Coronavirus pandemic is the most catastrophic phenomena of nature. In a major disaster which affected substantially to human lifecycle and property loss. Instant rehabilitation for people with coronavirus was essential. As an immediate measure, it led application light-gauge steel within Saudi Arabia quick construction, in addition safety purposes during forthcoming. Several hospital buildings ...

Safety standards call for the separation of safety and nonsafety related systems. Although good guidance is provided in these standards on how to achieve the required hazard analysis, safety integrity assignment and validation to prove a safe system, there is little available on establishing safety boundaries around the critical components and the proof of isolation from non-safety functions. D...

Based on the structural viscoelastic boundary theory, considering geological changes of soil layer and depth tunnel crossing, dynamic time course analysis is carried out for defective lined tube sheet structure under non-uniform seismic excitation, to obtain force deformation law whole as well section. Analyze response shield non-consistent excitation influence misalignment factors, summarize i...

Information-theoretic complexity metrics, such as Surprisal (Hale, 2001; Levy, 2008) and Entropy Reduction 2003), are linking hypotheses that bridge theorized expectations about sentences observed processing difficulty in comprehension. These can be viewed syntactic derivations constrained by a grammar. However, this expectation-based view is not limited to information alone. The present study ...

this article presents the seismic vulnerability assessment of the s. joão de loure bridge, inportugal. the single span steel bridge has riveted joints, commonly affected by corrosion,which can lead to a significant stiffness reduction. with the objective of evaluating theinfluence of the joints stiffness in the structural response of the bridge, a structural model ofthe bridge was created, and ...

This paper deals with the assessment of Safety Management Systems performance and presents a new tool developed for that purpose. It recognizes two dimensions in a SMS: a structural facet corresponding to the formal description of the system and an operational one focused on the system’s influence on the working environment and practices of people. Building up the operational performance of a S...
