Study on Dynamic Characteristics of Long-Span Highway-Rail Double-Tower Cable-Stayed Bridge
BuildingsThe long-span dual-purpose highway-rail double-tower cable-stayed bridge has the characteristics of a large span and large load-bearing capacity. Compared with the traditional cable-stayed bridge, its wind resistance and seismic resistance are weaker ...

Journal of Low Frequency Noise, Vibration and Active Control, 2021 With the continuous service time, long-span track cable-stayed bridges are inevitably affected by material time-varying and fatigue load periodic effects, and permanent down-deflection phenomenon is inevitable.

Structural Responses Estimation of Cable-Stayed Bridge from Limited Number of Multi-Response Data
Sensors, 2022 A cable-stayed bridge is widely adopted to construct long-span bridges. The deformation of cable-stayed bridges is relatively larger than that of conventional bridges, such as beam and truss types.

ULTIMATE STRENGTH ANALYSIS OF LONG-SPAN CABLE-STAYED BRIDGES
Doboku Gakkai Ronbunshu, 1998 斜張橋は益々長大化する傾向にあり, その終局弓鍍を正確に推定することが設計上重要な課題となっているが, 長大斜張橋, 特に軸力が支配的となる主桁の耐荷力評価のための具体的設計法は確立されていないのが現状である. 斜張橋では, 長支間においても幾何学的非線形性の影響は小さいため, 断面の塑性化が終局強度に及ぼす影響は著しく, 弾性有限変位解析のみで終局強度を正確に評価することは困難と考えられる. したがって, 長大斜張橋の安全性と経済性を評価するためには, 材料非線形を考慮し, 終局状態での両者の非線形性が同時に考慮できる複合非線形解析を用い, その挙動を検討しておく必要がある. 本論文では, 多室箱桁の複合非線形性を考慮した三次元解析法を定式化し, 長大斜張橋の終局挙動を解析するプログラムを開発した.

TreeSpider: In‐Canopy Exploration With Tether‐Based Aerial Modular Arms
Advanced Robotics Research, EarlyView.A tethered drone with perching arms and a 360° ring enables unprecedented maneuverability within dense forest canopies. By dynamically adjusting tether length and decoupling pitch from the frame, it navigates between branches, senses multiple trees, and interacts physically with foliage.

Design of a Reconfigurable Microfluidic System Enabled by Magnetic Miniature Robots
Advanced Intelligent Systems, EarlyView.Magnetic miniature robots are integrated into microfluidic chips to achieve real‐time reconfiguration. By external magnetic actuation, the robots perform sorting, mixing, flow regulation, and bubble removal on demand. This versatile platform eliminates the need for complex on‐chip hardware and enables adaptive control for biological and chemical ...
