Analisa Kekuatan Struktur Bambu Pada Pembangunan Entry Building Green School Ubud

Abstract

Bamboo has 1.000-4.000 kg/cm2 tensile strength, so it becomes a substitute for reinforced concrete steel reinforcement. Makes bamboo has the potential to continue to be developed as a construction material not only for simple buildings but for more complex buildings. The elastic nature of bamboo, the bamboo structure has a high resistance to both wind and earthquake, where the MOE (Modulus of Elasticity) of 178.758 kg/cm2, MOR (Modulus of Rupture) of 886 kg/cm2, and compressive strength of 347 kg of fiber parallel on cm2. Analysis using SNI 1727-2013 for loading, SNI 1726-2012 for earthquake loading. Modeling and analysis of internal forces on structures using the software Sap2000 ver.15. The results of the upper structure of the dimensions of the bamboo frame diameter 120 mm and bamboo rafts diameter 80 mm. The superstructure on the bamboo column diameter 150 mm and bamboo beam diameter 150 mm. Planning bamboo plates with diameter 80 mm. Substructure with concrete material the size of the footing 0.8 m x 0.8 m and 1.2 m x 1.2 m for anchor planning using bolt dimensions 12.7 mm with the number of bolts as many as two pieces.Bambu memiliki kekuatan Tarik sebesar 1.000-4.000 kg/cm2 atau setara dengan besi baja kualitas sedang sehingga dapat menjadi pengganti tulangan baja beton bertulang. Hal ini membuat bambu memiliki potensi untuk terus dikembangkan sebagai material konstruksi bukan hanya untuk bangunan yang sederhana namun untuk bangunan yang lebih kompleks. Sifat bambu yang elastis, struktur bambu mempunyai ketahanan yang tinggi baik terhadap angin maupun gempa, dimana MOE (Modulus of Elasticity) sebesar 178,758 kg/cm2, MOR (Modulus of Rupture) sebesar 886 kg/cm2, dan kuat tekan sejajar serat sebesar 347 kg/cm2. Analisa dengan menggunakan SNI 1727-2013 untuk pembebanan, SNI 1726-2012 untuk pembebanan gempa. Pemodelan dan analisa gaya dalam pada struktur dengan bentuan software Sap2000 ver.15. Hasil upper struktur dimensi kuda–kuda bambu 120 mm diameter baut 15 mm sejumlah 1, usuk bambu diameter 80 mm, baut 8 mm berjumlah 1 buah. Super struktur pada kolom bambu berdiameter 150 mm dan balok bambu dengan diameter 150 mm menggunakan Perencanaan plat bambu dengan diameter 80 mm. Sub struktur dengan bahan beton ukuran pondasi telapak 0,8 m x 0,8 m dan 1,2 m x 1,2 m untuk perencanaan angkur menggunakan diemensi baut 12,7 mm dengan jumlah baut yaitu sebanyak 2 buah.

Prestressed beam system due to the addition of a long-span beam in building infrastructure

“…In designing prestressed concrete beams, there are several references used such as, SNI 2847:2019 [9] and SNI 7833:2012 [10] for concrete structure and prestressed concrete beam, the load used in design complies to SNI 1727:2020 [11] and related to anticipating earthquake hazards, one of which was SNI 1726:2019 Procedures for planning earthquake resistance for building and non-building structures located in earthquake-prone areas [12,13]. The analysis and design of prestressed beams are using ETABS'17 software.…”

Performance of the Pivot Hooks to Enhance the Flexural Capacity of Bamboo Reinforced Concrete Beams

“…Specifically discussing about bamboo, as a species of flora that massively grow in Indonesia (Putra, et al, 2020), this kind of plant is often be used in traditionally architectural component of custom houses in every part of Indonesia. Some people in specific regions use bamboo as structural components of the houses, such as its beam and columns.…”

Educational Tour of The Bamboo Village of Telagah With Ecological Architecture

“…As for the research conducted by I. N. Sinarta, namely calculating the mechanical properties of bamboo that is not preserved with bamboo that is preserved using borax, in his explanation bamboo that uses borax will certainly have more durability, both in terms of strength and durability of the bamboo itself [6]. From the characteristics, advantages, and disadvantages as well as the effect of bamboo preservation on the structure and durability of bamboo, the author wants to create a place that can make bamboo more useful, can be processed properly, and produce well-processed bamboo as well.…”
