Abstract

Vertical stiffeners are usually used to resist shear force or to stiffen web plate in accordance with local buckling. Vertical stiffeners which have torsional stiffness can disturb warping of the beam. So the vertical stiffeners can increase the torsional stiffness of the beam. The relation between the torsion of vertical stiffener to warping of the beam must firstly be found. By the boundary conditions of the beam at the two ends and at the vertical stiffeners, all integration constants of diferential equation of each field rotation can be found. Analysis can be done on various thickness and various numbers of vertical stiffeners. It can be concluded that the increase of torsional stiffness caused by the increase of the of vertical stiffener thickness  are significant. The gradient of the torsional stiffness increase tend relatively smaller at the greater number of vertical stiffeners.Keywords: vertical stiffener, warping, torsionPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3942[How to cite: Tudjono, S., 2006, Torsi Balok Baja Berprofil I Berpengaku Vertikal, Jurnal Media Komunikasi Teknik Sipil, Volume 14, Nomor 2, pp. 150-155]

Abstract

The Design of Leho Bridge in Karimun Coastal Area, Riau Islands, based on the needs of a transportation infrastructure that connecting the Old Town Area with Sei Bati Airport. This Bridge Structure is designed by using an Arch Bridge Structure considering that it’sfunction also as a monumental building.Based on the results of highway capacity analysis, the bridge’s width designed as 9,00 m with 2/2 UD type which the pavement is 7,00 m width and each of the pedestrians are 1,00 m width. Then the bridge’s  span is determined as 60,00 m, based on the gulf’s geometry and the boat’s traffic under the bridge. The Clearance below the bridge is affected by the highest water level and the boat’s heightwhich on this case is taken as 11,00 m.Through the design and the calculation with Load and Resistance Factor Design’s method we found the section of the arch rib is a box formed steel profile which size is 900.900.40.40 with the yield stress is 290 MPa. While the main beam using a box formed steel profile which size is 900.400.30.30 with the yield stress is 290 MPa. The foundation system is designed by using a group of sheet piles which the diameter is 60 cm as much as 24 piles on each abutments.

Abstract

ABSTRAK Pada pekerjaan perbaikan atau perkuatan struktur dengan melakukan pengecoran beton baru yang melekat pada bidang beton lama akan membentuk semacam lapisan interface beton. Penelitian mengenai bagian interface dilakukan oleh Momayez et al., 2004 dan Hak-Chul Shin et al., 2010. Namun penelitian tersebut belum memasukkan parameter peran tulangan pada interface dalam pengujiannya. Sedangkan penelitian ini mengkaji peran tulangan terhadap kekuatan geser pada interface dan pola retak yang terjadi. Benda uji yang digunakan berbentuk kubus berdimensi 20 cm x 20 cm x 20 cm sebanyak 30 buah yang tersusun dari dua bagian, yaitu beton lama sebesar 2/3 bagian dan beton baru sebesar 1/3 bagian dari kubus benda uji. Variasi beda umur pengecoran terdiri dari 7, 14, dan 28 hari. Variasi bentuk dan diameter tulangan terdiri dari bentuk Tulangan I dan Tulangan U dengan diameter 8 mm dan 10 mm. Dari penelitian disimpulkan bahwa benda uji Tanpa Tulangan mempunyai kapasitas geser paling kecil, sedangkan benda uji dengan Tulangan U memiliki kapasitas geser yang lebih besar dibandingkan dengan Tulangan I. Hal ini dikarenakan penambahan tulangan memberikan pengaruh kekuatan geser yang lebih besar serta Tulangan U bersifat lebih kaku, interlocking dan lekatan antara beton dan tulangan lebih kuat dibandingkan dengan Tulangan I. Kata kunci: interface, kapasitas geser, peran tulangan, pola retak ABSTRACT Alpha In the work of repair or strengthening the structures by casting new concrete inherent in the old concrete surface will form concrete interface. Study on the interface has already been done by Momayez et al., 2004, and Hak-Chul Shin et al., 2010. However, these studies did not include the interface parameters of the influence of steel reinforcement in the test yet. While this study examines the influence of steel reinforcement to the shear strength at the interface and the crack patterns that occur. Specimens used cuboid dimensions 20 cm x 20 cm x 20 cm 30 pieces are composed of two parts, the old concrete for 2/3 parts and new concrete for 1/3 part of the cube specimen. Variations apart in age casting consisting of 7, 14, and 28 days. Variations in the shape and diameter of the steel reinforcement consists of I Reinforcement and U Reinforcement with diameters of 8 mm and 10 mm. From the study concluded that the specimen without steel reinforcement has the smallest shear capacity, whereas specimens with U Reinforcement has a shear capacity greater than I Reinforcement. This is due to the addition of steel reinforcement influence greater shear strength and U Reinforcement is more stiff, interlocking and bonding between concrete and reinforcement stronger than I Reinforcement. Keyword: interface, shear capacity, influence of steel reinforcement, crack pattern

Abstract

Designing architecture development for Heritage Building should handled in carefully attention due to regulation has been protected the artefact. Most of development actions such as rehabilitation, renovation,redesign or development the individual building or building complex are related to develop the building into new function or other development in the context of extention of the needs. Conservation Catagorysation Study is one of the procedure can be used in which is provided through observation stage,documentation, catagorysation analysis to the heritage building complex as approach strategy before provide designing architecture developmentThis research just an example of guidline technique in the process of architectural design in developing heritage building complex based on preservationconservation strategies.Specific approach of architectural context will provide in the future continuing research from other discipline of approach such as archeologies approach to bring final conservation catagorysation comprehensively.
