In this study, the motion response and connector load of a modular floating island in waves were numerically investigated based on potential flow theory. Numerical analysis was performed by adopting a Higher-order Boundary Element Method with the wave Green function. First, the motion response and connector loads of floating islands with different number of outer-module layers were studied. It was found that the single-layer island shows a significant advantage in terms of motion response and has a wider peak frequency range of the vertical load compared to the double-layers island. In addition, it was numerically confirmed that substantial horizontal connector loads can be induced by the horizontal motion responses associated with several dominant Eigen-modes of the floating island. Then, the effect of connector stiffness on the connector loads of the floating islands was also investigated. It was confirmed that the horizontal and vertical connector loads within the floating island can be reduced by adjusting the connector stiffness.</p></div>","PeriodicalId":596,"journal":{"name":"International Journal of Steel Structures","volume":"25 1","pages":"306 - 314"},"PeriodicalIF":1.1,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13296-025-00934-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to the SLR approach, the Preferred Reporting Items for Systematic Reviews and Meta-Analyse (PRISMA) was employed to report all protocols involved in this review work. Based on the review, the impact of fire on the lateral resistance and buckling performance of CFS can be classified according to the type of software, fire curves, numerical models, and design standards. However, the lateral resistance of steel is not a specific attribute that can be measured or evaluated directly from numerical modeling methods.

When a circular hollow section steel damper is placed in a building with stud supports, the stud supporting the damper is connected to the upper and lower beams. When an earthquake occurs, the shear force in the in-plane direction acts on the damper through the stud from the beam. However, depending on the three-dimensional behavior of the building and the arrangement of the damper and surrounding members, a load other than that in the in-plane direction might act on the damper. In this study, the mechanical characteristics of a circular hollow section steel damper in the external force direction were analyzed according to the cyclic load in the circumferential direction using finite element analysis. A reliable finite element analysis model was constructed based on the results of a previous study on unidirectional cyclic loading. The analysis results under cyclic loading conditions in circumferential directional cyclic loading were compared with those under unidirectional cyclic loading. The hysteresis curve resulted in a circular shape under circular directional loading. Moreover, the x- and y-direction load–displacement curves showed a similar strength-increasing ratio to unidirectional loading. Under circumferential directional loading, the strain was concentrated at the end of the welded part, similar to that under unidirectional loading. Furthermore, the strain was distributed in the circumferential directional loading, showing a smaller value than that of unidirectional loading.</p></div>","PeriodicalId":596,"journal":{"name":"International Journal of Steel Structures","volume":"25 1","pages":"111 - 124"},"PeriodicalIF":1.1,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through static analyses conducted under cyclic loading conditions, the influence of various geometric parameters on the mechanical characteristics and energy absorption capabilities of these dampers was investigated. The findings indicate that modifying the damper geometry can result in alterations of up to 6% in ultimate strength and up to 8% in yield strength. Also, the three-tube mesh model showed the highest yield strength among the different configurations that were studied.

Additionally, numerical analyses were performed to validate the design methodology incorporating prying force. The trial design results demonstrated that the slip capacity improved when the prying force was considered, especially in cases where the external force direction ranged between 27.6 and 90 degrees. The maximum observed improvement in slip capacity was a factor of 1.2. Moreover, the slip resistance of joints with thinner flanges was enhanced when prying force effects were accounted for. This increase in slip capacity due to prying force was further corroborated through fine element method (FEM) simulations.
