  • Current industrial practices and approaches are simplified and do not describe the actual behavior of plated elements of offshore topside structures for safety design due to fires. Therefore, it is better to make up for the defective methods with integrated fire safety design methods based on fire resistance characteristics such as residual strength capacity. This study numerically investigates the residual strength of steel stiffened panels exposed to hydrocarbon jet fire. A series of nonlinear finite element analyses (FEAs) were carried out with varying probabilistic selected exposures in terms of the jet fire location, side, area, and duration. These were used to assess the effects of exposed fire on the residual strength of a steel stiffened panel on a ship-shaped offshore structure. A probabilistic approach with a feasible fire location was used to determine credible fire scenarios in association with thermal structural responses. Heat transfer analysis was performed to obtain the steel temperature, and then the residual strength was obtained for the credible fire scenarios under compressive axial loading using nonlinear FEA code. The results were used to derive closed-form expressions to predict the residual strength of steel stiffened panels with various exposure to jet fire characteristics. The results could be used to assess the sustainability of structures at risk of exposure to fire accidents in offshore installations.

  • Purpose - The purpose of this paper is to explore the relationship between corporate social responsibility (CSR) and corporate present and future value. Design/methodology/approach - This paper intends to prove the relationship between CSR and corporate value once again by selecting A-share companies listed on the China Shenzhen Stock Exchange and Shanghai Stock Exchange from 2010 2017. This paper also examines the effect of five dimensions of CSR on corporate value in China. Findings - Empirical evidence shows that CSR is conducive to corporate value. The fulfillment of social responsibilities improves firm value in the future. Further, the regression results show that the social responsibility of the non-state-owned enterprise (Non-SOEs) group has a more significant effect on corporate financial performance than on the state-owned enterprise (SOEs) group. Research implications or Originality - This study has limitations. First, the grouping is only divided into two groups of SOEs and non-SOEs, and we did not consider foreign investments, that is, foreign-funded enterprises, for the comparative analysis. Second, only the linear relationship between CSR and corporate value was tested. In the future, we must determine whether there exists a nonlinear relationship between the two key concepts. Finally, there exists no research on CSR and corporate value by specific industries. Thus, the relationship between the five dimensions of CSR and corporate value should be investigated by specific industries.

  • The planning stage of laser scanning is crucial for acquiring high-quality 3D source data. It involves assessing the target space's environment and formulating an effective measurement strategy. However, existing practices often overlook on-site conditions, with decisions on scanner deployment and scanning locations relying heavily on the operators' experience. This approach has resulted in frequent modifications to scanning locations and diminished 3D data quality. Previous research has explored the selection of optimal scanner locations and conducted preliminary reviews through simulation, but these methods have significant drawbacks. They fail to consider scanner inaccuracies, do not support the use of multiple scanners, rely on less accurate 2D drawings, and require specialized knowledge in 3D modeling and programming. This study introduces an optimization technique for laser scanning planning using 3D simulation to address these issues. By evaluating the accuracy of scan data from various laser scanners and their positioning for scanning a retaining wall structure in a small-scale building, this method aids in refining the laser scanning plan. It enhances the decision-making process for end-users by ensuring data quality and reducing the need for plan adjustments during the planning phase.
