Investigation and Control of VIVs with Multi-Lock-in Regions on Wide Flat Box Girders

open access: yesJournal of Control Science and Engineering, 2017
On the preliminary designing of a wide flat box girder with the slenderness ratio 12, vertical and torsional vortex-induced vibrations (VIV) are observed in wind tunnel tests.

Maneuverable Multilegged Locomotion through Anisotropically Arranged Soft Backbones in a Single‐Actuator Modular Miniature Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
A modular eight‐legged robot exploits anisotropically oriented soft I‐beam backbones to transmit vibration from a single unbalanced‐mass actuator, producing frequency‐dependent multimodal gaits. A pseudo‐rigid‐body model enables high‐fidelity MuJoCo simulation, while Bayesian parameter identification and reinforcement learning yield robust control ...

Uncoupled approaches for walking-induced vertical vibration of a lively footbridge [PDF]

open access: yes, 2016
The recent trend towards the design of flexible footbridges, characterized by a low ratio between permanent and variable load, has made them more sensitive to dynamic forces induced by pedestrians.

Software for calculation of pedestrian-induced vibration of floors

open access: yes, 2022
Trendovi u savremenoj arhitekturi, koji diktiraju projektovanje komercijalnih i stambenih zgrada sa otvorenim prostorom, prouzrokovali su problem prekomernih vibracija međuspratnih konstrukcija velikih raspona usled aktivnosti ljudi koji se po njima kreću. Saniranje prekomernih vibracija već izgrađenih konstrukcija je skupo i vremenski zahtevno.

Physicochemical and Mechanical Characterization of Commercial Collagen‐Based Wound Dressings

open access: yesAdvanced NanoBiomed Research, EarlyView.
Commercial collagen‐based wound dressings are systematically compared to reveal how porous architecture governs hydration‐driven swelling and mechanical adaptation. Distinct structure–function relationships are identified, showing that wet‐state elasticity and conformability emerge from material composition and processing rather than manufacturer ...

Vertical ground reaction forces on rigid and vibrating surfaces for vibration serviceability assessment of structures [PDF]

open access: yes, 2018
Lightweight structures are sensitive to dynamic force generated by human walking and consequently can exhibit excessive vibration responses. The imparted forces, known as ground reaction forces (GRFs), are a key input in the vibration serviceability ...

Treatments on Polypropylene Macro Synthetic Fibers for Improving Adhesion in Structural Concrete Reinforcement: A Systematic Review

open access: yesJournal of Applied Polymer Science, EarlyView.
Surface functionalization of polypropylene macrofibers to enhance fiber‐matrix interfacial bonding. ABSTRACT Concrete is the most used higher compressive strength‐building material, albeit brittle to tensile, and flexural loads. Polypropylene (PP) synthetic polymeric macrofibres are commonly employed as reinforcement material to prevent this situation ...
