Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh tinggi balok H = 1/12 L-1/10 L terhadap luas tulangan balok yang digunakan pada konstruksi bangunan. Variabel yang ditinjau dalam penelitian ini merupakan tinggi balok dan luas tulangan pokok. Model struktur portal yang ditinjau ialah portal dalam bentuk tiga dimensi dan bertingkat tiga. Analisis struktur dilakukan dengan menggunakan bantuan Aplikasi SAP 2000 versi 20.2. Perhitungan beban mati dan beban hidup gedung ini berdasarkan pada peraturan SNI 03-1727-2013, perhitungan beban angin berdasarkan pada Pedoman Peraturan Pembebanan Indonesia untuk Gedung 1987, perhitungan beban gempa berdasarkan pada SNI 1726-2012. Hasil dari penelitian ini menunjukkan bahwa terjadi pembesaran luas tulangan balok dari tiap-tiap penampang yang berbeda, dimana semakin besar penampang/tinggi balok semakin besar luas tulangan, pengaruh besarnya luas tulangan terjadi pada balok H=1/10L-1/11L, Perbedaan luas tulangan berdasarkan perencanaan berdasarkan momen ultimit (Mu) terhadap balok adalah (30x40)cm= As = 397,38 mm2, As’ = 198,69 mm2. (20x35)cm= As = 299,03 mm2, As’ = 114,51 mm2. (25x40)cm= As 331,15 mm2, As’ 165,58 mm2. (20x30)cm= As 193,13 mm2, As’ 96,56 mm2. (25x35)cm= As 286,28 mm2, As’ = 143,14 mm2. (20x25)cm= As = 157,23 mm2, As’ 78,62 mm2. Luas tulangan balok yang lebih efisiensi dalam perencanaan gedung ini adalah balok 1/12 L ukuran (25x35)cm dan ukuran (20x25)cm.

Abstract

This study aims to determine the extent of the influence of column orientation or direction on the area of reinforcement to be used in building construction. The variables examined in this study were column orientation and reinforcement width. In the first analysis, the column orientation was tried with the X direction plan, so that the column dimensions b = 30 cm and h = 40 cm were obtained. The second analysis tried the column orientation with the Y direction plan, with the same column dimensions in order to obtain b = 40 cm and h = 30 cm. Structural analysis was performed with the help of SAP2000 version 20.2. The results showed that at the same construction with column orientation in X and Y direction, the axial load (Pu) and ultimate moment (Mu) were not much different. These results affect the area of reinforcement obtained from calculations based on the Mu value. The X direction column orientation obtained the value of Pu = -67240.86 Kg and Mu = 4001.97 Kgm with a reinforcing area of 2959.454 mm2. Whereas for the Y direction column orientation the value of Pu = -64776.95 Kg and Mu = 3306.4 Kgm with a reinforcing area of 3055.595 mm2. The percentage value (%) to X is Pu = -3,664%, Mu = -17,381%, and for As = 3,249%.

Abstract

Truss structure which is often used for primary girder  of bridge of highway is a Warren or Pratt  type, what is its use combined with two horizontal truss attached below and above functioning as truss of wind bracing. Though have space dimension, but its structure is not pure of truss space, practically its analysis is done to each truss, vertical and horizontal which is considered as plane truss.  Truss structure with a trianggular  cross section type represent other alternative from structure truss which can is also used as a highway bridge structure, and this type truss represent purification truss space. Beside that, structurally entire element truss together have the contribution to arrest forced from all direction, and cause this type truss is more stable in arrest torsion and shear compared to a other structure truss bridge type. Method used to analyse structure of truss that is stiffness matrix method by means of  assist calculation of Microsoft Excel 2007. Result to be reached from this analysis is to find relation of between span length, depth of truss and to the number of panel, to weight of structure and translation of a joint; utilize to get optimum weight and translation of joint. Pursuant to result analyse to three group of sample truss model, each group consisted of three sample, in each depth condition of certain truss, there's only one optimum weight value at one particular truss, and angle of inclination of diagonal and also the span-depth ratio and depth of  economic truss still stay in gyration of economic values is such as those which applied for plane truss
