Abstract

The design of the steel frame structure for beam, column and beam-column elements which takes quite a lot of time makes engineers it difficult forin the field of building construction. Engineers have to do several experiments to findsteel profiles IWF and HCS that are safe, efficient and economical. The problems that arise due to the length of the design process are the basis for this research. The research was conducted on 100 profiles IWF and HCS which consisted of 81 profiles IWF and 19 profiles HCS. The analysis was carried out with reference to SNI 1729:2015. The results of this study are in the form of moment capacity graphs and tables of axial capacity of steel profiles as well as coefficients of m and U. Moment capacity graphs and tables of axial capacity of IWF and HCS profiles produced can assist in designing safe and efficient steel profiles as beam, column and column elements. column beam. Efficiency testing of steel profiles used as beam-column elements proves that the safety profile of the axial resisting profile and ultimate moment is close to the value 1.

Abstract

Indonesia is an earthquake-prone country related to its geological position located in the Pacific ring of fire. Therefore, it is necessary to mitigate earthquake disasters so as not to cause much loss, both property and life. One of them is by introducing the walls of earthquake resistant composite house (RKTG) made from sandwich composites. The purpose of this study was to investigate the effect of matrix and skin thickness on the mechanical strength of sandwich composites with polyurethane cores.). Sandwich composites use variations of glassfiber reinforced polymer (GRP) and glassfiber reinforced concrete (GRC) skins and variations in skin thickness of 6 mm and 10 mm. The adhesive used is polyester resin with methyl ethyl ketone peroxide catalyst. The manufacturing process of making sandwich composites uses the hand lay-up technique with a sandwich composite thickness of 10 cm. The results showed that GRP skins have better mechanical properties than GRC skins. Skin thickness can also improve the mechanical properties of sandwich composites. The best mechanical strength was obtained in the GRP skin type with a skin thickness of 10 mm, namely a flexure strength of 1.63 MPa, a compressive strength of 10.7 MPa, and a tensile strength of 0.08 MPa.

Abstract

Abstrak: Analisis Debit Puncak Dengan Pendekatan Metode Hidrograf Satuan Sintetis ITB2 Dan Hec Ras 5.0.7 Pada Das Air Manna Bagian Hilir. Tujuan dari penelitian ini adalah menganalisis debit puncak Das Air Manna Bagian Hilir dan menganalisis titik lokasi yang akan melimpas berpotensi banjir menggunakan software HEC-RAS versi 5.0.7. Penelitian ini menggunakan data sekunder berupa curah hujan harian selama 10 tahun dari 3 stasiun hujan. Metode yang digunakan untuk menentukan debit puncak adalah menggunakan pendekatan metode Hidrograf Satuan Sintetis (HSS) ITB 2 yang kemudian diintegrasikan kedalam program HEC-RAS versi 5.0.7. Hasil penelitian ini menunjukkan debit puncak pada daerah aliran sungai Air Manna sangat tinggi dibandingkan dengan fakta yang ada dilapangan sehingga perlu dilakukan penelitian ulang dengan titik tinjauan yang lebih banyak. Berdasarkan hasil analisis dari program HEC-RAS didapat bahwa Sungai Air Manna Bagian Hilir sudah tidak mampu menampung debit banjir, daerah potensi banjir terjadi disepanjang STA 5770 (Desa Batu Kuning) sampai ke STA 0 (Desa Ketaping).

The research aims to analyze the peak discharge (Maximum) of Air Manna’s DAS Downstream and the location points that it will potentially overflow. This research used HEC-RAS program with version 5.0.7. The research’s Secondary data is in the form of daily rainfall for 10 years from 3 rain stations. The method used to determine the peak discharge was using the ITB 2 Synthetic Unit Hydrograph (HSS) method which was then integrated into the HEC-RAS progam with version 5.0.7. The results showed top of flow on stream Manna river is very high than by the fact in the field, so need to do repetitive research in more spot of river. Based on the results of the analysis of the HEC-RAS program, it was found that the Air Manna River Downstream was unable to accommodate the flood discharge, the potential flood areas occurred along STA 5770 (Batu Kuning Village) to STA 0 (Ketaping Village).
