    A moment resistant beam end connection using energy dissipative couplers for precast concrete structures

    Full text link
    There is an increasing demand for precast reinforced concrete (RC) structures due to their undeniable advantages, such as rapid assembly, material standardization, and labor quality. The structural performance of precast RC structures depends not only on the quality of the precast members but also on joints and connections. In recent years, significant attention has been given to replaceable energy-dissipative devices for beam-to-column connections in precast RC structures. This paper proposes a novel moment-resisting energy-dissipative beam end connection in precast RC systems. The proposal is based on the results of intensive experimental and numerical studies conducted in the research project. The beam longitudinal reinforcements are connected to the joint using the developed fuse-type mechanical couplers (FTMCs) that have energy dissipation capability. While the bending moment in the connection is transformed into an axial force couple and transferred by FTMCs, the shear force is transmitted through the steel hinge at the center of the beam. The cyclic behavior of the proposed connection was experimentally investigated, resulting in a robust numerical model for the connection. The experiments demonstrated that the proper configuration of FTMCs in the connection enables reaching a 4% drift ratio without causing major damage to the RC beams. Macro models adopting pivot and kinematic hysteresis approaches for FTMCs were built in the numerical part. The pivot model reasonably and consistently predicted the experimental force-displacement relations of the proposed connections. The ability of the pivot model to estimate the energy dissipation capacities varies almost 6 similar to 16%.Scientific and Technological Research Council of Turkey (TUBITAK) [TEYDEP 5190016]This work was supported by the Scientific and Technological Research Council of Turkey (TUBITAK) (Grant Number: TEYDEP 5190016)

    Weight’s impact on life’s quality: A comparative study of emotional appetite and psychological health across BMI categories

    Full text link
    This study examined the relationship between the impact of weight on quality of life (QoL), emotional appetite, and psychological well-being. The study included 124 individuals with obesity with a body mass index (BMI) of more than 30 kg/m2, 129 individuals with overweight with a BMI between 25 and 29.9 kg/m2, and 123 normal-weight individuals with a BMI less than 25 kg/m2 who applied to certain nutrition and dietetics clinics in Istanbul. We administered the Impact of Weight on Quality of Life Scale (IWQOL), Emotional Appetite Questionnaire (EAQ), and Psychological Well-Being Scale (PWS) to the individuals. The QoL and psychological well-being scores in the group with a normal BMI showed a strong positive association. Positive emotional appetite ratings, psychological well-being, and QoL showed a noteworthy positive link in the BMI group with overweight. The study revealed a negative relationship between a bad emotional appetite and psychological well-being. The QoL and psychological well-being scores in the BMI group with obesity showed a strong positive association. In addition, the psychological well-being scores of those in the normal and overweight BMI groups were significantly higher than those in the BMI group with obesity. The negative emotional appetite scores in the BMI groups with obesity and overweight were significantly higher than those in the normal BMI group. Those in the normal BMI group had significantly higher positive emotional appetite scores than those in the BMI group with overweight did. Findings indicate significant associations between BMI, QoL, and psychological well-being, with potential interventions identified to enhance patient care and support. These results underscore the critical role of social work in addressing weight-related psychological and emotional challenges within health care settings. © 2025 Taylor & Francis Group, LLC

    Ecocritical Reflections: Post-Anthropocentrism in Bilge Karasu's The Prey

    Full text link
    In his attempt to critique anthropocentrism and speciesism, Bilge Karasu, a postmodern Turkish writer, problematizes the relationship between human and nonhuman entities. In The Prey, one of the short stories in The Garden of Departed Cats (2003), Karasu employs surrealist and unnatural narrativity to disrupt the mimetic illusion considered by many posthumanist scholars as essential for the formation of new subjectivities. Through a narrative rich in figurative language and metafictional elements, Karasu engages with the complexities of species hierarchy, power relations and the redefinition of love. Surrealistically, set against the backdrop of variable weather conditions, the story questions human superiority over nature, highlighting the vulnerability and interdependence of all beings. Initially viewing the fish as a burden, the fisherman's journey parallels his childhood memory of encountering a snake, leading to a profound realization of the fish's capacity for affection and suffering. As empathy grows, so does the fisherman's ability to comprehend the language of the animal, culminating in a physical and spiritual metamorphosis upon their union. Through exploration of human cruelty and the possibility of harmony with nonhuman animals, the story highlights and subtly critiques the nature of humanity. Thus, by depicting a unification between human and nonhuman, The Prey suggests that genuine humanity lies in embracing interconnectedness and fostering equality-based relationships with the animal other

    Alois Riegl's Values Theory and Prison Buildings in Turkey

    Full text link
    In Vienna at the beginning of the 20th century, when different debates on modernity were taking place, the art historian Alois Riegl made an important contribution to conservation studies with his 1903 article The Cult of the Modern Monument: Its Nature and Origin, published in 1903. The oscillation of modernity between the understanding of creating a system based on rationality brought about by the Enlightenment and the understanding of accepting the modernization process with all its complexity and contradictions seems to have influenced Riegl's approach in the field of conservation. Riegl tried to reconcile this dual understanding inherent in modernity. In this study, within the framework of Riegl's values theory, it is analyzed which values came to the forefront and which conservation processes were realized in the seven re-functionalized prison buildings (Yedikule Dungeons, Sinop Castle Prison, French Prison, Old Dat4a Prison, British Outpost, Sultanahmet Prison and Ulucanlar Prison) in Turkey. In the analyzed examples, it has been concluded that Riegl's commemorative value comes to the forefront, but other values should also be activated in the conservation process of a building. In the future conservation processes of the 378 abandoned prison buildings in Turkey, it is suggested to take into consideration the values theory, which will be important in terms of both the place of the buildings in collective memory and the continuity of their physical structures

    Enhancing 3D-Printed PP-CF parts: A novel resin-filling technique for mechanical property optimization

    Full text link
    This study investigates a novel post-processing technique aimed at enhancing the mechanical properties of 3D-printed polypropylene-carbon fiber (PP-CF) composite parts. The method involves printing components with internal voids to reduce weight and printing time, subsequently filling these voids with a low-cost resin known for its superior mechanical properties. Through systematic experimentation varying infill density and pattern, key quantitative findings were obtained. Tensile strength generally increased with higher infill density, reaching a maximum of 55.664 MPa for the resin-filled triangle infill pattern with 60% infill density. Impact energy showed a decreasing trend with increasing infill density, with the highest impact energy of 0.5 J recorded for the resin-filled triangle infill pattern with 60% infill density. Microstructural analysis revealed that the triangle infill pattern at 60% infill density exhibited the most effective resin penetration, contributing to superior mechanical performance. These findings emphasize the importance of infill pattern selection in resin distribution and mechanical enhancement in 3D-printed composite materials
