By using the theoretical and nonlinear static (pushover) analyses, the seismic performances of three types of CFST-Y piers were evaluated at different seismic hazard levels. The theoretical formulas were first proposed to estimate the lateral stiffnesses for piers with different pier\u2013deck connections. Then, the structural ductility with the development of plastic hinges in piers was investigated based on the pushover analyses. The results demonstrate that the structural dimensions, deck mass, shear limit, and stiffness of bearings can remarkably affect the formation of hinges and thereby lead to different energy dissipation patterns to achieve the expected performance in piers. The findings suggest an economic design strategy of piers, using CFST-Y members as energy dissipation fuses with multiple hinges, to achieve low-level seismic performance cost-effectively.<\/jats:p>","DOI":"10.3390\/sym14112371","type":"journal-article","created":{"date-parts":[[2022,11,10]],"date-time":"2022-11-10T19:18:29Z","timestamp":1668107909000},"page":"2371","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Energy Dissipation Enhanced by Multiple Hinges in Bridge Piers with CFST Y-Shaped Fuses"],"prefix":"10.3390","volume":"14","author":[{"given":"Qunfeng","family":"Liu","sequence":"first","affiliation":[{"name":"School of Architecture and Civil Engineering, Xi\u2019an University of Science and Technology, Xi\u2019an 710054, China"},{"name":"State Key Laboratory for Strength and Vibration of Mechanical Structures, School of Aerospace Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhaoyang","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Architecture and Civil Engineering, Xi\u2019an University of Science and Technology, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xing","family":"Wu","sequence":"additional","affiliation":[{"name":"CCCC First Highway Consultants Co., Ltd., Xi\u2019an 710068, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaile","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Architecture and Civil Engineering, Xi\u2019an University of Science and Technology, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiang","family":"Ren","sequence":"additional","affiliation":[{"name":"School of Architecture and Civil Engineering, Xi\u2019an University of Science and Technology, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jialong","family":"Xiao","sequence":"additional","affiliation":[{"name":"School of Architecture and Civil Engineering, Xi\u2019an University of Science and Technology, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1061\/(ASCE)1076-0431(1997)3:1(3)","article-title":"Aesthetic considerations for urban pedestrian bridge design","volume":"3","author":"Yang","year":"1997","journal-title":"J.
