Dynamic Response of Cement–Fly Ash Mixed Pile Composite Foundation Under Wave Load

open access: yesFrontiers in Earth Science, 2022
CFMPs (cement and fly ash mixing piles) are used to reinforce fly ash foundation to solve the problem of a large amount of fly ash accumulation in coastal areas.

The Effect of Fiber Orientation and Stress Ratio on the Crack Growth Behavior of Fiber Metal Laminates (FMLs)

open access: yesInternational Journal of Technology, 2018
The crack growth behavior of fiber metal laminates (FMLs) with fiber orientations of 90°/0° and 45°/45° to load direction was investigated with varying stress ratios of the cyclic constant load.

Numerical Investigation of the Influence of the Drill String Vibration Cyclic Loads on the Development of the Wellbore Natural Fracture

open access: yesEnergies, 2021
Wellbore instability is one of the most serious issues faced in the drilling process. During drilling operations, the cyclic loads applied on the fractured formation progressively modify the initial parameters (i.e., length and width) of the fractured ...

Investigations on influences of Engineered Cementitious Composites (ECC) on pull-out properties of studs in steel-concrete composite bridge

open access: yesCase Studies in Construction Materials, 2023
Stud plays an important role in the connection of steel-concrete composite bridge (SCCB). The stud is under pull-out load in the negative moment zone of SCCB.

Inconsistent effect of dynamic load waveform on macro- and micro-scale responses of ballast bed characterized in individual cycle: a numerical study

open access: yesRailway Engineering Science, 2023
Cyclic load is widely adopted in laboratory to simulate the effect of train load on ballast bed. The effectiveness of such load equivalence is usually testified by having similar results of key concerns of ballast bed, such as deformation or stiffness ...

Horizontal Cyclic Bearing Characteristics of Bucket Foundation in Sand for Offshore Wind Turbines

open access: yesEnergies
During the service period, the offshore wind turbine foundation mainly bears the wind load from the upper structure and the periodic loads such as wave load and sea currents from the lower structure. Long-term cyclic loads have an important impact on the

Piles Subjected to Torsional Cyclic Load: Numerical Analysis

open access: yesFrontiers in Built Environment, 2019
Pile foundations supporting large structures (such as high-rise buildings, oil drilling platforms, bridges etc). are often subjected to eccentric lateral load (in addition to the vertical loads) due to the action of wind, waves, high speed traffic, and ...

The effect of varying loading directions and loading levels on crack growth at 2D- and 3D-mixed-mode-loadings [PDF]

open access: yesFracture and Structural Integrity, 2016
While product’s operation the loading situation commonly changes. The local loading situation on an existing crack then can shift to a combined loading, composed of mode I, mode II and mode III, and consequently influence the product’s durability ...

A load capacity of cyclic loaded reinforced concrete beams

open access: yesBudownictwo i Architektura, 2014
In this paper, an effect of cyclic and variable loads on the capacity of reinforced concrete beams is investigated. The study was conducted on 28 reinforced concrete beams including 12 two-span beams - statically indeterminate and 16 simply supported ...

A creep damage constitutive model of loaded yellow sandstone under cyclic water intrusion

open access: yes矿业科学学报
For the rock mass of roadbed slope, its long-term stability is often compromised due to the lasting impact of both water-drying cycle and unidirectional load under rainfall.
