Numerical Investigation of the Collapse of the Steel Truss Roof and a Probable Reason of Failure

Abstract

This study investigates the failure of a roof with steel truss construction of a factory building in Tekirdag in North-western part of Turkey. The failure occurred under hefty weather conditions including thunderbolt, lightning strikes, heavy rain and fierce winds. In order to interpret the reason for the failure, the effects of different combinations of factors on the design and dimensioning of the roof are checked. Therefore, finite element analysis is performed several times under different assumptions and considering different factors aiming to determine the dominant ones that are responsible for the failure. Each loading condition gives out a characteristic form of failure. The scenario with the most similar form of failure to the real collapse is considered as the most likely scenario of failure. Also, the factors included in this scenario are expected to be the responsible factors for the partial collapse of the steel truss structure.

Investigating the Use of an Artificial Intelligence Chatbot with General Chemistry Exam Questions

“…ChatGPT has been described as a “turning point for artificial intelligence” due to its convincing language capabilities that can produce text in response to open-ended questions that are comparable to good high school essays . Where an Internet search engine would provide a list of Internet links, ChatGPT can produce information in simple sentences and explain concepts in ways people can easily understand .…”

“…In the opinion piece “What Would Plato Say About ChatGPT?” Tufecki proposes that high schools and colleges are places where ChatGPT’s “most interesting and troubling aspects will become clear” . For some topics the author found ChatGPT’s responses to be cogent, well-reasoned, and clear, and because the system is interactive follow-up requests could lead to more details or changes.…”

“…Given student access to this technology, how should teachers use it? Tufecki suggests students could use ChatGPT as a tool to generate building blocks of an essay, similar to how students are allowed to use calculators or other mathematical resources in science courses. − Another approach is to assign a complicated topic and encourage students to use tools like ChatGPT as part of their research and, in the process, students would assess the veracity and reliability of AI generated content . This would be a very authentic task that parallels future applications of ChatGPT as chatbots will soon transform many occupations and an educational goal must be to help students use these resources for the betterment of humanity …”
