross laminated timber are important mechanical properties for its structural application. To evaluate the influence of technical characteristics such as edge-gluing and gap size in the cross layers, on the measurement of ...

Optimizing Lumber Densification for Mitigating Rolling Shear Failure in Cross-Laminated Timber (CLT) [PDF]
Construction MaterialsRolling shear in cross-laminated timber (CLT) has been identified as the governing factor influencing design value. Likewise, densification has been found to be an effective method of enhancing the rolling shear strength of lumber and in turn, CLT.

Punching shear strength of steel fibre reinforced lightweight concrete slabs. [PDF]
, 1981 One of the problems in slab-column connections is the punching shear failure at over loads. Such failures are sudden and catastrophic, and are undesirable since they do not allow an overall yield mechanism to ...

Experimental studies of scale effects on shear strength, and deformation of rock joints [PDF]
, 1980 The effect of scale on shear strength is studied by performing direct shear tests on different sized samples of large joints. A rubber moulding system is used to obtain impressions of the roughness from a variety of natural joint surfaces.

Rolling shear strength of timber boards
Bulletin of Kharkov National Automobile and Highway University, 2020 Abstract. Problem Rolling shear strength and rolling shear modulus are important mechanical and elastic properties that have emerged recently and are needed when calculating multi-storey CLT buildings. Goal Rolling shear is a new task that requires determining the influencing factors on it’s magnitude as an indicator of the strength of the boards in ...

Isosorbide-Based Optically Clear Adhesives With Ultrahigh Transparency and Rapid Strain Recovery for Flexible Displays. [PDF]
Adv Sci (Weinh)Biomass‐derived isosorbide‐based PUDA crosslinker enables optically clear adhesives with ultrahigh transparency (99.8%), rapid strain recovery, and stable adhesion for flexible displays. ABSTRACT Flexible and foldable displays require optically clear adhesives (OCAs) that combine ultrahigh optical transparency with mechanical resilience under repeated ...
