| 1 | Seismic performance of precast hollow bridge piers with different construction details显示文摘当前,预制的空具体的桥墩的设计计划将在中国在桥设计被采用,但是包括在高地震的风险区域的预制的部分墩的特定的设计细节没有代码。为有不同设计细节的空桥墩的地震性能的比较学习,空节桥码头的六个标本被设计并且测试。标本由整体的 cast-in-place 水泥桥墩组成,与联合的 cast-in-place 预制部分对的码头并且预制有干燥关节的部分具体的桥码头。结果证明所有标本有好排水量能力。有结合的对的海滨的桥墩展出更好的精力驱散能力和更高的力量。未结合的对的海滨桥墩显示更少的剩余塑料排水量和精力驱散能力。有在节的边的两个都结合的对的海滨的桥墩并且在节的中心未结合不仅展出更多的韧性能力和更少剩余塑料排水量,而且显示出更好的精力驱散能力。与对的桥列的试验性的结果相比,分析结果证明发达数字分析模型将提供合理、精确的结果。 | Zhiqiang WANG Jiping GE Hongyi WEI | 2014 | Frontiers of Structural and Civil Engineering2014，8，4： | 8 |
| 2 | Shake table study on precast segmental concrete double-column piers显示文摘Seismic capacity,including the ultimate load-carrying capacity and ultimate deformation capacity of precast segmental concrete double-column(PSCDC)piers with steel sleeve(SS)connection or grouted corrugated-metal duct(GCMD)connection,has been verified to be similar to those of cast-in-place(CIP)piers by quasi-static tests.However,the lack of knowledge of seismic response characteristics and damage process of PSCDC piers has limited their application in high-intensity seismic areas.Therefore,shake table tests,using variable types and intensities of seismic ground motions,were performed to investigate the seismic behavior of connection joints and to evaluate the seismic performance of PSCDC piers with SS and GCMD connections.Also,a finite element analysis(FEA)model was developed to study the influence of design parameters on the seismic behavior of the piers.The results showed that the main damage in PSCDC piers was caused by the cyclic opening and closing of connection joints.Under high-intensity ground motions,the PSCDC piers had a lower seismic performance than the CIP piers due to a significant decrease of their integrity and stiffness.The seismic performance of PSCDC piers is comparable to CIP piers when using an appropriate initial stress of the prestressing tendons. | Xia Zhanghua Ge Jiping Lin Youqin Qiu Faqiang | 2020 | Earthquake Engineering and Engineering Vibration2020，19，3： | 5 |
| 3 | Temporal and spatial cellular and molecular pathological alterations with single-cell resolution in the adult spinal cord after injury显示文摘Spinal cord injury(SCI)involves diverse injury responses in different cell types in a temporally and spatially specific manner.Here,using single-cell transcriptomic analyses combined with classic anatomical,behavioral,electrophysiological analyses,we report,with single-cell resolution,temporal molecular and cellular changes in crush-injured adult mouse spinal cord.Data revealed pathological changes of 12 different major cell types,three of which infiltrated into the spinal cord at distinct times post-injury.We discovered novel microglia and astrocyte subtypes in the uninjured spinal cord,and their dynamic conversions into additional stage-specific subtypes/states.Most dynamic changes occur at 3-days post-injury and by day-14 the second wave of microglial activation emerged,accompanied with changes in various cell types including neurons,indicative of the second round of attacks.By day-38,major cell types are still substantially deviated from uninjured states,demonstrating prolonged alterations.This study provides a comprehensive mapping of cellular/molecular pathological changes along the temporal axis after SCI,which may facilitate the development of novel therapeutic strategies,including those targeting microglia. | Chen Li Zhourui Wu Liqiang Zhou Jingliang Shao Xiao Hu Wei Xu Yilong Ren Xingfei Zhu Weihong Ge Kunshan Zhang Jiping Liu Runzhi Huang Jing Yu Dandan Luo Xuejiao Yang Wenmin Zhu Rongrong Zhu Changhong Zheng Yi Eve Sun Liming Cheng | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 4 |
