Abstract

Today, Practitioners of Civil Engineering in Indonesia are still using SNI 2847:2013 as code for reinforcement concrete design. As we know that SNI 2847:2019 been published, but practitioners still not yet use it.The point of design and evaluation in SNI 2847 code is reduction factor (ɸ) that could influence strength design of structure base on it behaviour. Load in Column is not just axial load, but flexural and combine of axial and flexural. This behavior makes the column has variate reduction factor and it can shown by interaction diagram. This research is compare between SNI 2847:2013 and SNI 2847:2019 for column with section 400x500, fc’ 20 MPa and reinforcement ratio 1%. Result of this research is compare between SNI 2847:2013 and SNI 2847:2019 for column with variation fy is not too significant. So when the column of SNI 2847:2013 inspected or evaluated by SNI 2847:2019 is not distinction.

Abstract

This study aims to determine the difference in structural beam design using SNI 2847-2002, SNI 2847-2013 and SNI 2847-2019 by comparing the bending and shear reinforcement in the case study of the Faculty of Health Sciences Building, University of Borneo Tarakan. The results of the comparisons include: the maximum reinforcement ratio at SNI 2847-2013 and 2019 is around 16,667% smaller than SNI 2847-2002, the flexural capacity of the beam design results from SNI 2847-2013 and 2019 increases by about 12.5% compared to SNI 2847-2002, The shear capacity of concrete (Vc) designed with SNI 2847-2013 and 2019 increased by about 2% compared to SNI 2847-2002, as well as the design shear capacity of the accumulated concrete and shear reinforcement designed by SNI 2847-2013 and 2019 increased no more than 1% compared to SNI 2847-2002.

Abstract

This study aims to determine the performance on a single weave that occurred on Jl.Niaga I - Jl. Yos Sudarso, Tarakan City. The performance is capacity, degree of saturation, speed, and travel time. With these performance parameters serve as based of planning in transportation infrastructure. The results of this study are also expected to provide recommendations to users, planners and policy makers in an effort to solve traffic problems, especially to reduce the delay that occurs in a single wave that occurred on Jl Niaga I-Jl. Yos Sudarso Kota Tarakan.

Abstract

Use of wood construction in Indonesia is decrease significant than concrete and steel. While it is, government by National Standardization Corporation (BSN) had been published Indonesian National Standard about Wood Construction Design Spesification with code SNI 7973:2013. This code absolutly influential the old code which is PKKNI 1961. SNI 7973:2013 is regulate about Load esistance Factor Design (LRFD) and Allowable Stress Design (ASD), while PKKNI 1961 just use ASD method. In case SNI 7973:2013 have been use ASD, but it is different to PKKNI 1961. This research is would to find the different betwen SNI 7973:2013 and PKKNI 1961 to tension member with dimention 5/10, 6/12, 8/12 and 10/10. Result of research to tension member show that LRFD 100%, ASD 65,1% and PKKNI 111,4%.

Abstract

Untuk mendesain tulangan pelat pada struktur flat plate ber-hollow dua arah perlu penyederhanaan dari bentuk distribusi tegangan yang terjadi, caranya adalah dengan memanfaatkan lebar efektif dari column strip area dan middle strip area, dengan cara ini bentuk momen yang berkontur 3-dimensi diubah menjadi lembaran-lembaran 2-dimensi yang sederhana. Metode desain tulangan memanfaatkan lebar efektif pelat dari struktur flat plate ber-hollow dua arah yang menggunakan hollow berbentuk trapesium, selanjutnya tegangan pelat yang sebelumnya tidak  merata didistribusikan merata pada lebar efektif pelatnya dengan konsep redistribusi momen. Hasil desain lentur dengan menggunakan tulangan ber-diameter 13 mm maka diperoleh spasi terkecil dan terbesar pada column strip sebesar 75 mm dan 140 mm, sedangkan spasi terkecil dan terbesar pada middle strip adalah sama besar yakni 140 mm. Hal ini membuktikan bahwa tegangan pada bagian column strip terbilang lebih bervariasi, sedangkan pada bagian middle strip terbilang relatif kecil dan sama besar. Kata kunci - Lebar Efektif Pelat, Redistribusi Momen
