Thermal response of steel framing members in open car park fires

Xia YAN; Marion CHARLIER; Thomas GERNAY

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 9, Pages 1071-1088 doi: 10.1007/s11709-022-0879-0

Abstract: For open car park structures, adopting a performance-based structural fire design is often justified and allowed because the fire does not reach flashover. However, this design approach requires an accurate assessment of temperatures in structural members exposed to car fires. This paper describes a numerical study on the thermal exposure on steel framing members in open car park fires. Steel temperatures are computed by the coupling of computational fluid dynamics and finite element modeling, and by analytical models from the Eurocodes. In addition, the influence of galvanization on the steel temperature evolution is assessed. Results show that temperatures in unprotected beams and columns are influenced by the section geometry, car fire scenario, modeling approach, and use of galvanization. Galvanization slightly delays and reduces peak temperature. Regarding the different models, CFD-FEM (CFD: computational fluid dynamics, FEM: finite-element method) coupled models predict lower temperatures than the Hasemi model, because the latter conservatively assumes that the fire flame continuously touches the ceiling. Further, the Hasemi model cannot account for the effect of reduced emissivity from galvanization on the absorbed heat flux. Detailed temperature distributions obtained in the steel members can be used to complete efficient structural fire designs based on the member sections, structure layout, and use of galvanization.

Comparison of Production-Triggering Strategies for Manufacturing Enterprises under Random Orders Article

Longfei Zhou, Lin Zhang, Yajun Fang

Engineering 2021, Volume 7, Issue 6, Pages 798-806 doi: 10.1016/j.eng.2021.03.012

Abstract: In this paper, we focus on production-triggering strategies for manufacturing enterprises to satisfytime-triggered strategies, event-triggered strategies, and hybrid-triggered strategies.In each model, both part-production-triggering strategies and product-assembly-triggering strategiesThe results show that hybrid-triggered and time-triggered strategies yield faster order delivery andlower inventory costs than event-triggered strategies if the period is set appropriately.

Microplastics removal strategies: A step toward finding the solution

Frontiers of Environmental Science & Engineering 2022, Volume 16, Issue 1, Pages 7-7 doi: 10.1007/s11783-021-1441-3

Abstract:

Microplastics are an emerging threat and a big challenge for the environment. The presence of microplastics (MPs) in water is life-threatening to diverse organisms of aquatic ecosystems. Hence, the scientific community is exploring deeper to find treatment and removal options of MPs. Various physical, chemical and biological methods are researched for MPs removal, among which few have shown good efficiency in the laboratory. These methods also have a few limitations in environmental conditions. Other than finding a suitable method, the creation of legal restrictions at a governmental level by imposing policies against MPs is still a daunting task in many countries. This review is an effort to place all effectual MP removal methods in one document to compare the mechanisms, efficiency, advantages, and disadvantages and find the best solution.
