Studi Perbandingan Kapasitas Portal Beton Dinding Pengisi Bata Ringan Pengujian Laboratorium dan SAP 2000 terhadap Gaya Lateral

Abstract

Abstrak-Gempa merupakan fenomena alam akibat tektonik dan vulkanik. Risiko timbul antara lain kerusakan bangunan gedung, korban luka-luka, kematian dan kerusakan Infrastruktur lainnya. Beban gempa dalam Ilmu struktur disimulasikan menjadi Gaya Lateral dan Gaya Siklik sehingga mudah dalam permodelan. Pemilihan Bata Ringan sebagai dinding disinyalir dapat mengurangi berat sendiri (selfweight) struktur. System Application and Processing (SAP 2000) digunakan sebagai alat bantu menganalisis permodelan struktur bangunan terhadap beban-beban yang bekerja. Penelitian ini bertujuan untuk mengetahui perbandingan kapasitas tahanan beban dan simpangan hasil Laboratorium dengan aplikasi SAP 2000 terhadap Gaya Lateral. Pengujian dan Analisis Portal beton dengan dinding pengisi Bata Ringan berdimensi Lebar 1.00 m dan Tinggi 1.50 m dengan properti sebagai berikut pondasi 150/200 mm, kolom 150/150 mm, Balok 150/150 mm, tulangan pokok Ø10, tulangan sengkang Ø8 dan Dinding Bata Ringan AAC 60.20.10 cm. Pengujian portal beton pengisi bata ringan di laboratorium dan Analisis SAP 2000 menggunakan gaya lateral sebagai simulasi Gaya Gempa. Hasil pengujian laboratorium diperoleh kapasitas beban lateral dan simpangan sebesar 39.15 kN dan 45.88 mm dan hasil analisis SAP 2000 diperoleh kapasitas beban lateral dan simpangan sebesar 32.62 kN dan 33.73 mm. Rasio perbandingan Kapasitas pembebanan dan Simpangan Analisis SAP 2000 dan pengujian Laboratorium adalah sebesar 0,83 dan 0,74. Kata kunci: portal beton; bata ringan; beban lateral; simpangan. Abstract-Earthquake is a natural phenomenon due to tectonic and volcanic. Risks that arise include damage to buildings, injuries, death and other infrastructure damage. Earthquake loads in Structural Science are simulated into Lateral Forces and Cyclic Forces so that they are easy to model. The choice of lightweight brick as a wall can reduce the self-weight of the structure. System Application and Processing (SAP 2000) is used as a tool to analyze building structure modeling against working loads. This study aims to determine the comparison of the load-bearing capacity and deviation of the results of the Laboratory with the SAP 2000 application on the Lateral Force. Testing and Analysis of concrete portal with lightweight brick infill walls with dimensions of 1.00 m wide and 1.50 m high with the following properties 150/200 mm foundation, 150/150 mm column, 150/150 mm beam, 10 main reinforcement, 8 stirrup reinforcement and brick wall Lightweight AAC 60.20.10 cm. Testing of lightweight brick infill concrete portals in the laboratory and SAP 2000 Analysis using lateral forces as simulations of Earthquake Forces. The results of laboratory testing obtained lateral load capacity and displacement of 39.15 kN and 45.88 mm and the results of SAP 2000 analysis obtained lateral load capacity and displacement of 32.62 kN and 33.73 mm. The comparison ratio of loading capacity and deviation of SAP 2000 analysis and laboratory testing is 0.83 and 0.74, respectively.
