Abstract

Steel reinforcement is well known as an important component in forming building structures. However, as the community's need for reinforcing steel is increasing, the main material for forming steel reinforcement is decreasing so that the price is getting higher. The alternative that is suggested as a substitute for tensile steel reinforcement which is economical and easy to get is bamboo. The purpose of this study was to determine the ratio of beam bending using circular and square bamboo reinforcement and to determine the bending load that can be accepted by circular and square bamboo reinforcement. In this study an experimental method was used by conducting a series of tests ranging from preserving bamboo and testing aggregates as a building block for concrete. The cross sections of bamboo reinforcement used are square and circle shapes with a diameter of 10mm with beam dimensions of 900 mm x 150 mm x 150 mm. The results showed that the flexural strength produced by steel reinforcing concrete beam was 11,36 MPa, circular cross section bamboo reinforcing beam 8,73 MPa and rectangle cross section bamboo reinforcing concrete beam of 9,04 MPa.

Abstract

Perencanaan struktur bangunan tahan gempa sangat penting di Indonesia. Kabupaten Tana Toraja termasuk KDS-D dengan kategori resiko I dalam kelas situs SD. Sehingga metode Sistem Rangka Pemikul Momen Khusus (SRPMK) dapat digunakan dalam perencanaan. Perencanaan struktur gedung ini menggunakan konsep desain kapasitas berupa kolom kuat balok lemah. saat terjadi gempa yang kuat dengan metode tersebut diharapkan gedung ini tidak mengalami keruntuhan total. Dalam perencanaan ini, bangunan yang direncanakan adalah bangunan fiktif 15 lantai menggunakan beton bertulang dengan panjang bangunan 40 m, lebar bangunan 14 m, tinggi 55.8 m dengan fungsi sebagai hotel. Perencanaan dan perhitungan struktur gedung ini ditinjau terhadap beban mati, beban hidup, dan beban gempa. Perhitungan beban mati dan beban hidup mengikuti persyaratan SNI 1727-2013, dan beban gempa dianalisis secara statik dan dinamis mengikuti persyaratan SNI 1726-2012. Untuk analisa struktur bangunan digunakan aplikasi SAP2000V21. Hasil analisis dan desain menunjukkan dimensi balok dan kolom telah memenuhi kriteria penampang untuk SRPMK, dimana syarat “strong column weak beam” telah terpenuhi.

Abstract

The method used in this study is an experimental method by conducting a series of tests ranging from bamboo preservation, bamboo lamination and aggregate testing. The design of concrete mix design uses the SK SNI 03-2834 - 2000 method. The dimensions of the beam used are 900 mm long, 100 mm wide, and 150 mm high. Variations in the shape of the bamboo reinforcement used are square and circle diameter of 10 mm.The results showed that the flexural strength produced by steel reinforcing concrete blocks was 842.4253 Kgm, square laminated bamboo reinforcement concrete blocks amounted to 546.7123 Kgm, and circular laminated bamboo reinforcement concrete blocks amounted to 536.5153 Kgm. The percentage of average flexural strength of laminated bamboo reinforcement is equivalent to 60% of steel reinforcement.

Abstract

This study aims to examine the flexural capacity of bamboo beams through a lamination process using glue. The lamination process is intended to increase the strength and stability of bamboo beams so that they can be used as alternative building materials. In this study, samples of bamboo beams were processed using the lamination method and tested to measure their flexural capacity. The experimental results showed that the largest flexural strength of laminated petung bamboo beams was sample 2 with a value of 124.6312 kg/cm2, while the lowest was sample 3 with a value of 101.2629 kg/cm2, and an average flexural strength with a value of 114 ,2453kg/cm2. From the results obtained, according to PKKI wood laminated petung bamboo for strong class construction, the flexural strength of laminated petung bamboo beams is classified as strong class IV.
