Beginners and even experienced ones have difficulties in completing the structural fire analysis due to numerical difficulties such as convergence errors and singularity and have to spend a lot of time making many repetitive changes on the model. The aim of this article is to highlight the advantages of explicit solver which can eliminate the mentioned difficulties in finite element analysis containing highly nonlinear contacts, clearance between modeled parts at the beginning and large deflections because of high temperature. This article provides important information, especially for researchers and engineers who are new to structural fire analysis.

The finite element method is utilized to achieve mentioned purposes. First, a comparative study is conducted between implicit and explicit solvers by using Abaqus. Then, a validation process is carried out to illustrate the explicit process by using sequentially coupled heat transfer and structural analysis.

Explicit analysis offers an easier solution than implicit analysis for modeling multi-bolted connections under high temperatures. An optimum mesh density for bolted connections is presented to reflect the realistic structural behavior. Presented explicit process with the offered mesh density is used in the validation of an experimental study on multi-bolted splice connection under ISO 834 standard fire curve. A good agreement is achieved.

What makes the study valuable is that the points to be considered in the structural fire analysis are examined and it is a guide that future researchers can benefit from. This is especially true for modeling and analysis of multi-bolted connections in finite element software under high temperatures. The article can help to shorten and even eliminate the iterative debugging phases, which is a problematic and very time-consuming process for many researchers.

The importance and value of the leisure phenomenon are becoming more prominent daily as it becomes a determining indicator of both qualities of life and social welfare. The COVID-19 pandemic, which has caused severe disruptions in the lifestyles of individuals, has also made it inevitable to face the emergence of sociocultural conditions in which traditional daily life routines have disappeared and the reorganisation of the leisure space. In line with the conditions mentioned earlier, the characteristics of the ‘new’ and the ‘old’ have started to come together in the daily lives and leisure spaces of individuals in constant conflict. Under these conditions, individuals who spent their leisure time travelling from one place to another before the pandemic had to choose different leisure options. Therefore, the leisure space, which is an integral part of the social life of today's individual, has evolved into an unthinkable position independently of the COVID-19 pandemic effects. From this point of view, this study aims to examine the transformation of the leisure space due to the COVID-19 pandemic within the framework of previous studies on this subject and to discuss it in the context of sustainability. For this purpose, firstly, a general framework is drawn on the historical development of the leisure concept, and then its relationship with the COVID-19 pandemic is evaluated. In the last part of the study, the new forms of leisure that have emerged due to the process, as mentioned earlier, are discussed over the critical issues in ensuring the sustainability of leisure practices.

Social/physical distancing rules that resulted in the novel coronavirus (COVID-19) have caused restrictions on national and international transportation. Since tourism activities are an industry based on transportation and travel, they have been affected negatively because of COVID-19. It has become necessary to create a contactless environment by leveraging technology to mitigate these negative impacts. smart transportation system (STS) applications have played a crucial role in enabling contact-free travel in providing the continuation of tourism activities in a controlled manner by utilizing information and communication technologies. Therefore, in this study, it was tried to determine whether STS applications are functional in ensuring the contactless transportation required in COVID-19 and in the face of possible future outbreaks. In this study, COVID-19 and STS terms are tried to be defined, and the importance of these two concepts in terms of tourism activities has been discussed considering their cause–effect relationship in line with the purpose of the research. STS applications have been determined to be the most appropriate approach in terms of carrying out controlled tourism activities in accordance with the social/physical distancing rules arising from COVID-19. According to the findings of the research, STS provides an opportunity for people to use contactless payments and purchase tickets online with smart phones. Additively, by controlling passengers’ luggage through mobile applications and reducing the time spent waiting in the lobby, thereby minimizing prolonged interpersonal contact.

Human life has been unfavourably impacted by COVID-19, which has impacted the entire planet. Contrastingly, it is now crucial to discern the significance of health in human life and pay more attention to protecting health. Owing to COVID-19's influence on lifestyle, it is evident that the pandemic contributes to the development of health tourism and that wellness tourism, which was in the pre-pandemic growth trend, is favoured more often. Therefore, it is indisputable that stakeholders in the health and tourism industries view the rising demand for health-focused holidays as a potential. However, on the opposite hand, it is meaningful to broaden the number of products made available within the context of wellness tourism, to pinpoint areas that are conducive to health-related activities, to generate the infrastructure and superstructure required in these areas and to step up marketing initiatives in order to make the most of this opportunity. To address these concerns, it is deemed crucial that the parties involved in the tourism and health sectors coordinate their efforts.
