    Exploring the Factors Affecting Shared Biking Perception: Insights From Türkiye
    (Ege univ, fac economics & admin sciences, 2024-04-08) Oflaç, Bengü; Özcan, Seda; Sevil Oflac, Bengu
    Understanding consumer perception regarding shared biking services requires the analysis of psychological factors underlying the late diffusion of shared biking services. In this regard, by scrutinizing these underlying factors, we aim to uncover insights that can inform the development of targeted business strategies that better align with users' preferences and needs, thereby overcoming barriers to adoption and facilitating the wider dissemination of shared biking systems. Findings show that as consumers perceive shared biking services as useful and hedonic, their attitudes become more favorable. Importantly, highlighting the mediating role of compatibility, this study emphasizes the congruence among shared biking services, consumers' lifestyles, and their traveling habits. Findings also suggest that perceived complexity has a negative impact on shared biking attitudes. Interestingly, no significant relationship was found between perceived risk and shared biking attitude. The findings provide further support for innovation diffusion and theory of reasoned action. The suggested theoretical framework integrates variables related to both barriers and drivers, thus guiding future studies on the sharing economy. The study also provides insights that contribute to the development of service design and marketing strategies that respond better to users' needs, and also, facilitate the spread of these mobility systems.

    Strength Requirements for Shear Diaphragms Used for Stability Bracing of Steel Beams
    (Asce-Amer Soc Civil Engineers, 2017-04) Egilmez, O. Ozgur; Vardaroglu, Mustafa; Akbaba, Andac
    Light-gauge metal sheeting is often used in steel building and bridge industries as concrete deck formwork. Besides providing support to the fresh concrete, the sheeting acts as a shear diaphragm and provides continuous lateral bracing to the top flanges of the beams to which they are attached. An adequate stability-bracing system must possess sufficient stiffness and strength to control deformations and brace forces. Strength requirements for shear diaphragms are currently not well established. A computational study was conducted to develop strength requirements for shear diaphragms bracing simply supported steel beams. Both end-fastener and sidelap-fastener connections were modeled in the study. To the best of the authors' knowledge, this is the first study to quantify the stability-induced forces in sidelap fasteners. The effects of deck width and number of end and sidelap fasteners on brace forces were investigated. Expressions were developed to estimate the stability-induced brace forces in end-fastener and sidelap-fastener connections. (C) 2016 American Society of Civil Engineers.
