TY - JOUR TT - Stiffness Analysis of Knockdown Bookcases with Finite Element Method AU - Karaman, Abdurrahman PY - 2016 DA - December DO - 10.24011/barofd.238179 JF - Bartın Orman Fakültesi Dergisi PB - Bartın Üniversitesi WT - DergiPark SN - 1302-0943 SP - 9 EP - 19 VL - 18 IS - 2 KW - Demonte Tipi Kitaplık KW - Rijitlik KW - Sonlu Elemanlar Analizi N2 - In this study, in understatic load, the stiffness analysis of both wood base materials which are usedwith for demonte type bookshelves and the stiffness analysis of differentfasteners were investigated. Samples of the experiment particleboard (YL) andmedium density fiberboard (MDF) were used as wooden composites materials andtrapez connector with metal parts, metal minifix connector with metal peg,metal minifix connector with plastic peg, metal T connector, pipe typeconnector, and corner fitting were used joints. Knockdown bookcases wereexposed to static loading for six months by considering the critic loads whichcould effect while in service use. Bearing in mind the critic loads which mayaffect its usage, experimental samples were trialled under static loads. Threedimensional structure of the experimentalsamples were analysed an a computer byusing finite element method (FEM). Later, experimental data wascompared with the analysis data.According to the results ofexperiments, maximum compliance between ANSYS analysis results and the testresults of experiments terms of stiffness coefficient of the application wasobserved in the bookshelves which are made using particleboard trapezeconnector with 96.29%. at leastcompliance with metal 92.59% with metal minifix connector with metal pegcombination made using bookshelves.
