| 2 | Seismic behavior of steel tubular bridge columns equipped with low-yield-point steel plates in the root replaceable pier显示文摘To enable rapid recovery of a steel bridge column after an earthquake,a novel tubular-section steel bridge column equipped with low-yield-point(LYP)steel tubular plates in the root replaceable pier is proposed.For the purpose of discussing the seismic behavior of the novel steel bridge column,quasi-static tests and finite element simulation analyses of the specimens were carried out.The effects of parameters such as the axial compression ratio,eccentricity,and thickness and material strength of the tubular plate in the energy-dissipating zone are discussed.Experimental results from seven specimens that were subjected to four failure modes are presented.The damage to the quasi-static specimens is localized to the replaceable energy-dissipating pier.The seismic behavior of the novel steel bridge columns is significantly influenced by the axial compression ratio and eccentricity of specimens.Numerical results show that the high stress area of the specimens is mainly concentrated in the connection zone between the LYP steel tubular plate and the bottom steel plate,which is consistent with the position of the quasi-static specimen when it was prone to fracture.Finally,a calculation formula is proposed to facilitate the capacity prediction of this new steel tubular bridge column under repeated loading. | Li Haifeng Jiang Kaiping Chen Yisu Han Xue | 2023 | Earthquake Engineering and Engineering Vibration2023，22，2： | 0 |
| 3 | All-perfluoropolymer,nonlinear stability-assisted monolithic surface combines topology-specific superwettability with ultradurability显示文摘Developing versatile and robust surfaces that mimic the skins of living beings to regulate air/liquid/solid matter is critical for many bioinspired applications.Despite notable achievements,such as in the case of developing robust superhydrophobic surfaces,it remains elusive to realize simultaneously topology-specific superwettability and multipronged durability owing to their inherent tradeoff and the lack of a scalable fabrication method.Here,we present a largely unexplored strategy of preparing an all-perfluoropolymer(Teflon),nonlinear stability-assisted monolithic surface for efficient regulating matters. | Wanbo Li Chiu-wing Chan Zeyu Li Sin-Yung Siu Siyu Chen Han Sun Zeyu Liu Yisu Wang Chong Hu Nicola Maria Pugno Richard N.Zare Hongkai Wu Kangning Ren | 2023 | The Innovation2023，4，2： | 0 |
