Abstract

Reinforced concrete beams in this study are designed precast in site or cast before being installed in position. This beam is made only by casting the beam reduced by the thickness of the plate and without the top reinforcement, while the lower reinforcement and shear reinforcement is still installed as required from the analysis. The goal is to shorten the working time and get better concrete quality. This beam is part of the structural elements of a building that has been designed and analyzed in advance with a computer program based on structural analysis, SAP2000 v.16. Dimensions and reinforcement requirements from the results of the structural analysis are used as references to analyze precast in site beams. Main beam dimensions resulting from building structure analysis are B1, B2, and B3 with dimensions of 300x500 mm, but with different amounts of reinforcement requirements. Meanwhile, the joist (BA) has dimensions of 250x400 mm. Then the precast in site beams B1, B2, and B3 have dimensions of 300x350 mm and joists (BA) have dimensions of 250x250 mm after deducting the plate thickness of 150 mm. After being cast and dried at the planned age, the beam is then lifted and positioned on the column provided, after which the upper reinforcement and slab reinforcement are installed and cast again. Analysis of lifting or erection is also carried out to ensure that the working load does not exceed its capacity. The analysis results show that the precast beam is able to carry all the working loads and the precast in site system can be applied safely.

Abstract

Struktur bangunan tahan gempa didasari oleh perencanaan yang baik dan sesuai dengan regulasi yang ada. Gedung sekolah termasuk salah satu bangunan yang termasuk dalam kategori IV dalam kategori risiko bangunan SNI 1726:2012. Karena alasan tersebut, gedung sekolah harus memiliki struktur yang kuat dan tahan gempa. Untuk mengetahui perilaku struktur terhadap gempa perlu dilakukan analisis. Pada penelitian ini dilakukan analisis menggunakan gempa rencana dengan analisis respons spektrum pada studi kasus Gedung Ruang Kelas SMAN 9 Denpasar. Permodelan dan analisa akan dilakukan dengan bantuan perangkat lunak SAP2000. Data-data yang diperlukan dalam melakukan penelitian ini adalah data sekunder berupa as-built drawing serta data respon spektra pada lokasi studi kasus. Data ini didapatkan di situs Desain Spektra Indonesia lalu diinput pada program SAP2000 untuk dianalisis. Simpangan yang diperoleh dengan metode Respon Spektrum dengan menggunakan gempa rencana masih dibawah angka simpangan ijin. Didapatkan gaya geser maksimum arah x sebesar 927,43 kN, dan arah y sebesar 913,88 kN.