| 4 | Computational studies on the seismic response of the State Route 99 bridge in Seattle with SMA/ECC plastic hinges显示文摘This paper reports a computational study on the seismic response of a three-span highway bridge system incorporating conventional and novel substructure details for improved seismic performance.The bridge has three continuous spans supported by two single-column piers and integral abutments founded on drilled shafts.It will be the first full-scale highway bridge to use superelastic shape memory alloy bars (SMA)and engineered cementitious composite (ECC)to mitigate column plastic hinge damage and minimize residual displacements after a strong earthquake. A three-dimensional computational model capturing the nonlinear constitutive response of the novel materials and the effects of dynamic soil-structure interaction was developed to assess the seismic response of the bridge in finite-element software OpenSees.Two versions of the same bridge were analyzed and compared,one with conventional cast-in-place reinforced concrete columns,and the other with top plastic hinges incorporating Nickel-Titanium (NiTi)SMA reinforcing bars and ECC.The novel SMA/ECC plastic hinges were found to substantially reduce damage and post-earthquake residual displacements in the bridge substructure,but led to larger maximum drifts relative to the bridge with conventional reinforced concrete plastic hinges.The analysis results suggested that the novel plastic hinges could lead to improved post-earthquake serviceability of bridges after intense earthquakes. | Jiping GE M.Saiid SAIIDI Sebastian VARELA | 2019 | Frontiers of Structural and Civil Engineering2019，13，1： | 3 |

| 6 | Seismic performance of precast bridge columns connected with grouted corrugated-metal duct through biaxial quasi-static experiment and modeling显示文摘In this paper,the seismic behaviors of precast bridge columns connected with grouted corrugated-metal duct(GCMD)were investigated through the biaxial quasi-static experiment and numerical simulation.With a geometric scale ratio of 1:5,five specimens were fabricated,including four precast bridge columns connected with GCMD and one cast-in-place(CIP)bridge column.A finite element analysis model was also established by using OpenSees and was then calibrated by using the experimental results for parameter analysis.The results show the biaxial seismic performance of the precast bridge columns connected with GCMD was similar to the CIP bridge columns regarding ultimate bearing capacity and hysteresis energy,and further,that it could meet the design goal of equivalent performance.The seismic performance of the precast bridge columns connected with GCMD deteriorated more significantly under bi-directional load than under uni-directional load.A proper slenderness ratio(e.g.,7.0-10.0)and longitudinal reinforcement ratio could significantly improve the energy dissipation capacity and deformation capacity of the precast bridge columns,while the axial load ratio and concrete strength had little influence on the above properties.The research results could bring insights to the development of the seismic design of precast bridge columns connected with GCMD. | Xia Zhanghua Lin Shangshun He Yongbo Ge Jiping Sun Jinlei | 2021 | Earthquake Engineering and Engineering Vibration2021，20，3： | 3 |
| 7 | Optimization of shearer sliding boots by plasma cladding with Cr_4MnTi显示文摘Severe production conditions in coal mines cause damage and failure problems with the oriented sliding boots of the mechanical shearer. Wear has been an especially vexing problem. Plasma cladding methods were used to study optimized sliding boot design. By cladding the substrate steel the surface may be made of a material more resistant to wear. The iron based alloy Cr4MnTi was coated onto a modified 45 steel matrix material in these tests. The results show that the alloy cladding layer is high strength, has high hardness, and is highly resistant to wear. After hardening and tempering, 45 steel substrate has great tenacity so the combined structure meets the performance requirements for the construction of shearer sliding boots. | Liu Hongtao Wang Luping Ge Shirong Cao Shoufan Jin Jing Gao Jiping | 2011 | Mining Science and Technology2011，21，6： | 2 |
