 Abstrak

[Sejak tahun 2003 diperkenalkan sebuah teori baru mengenai torsi yang disebut dengan modèle couplè dimana dalam teori tersebut dinyatakan momen torsi yang bekerja pada balok-tipis penampang terbuka (open cross-section thin-walled) berhubungan erat dengan bending momen sehingga menyebabkan penyimpangan sudut torsi dan shear center mengalami displacement searah sumbu horisontal. Teori ini membantah teori klasik VZ. Vlasov yang menyatakan tidak ada displacement pada shear center. Teori modèle couplè ini masih dikembangkan hingga tahun 2012 dengan pembuktian secara eksperimental dan numerik. Hasil pembuktian itu ternyata mendukung teori modèle couplè. Dari studi pustaka dan penelitian pendahuluan didapati beberapa kekurangan dalam prosedur eksperimental. Berdasarkan hal tersebut, maka dilakukan penelitian kembali dengan memperbaiki prosedur eksperimen sekaligus ingin membuktikan apakah hasil eksperimental sesuai dengan teori Vlasov atau teori modèle couplè. Analisis penelitian ini dilakukan dengan membandingkan hasil uji eksperimental, pemodelan numerik menggunakan software, prosedur analisis teori Vlasov untuk
balok-tipis, teori modèle couplè dan teori torsi yang umum.
Hasil penelitian ini memperlihatkan sudut torsi dan shear center analisis numerik sesuai dengan teori Vlasov sedangkan hasil uji eksperimental masih sama dengan hasil eksperimental terdahulu yang mendukung teori modèle couplè. Walau hasil uji eksperimental ini mendukung teori modèle couplè, bukan berarti teorema modèle couplè telah terbukti. Untuk itu disampaikan pula saran-saran perbaikan yang perlu dilakukan jika eksperimen serupa akan dilakukan kembali.
Since 2003 introduced a new theory called the torque modèle couple where the theory expressed in torsion moment acting on the open cross-section thin-walled are closely related to the bending moment causing deviation angle of torsion and shear center experienced displacement in the direction of the horizontal axis. This theory denies the classical theory VZ. Vlasov stating there is no displacement of
the shear center. Couple modèle theory is still being developed by 2012 with evidence experimentally and numerically. The results turned out to support the theory of proof modèle couple. From the literature study and preliminary research found several deficiencies in the experimental procedures. Based on this, the research conducted again by correcting the experimental procedure at the same time trying to prove whether
the experimental results according to Vlasov theory or theories modèle couple. The analysis is done by comparing the test results of experimental, numerical modeling using the software, the analysis procedure Vlasov theory for thinwalled, modèle couple theory and general theory of torque. The results of this study show the torque angle and shear center in accordance with the numerical analysis of Vlasov theory while the experimental test results are still the same as previous experimental results that support the theory modèle couple.
Although these experimental results support the theory test modèle couple, is not mean theorem has been proved. For it is also presented suggestions for improvement that need to be done if similar experiments will be performed again.;Since 2003 introduced a new theory called the torque modèle couple where the
