Author: Edi Supriyanto Email: edisupriyanto@gmail.com Website: https://neurostruct.id/ Consultation: https://wa.me/6281338718071/ Part I: English Version (Academic Paper) Abstract Reinforced concrete beams are primary structural members that transfer floor and roof loads to columns. The efficacy of a building's superstructure relies heavily on the correct selection and design of beam types. This paper provides a comprehensive analysis of various beam typologies, including simply supported beams, cantilever beams, continuous beams, and flanged (T and L) beams. We integrate mathematical models for bending moment calculation and shear analysis to provide a technical baseline for structural engineers. 1. Introduction The structural integrity of a building is inextricably linked to the performance of its flexural members. In Bali, where seismic activity is prevalent, the selection of beam types must account for both gravity loads and lateral seismic forces. This article categorizes beams based on their static indeterminacy and cross-sectional geometry. 2. Typological Classification and Mathematical Analysis 2.1 Simply Supported Beams These beams are supported at both ends. The maximum bending moment ($M_{max}$) for a simply supported beam under uniform load ($w$) with span ($L$) is: $$M_{max} = \frac{w \cdot L^{2}}{8}$$ 2.2 Cantilever Beams Fixed at one end and free at the other, these beams are susceptible to significant deflection. The moment at the support is: $$M_{support} = \frac{w \cdot L^{2}}{2}$$ 2.3 Continuous Beams Continuous beams span over multiple supports, which redistributes moments and increases structural efficiency. The calculation of moments requires the three-moment equation or stiffness matrix methods to determine the negative moment at supports ($M_{s}$) and positive moment at mid-span ($M_{m}$). 2.4 Flanged Beams (T-Beams and L-Beams) These are monolithic with the slab, enhancing stiffness. The effective flange width ($b_{e}$) is a critical parameter: $$b_{e} \le \frac{L}{4}$$ $$b_{e} \le b_{w} + 16 \cdot h_{f}$$ Where: $b_{w}$ = Web width $h_{f}$ = Flange thickness 3. Conclusion Engineers must meticulously select beam types based on span length, architectural requirements, and seismic demand. Standardized design protocols are essential for ensuring longevity and safety. Part II: Indonesian Version (Versi Bahasa Indonesia) Abstrak Balok beton bertulang adalah elemen struktural utama yang menyalurkan beban lantai dan atap ke kolom. Efektivitas struktur atas bangunan sangat bergantung pada pemilihan dan desain tipe balok yang tepat. Makalah ini memberikan analisis komprehensif mengenai berbagai tipologi balok, termasuk balok sederhana, balok kantilever, balok menerus, dan balok flens (T dan L). Kami mengintegrasikan model matematis untuk perhitungan momen lentur dan analisis geser sebagai dasar teknis bagi insinyur struktur. 1. Pendahuluan Integritas struktural bangunan tidak terlepas dari kinerja elemen lenturnya. Di Bali, di mana aktivitas seismik lazim terjadi, pemilihan tipe balok harus memperhitungkan beban gravitasi dan gaya seismik lateral. Artikel ini mengategorikan balok berdasarkan ketidaktentuan statis dan geometri penampangnya. 2. Klasifikasi Tipologi dan Analisis Matematis 2.1 Balok Sederhana (Simply Supported) Balok ini didukung di kedua ujungnya. Momen lentur maksimum ($M_{max}$) untuk balok sederhana dengan beban merata ($w$) dan bentang ($L$) adalah: $$M_{max} = \frac{w \cdot L^{2}}{8}$$ 2.2 Balok Kantilever Terjepit di satu ujung dan bebas di ujung lainnya, balok ini rentan terhadap defleksi yang signifikan. Momen pada tumpuan adalah: $$M_{support} = \frac{w \cdot L^{2}}{2}$$ 2.3 Balok Menerus (Continuous Beams) Balok menerus membentang melewati beberapa tumpuan, yang mendistribusikan ulang momen dan meningkatkan efisiensi struktural. Perhitungan momen memerlukan metode persamaan tiga momen atau matriks kekakuan untuk menentukan momen negatif di tumpuan ($M_{s}$) dan momen positif di tengah bentang ($M_{m}$). 2.4 Balok Flens (Balok T dan Balok L) Balok ini menyatu secara monolit dengan pelat, sehingga meningkatkan kekakuan. Lebar flens efektif ($b_{e}$) adalah parameter kritis: $$b_{e} \le \frac{L}{4}$$ $$b_{e} \le b_{w} + 16 \cdot h_{f}$$ Dimana: $b_{w}$ = Lebar badan balok $h_{f}$ = Tebal pelat (flens) 3. Kesimpulan Insinyur harus memilih tipe balok secara cermat berdasarkan panjang bentang, kebutuhan arsitektural, dan beban seismik. Protokol desain standar sangat penting untuk memastikan keawetan dan keamanan bangunan.
