The radially foldable bar structure is strengthened by the lower cable-strut system to obtain a higher structural stiffness. Then the comparison of the static behavior between the retractable suspen-domes and their corresponding foldable bar shell with quadrangular mesh is discussed. Moreover, the effects of different structural and geometric parameters, such as the rise-to-span ratio, the cross-section area of beams, cables and struts, and the pre-stress level of the lower cable-strut system, on the nodal displacements and member forces are investigated systematically. The results show that higher structural stiffness is anticipated with the introduction of cable-strut systems into the hybrid structure. When the rise-to-span ratio is equal to 0.2, the maximal nodal displacement of the suspen-dome reaches the minimal value. The increase of the cross-section area of steel beams contributes an enormous amount to the structural stiffness. Increasing cable and strut sections has little impact on the mechanical behavior of suspen-domes. Moreover, the prestress level of cable-strut systems has a slight influence on the nodal displacements and member forces. Parametric analysis can be regarded as an essential basis for the optimization of the design of a retractable suspen-dome structure.<\/jats:p>","DOI":"10.3390\/sym13071105","type":"journal-article","created":{"date-parts":[[2021,6,22]],"date-time":"2021-06-22T22:10:59Z","timestamp":1624399859000},"page":"1105","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Static Behavior of a Retractable Suspen-Dome Structure"],"prefix":"10.3390","volume":"13","author":[{"given":"Xuhong","family":"Shen","sequence":"first","affiliation":[{"name":"National Prestress Engineering Research Center, Key Laboratory of C & PC Structures of Ministry of Education Southeast University, Nanjing 210096, China"},{"name":"China Design Group Co., Ltd., Nanjing 210001, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9784-5787","authenticated-orcid":false,"given":"Qian","family":"Zhang","sequence":"additional","affiliation":[{"name":"National Prestress Engineering Research Center, Key Laboratory of C & PC Structures of Ministry of Education Southeast University, Nanjing 210096, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7572-7912","authenticated-orcid":false,"given":"Daniel Sang-Hoon","family":"Lee","sequence":"additional","affiliation":[{"name":"The Royal Danish Academy, Schools of Architecture, Design and Conservation, 1435 Copenhagen, Denmark"}]},{"given":"Jianguo","family":"Cai","sequence":"additional","affiliation":[{"name":"National Prestress Engineering Research Center, Key Laboratory of C & PC Structures of Ministry of Education Southeast University, Nanjing 210096, China"}]},{"given":"Jian","family":"Feng","sequence":"additional","affiliation":[{"name":"National Prestress Engineering Research Center, Key Laboratory of C & PC Structures of Ministry of Education Southeast University, Nanjing 210096, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"136","DOI":"10.1016\/j.jcsr.2015.07.016","article-title":"Postbuckling behavior of flexibly connected single layer steel domes","volume":"114","author":"Ramalingam","year":"2015","journal-title":"J.
