    Experimental setup for beams with adjustable rotational stiffness: An educational perspective
    (Wiley, 2021-11-17) Türker, Hakan Tacattin; Sağıroğlu, Serkan; Deliktaş, Babür; TÜRKER, HAKAN TACATTİN; SAĞIROĞLU, SERKAN; DELİKTAŞ, BABÜR; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/İnşaat Mühendisliği Bölümü,; 0000-0001-5820-0257; 0000-0002-4035-4642; A-4984-2018; AAH-8687-2021; AAH-8862-2021
    In structural analysis, the rotations of beams' supports are considered either completely fixed or completely free. Therefore, supports are idealized as fixed, pinned (hinged), or roller. In real structures, regarding rotation, the support behavior is neither fully rigid nor completely free and shows a semi-rigid behavior in most cases. In this study, an educational test setup was created for a beam with semi-rigid supports to examine the effect of semi-rigid support on structural behavior. In this experimental setup, support conditions with different rotational stiffness can be obtained from pinned support to fixed support, which can be easily changed between the pinned and the fixed support. The physical equivalent of the rotational stiffness concept is shown in an easy and understandable way with the theoretical equations. A simulation tool based on the derived analytical equation is also developed using Mathematica Software. The simulation tool provides the users with a way to visualize the deformation of the system. The results of beam tests with different support conditions were compared with the results of the simulation, and the effects of semi-rigid support on the beam behavior were shown. The results revealed that the semi-rigid supported beam assembly created can also be used to examine the behavior of frame beams under vertical load. These simple novel experimental setup and simulation tools provided are convenient and useful approaches to demonstrate the structural concepts, including the semi-rigid support and behavior of beams in a frame structure.

    Stochastic approach on safe designing of double layer grid space structure against member length imperfections
    (Korean Soc Steel Construction-KSSC, 2021-01-29) Türker, Hakan T.; TÜRKER, HAKAN TACATTİN; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/İnşaat Mühendisliği Bölümü.; 0000-0001-5820-0257; A-4984-2018
    The imperfections in Double Layer Grid Space Structure (DLGSS) threaten the safety of designs. The imperfections in the member length of DLGSS may result from human-based causes such as manual cuts, tolerance sensitivity in CNC cuttings and variation in temperature. Therefore, analyzing the impacts of imperfections is vital to ensure the safety of DLGSS systems. Thus, a safe design of DLGSS against member length imperfections is the main focus of this paper. A novel and practical safe design approach, which considers member length imperfections, has been proposed based on linear elastic and probabilistic analyses methods. The impacts of member length imperfections on the DLGSS behavior were also evaluated in detail. Variation in positions of imperfect members, initial size of length imperfections (longer or shorter than the ideal size) and number of imperfect members were selected as the parameters to be analyzed. A 3D computer program, which considers the initial length imperfections of members, has been codded to analyze the space trusses. The impact of imperfection on a space structure was investigated by repeating the simulations for stochastic dispersion of imperfect member position and initial member length imperfection. The results revealed that initial length imperfection might have a considerable impact on the DLGSS behavior. The DLGSS systems can safely be designed by employing the proposed design approach to overcome the defined imperfections.
