Abstract

fetched live from OpenAlex

Penelitian ini bertujuan untuk mengetahui perbandingan kebutuhan material baja pada kuda-kuda bentuk Pratt truss, Howe Truss, danCompound Fan Truss sehingga dapat diketahui jumlah penggunaan kebutuhan material baja terkecil. Penelitian ini akan membandingkantiga tipe kuda-kuda pada panjang bentangan 24 m. Perhitungan gaya batang pada kuda-kuda menggunakanprogram SAP 2000 yang didasarkan oleh beban mati, beban hidup, dan beban angin yang bekerja pada struktur kuda-kuda sesuai denganSNI-03-1727-1989 tentang Tata Cara Pembebanan Untuk Rumah dan Gedung. Data perhitungan gaya batang didapat, selanjutnya ditentukanjenis profil baja yang sesuai dengan besarnya gaya dan jenis batang yang berkerja yaitu batang tarik dan tekan. Perhitungan dimensi profilpada batang kuda-kuda dilakukan sesuai dengan SNI 03-1729-2002 tentang Tata Cara Perencanaan Struktur Baja Untuk BangunanGedung.Berat parameter profil di setiap batang kemudian dikalikan dengan panjangnya sehingga diketahui volume material baja yang diperlukan dalam satuan kilogram(kg). Volume seluruh batang dijumlahkan dan kemudian dibandingkan dengan bentuk kuda-kudayang lainnya.Perbandingan dilakukan untuk mendapatkan bentuk kuda-kuda yang paling sedikit menggunakan bahan material baja.Kesimpulan penelitian ini adalah pada bentang 24 m bentuk kuda-kuda Compound Fan Truss memiliki jumlah kebutuhan materialbaja terkecil yaitu sebesar 1220,51 kg. Kuda-kuda Howe Truss memiliki jumlah kebutuhan pemakaian material baja dengan nilai sebesar1870,12 kg, sedangkan kuda-kuda Bentuk Pratt Truss memiliki jumlah kebutuhan material baja terbesar pada bentang ini yaitu 2112,37 kg.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
