Monotonic and cyclic load of pine wood under uniaxial compression: experiments and modeling [PDF]

open access: yesE3S Web of Conferences, 2023
To analyze the behavior of wood under uniaxial monotonic deformation, we applied an analytical model to separately control of the pre-peak and post-peak branches of the load-displacement curve.

Cyclic overlay model of py curves for laterally loaded monopiles in cohesionless soil [PDF]

open access: yesWind Energy Science, 2023
The bearing behaviour of large-diameter monopile foundations for offshore wind turbines under lateral cyclic loads in cohesionless soil is an issue of ongoing research. In practice, mostly the p–y approach is applied in the design of monopiles. Recently,

Experimental Investigation of Loading Frequency Influence on a Strength of Asphalt Interlayer Bonding [PDF]

open access: yesArchives of Civil Engineering, 2020
The article presents a new approach to testing the strength of asphalt interlayer bonding. Two loading methods were used: static load and cyclic load. Before carrying out static shear strength tests, the interlayer bonding was subjected to cyclic loads ...

Inclination Effect of Cyclic Load Synchronous with Lateral Static Load on Pile Group in Sandy Soil

open access: yesDiyala Journal of Engineering Sciences, 2023
In general Pile foundations are often subject to more than one load in nature. Two loadings, when simultaneous, cause serious problems in the bearing capacity.

A model test study on the parameters affecting the cyclic lateral response of monopile foundations for offshore wind turbines embedded in non-cohesive soils [PDF]

open access: yesWind Energy Science, 2022
During their service life, monopiles supporting offshore wind turbines are subjected to a large number of lateral cyclic loads resulting from complex environmental conditions such as wind and waves varying in amplitude, direction, load eccentricity and ...
