Abstract

Penelitian ini menjelaskan upaya untuk membandingkan studi analisis kapasitas torsi balok beton bertulang serat baja (SFRC) dengan desain modifikasi berbagai code (ACI 318-19; CSA A23.3:19, SNiP, dan Eurocode 2) serta menggunakan metode multi potensial kapasitas yang meliputi kegagalan interlock agregat. Delapan puluh lima spesimen diadopsi dari 16 kelompok studi sebelumnya, dan kekuatan torsi dibandingkan dengan menambahkan efek serat baja, meningkatkan kontribusi serat baja terhadap tulangan longitudinal dan transversal.
Setelah kapasitas torsi dari perumusan modifikasi diperoleh, dibandingkan kapasitas torsi eksperimental untuk menentukan akurasi prediksi kapasitas torsi yang mendekati hasil pengujian eksperimen. Kemampuan desain untuk memberikan prediksi yang akurat berdasarkan rasio kekuatan torsi yang dihitung, koefisien variasi (COV), dan uji distribusi data pada garis persamaan. Peraturan manakah yang memiliki prediksi kekuatan torsi yang paling mendekati dengan hasil uji eksperimental. Serta mengembangkan perumusan untuk perhitungan kapasitas torsi yang lebih optimal. Dari hasil yang disajikan, setiap prediksi desain torsi bervariasi secara signifikan. Membandingkan kelimanya menyimpulkan bahwa desain yang diperoleh menggunakan kode desain Eurocode 2 memberikan akurasi yang lebih baik dan berada pada sisi konservatif. Sedangkan kode desain lainnya menghasilkan kapasitas torsi yang berlebihan (overestimasi). Selain itu, analisis metode elemen hingga dilakukan untuk memvalidasi kapasitas torsi berdasarkan salah satu spesimen menggunakan software ABAQUS.

This study describes an attempt to compare torsional capacity analysis studies of steel fiber reinforced concrete beams (SFRC) with various design code modifications (ACI 318-19; CSA A23.3:19, SNiP, and Eurocode 2) as well as using a multi-capacity potential method which includes aggregate interlock failure. Eighty-five specimens were adopted from the previous 16 study groups, and the torsional strength was compared by adding the effect of steel fiber, increasing the contribution of steel fiber to the longitudinal and transverse reinforcement.
After the torque capacity of the modified formulation is obtained, it is compared to the experimental torque capacity to determine the accuracy of the torque capacity prediction, which is close to the experimental test results. Design capability to provide accurate predictions based on calculated torsional strength ratios, coefficient of variation (COV), and test data distribution on equation lines. Which regulation has the closest prediction of torsional strength to the experimental test results, As well as developing a formulation for a more optimal torque capacity calculation. From the results presented, each torque design prediction varies significantly. Comparing the five concluded that the design obtained using the Eurocode 2 design code provides better accuracy and is conservative. In comparison, other design codes result in an overestimation of torque capacity. In addition, using ABAQUS software, finite element method analysis was performed to validate the torque capacity based on one of the specimens.
