The design of a column is performed particularly to prevent any excessive deformation when it is used to support working load, and still have sufficient safety and reserve strength to withstand the load and stress without experiencing the collapse. The process of design or analysis generally begins with a compliant againt flexure, and the other requirements such as shear, crack, anchorage length were so that all requirment satisfied. The aim of this research is to get the stress of reinforced concrete column using the finite element method, so that it can get an evaluation of the design of reinforced concrete columns by comparing the stress design with the stress obtained from the finite element method. The calculations result shown that the enlargement deflection in horizontal direction is greater than the value of the enlargement deflection in vertical direction, that cause of the influence of axial forced and bending moment. From the results of stress analysis in steel and concrete by using the finite element method has a value less than fy and f'c used in the design. This shows the reinforced concrete column can withstand a greater load than the load value which was assumed the column on the balance condition

The increasing development of high-rise building construction with unique design in Indonesia today can not be denied. The high-rise buildings must have earthquake resistance because of Indonesia is a country that has the risk of an earthquake. This requires a multi-storey structure designer to be able to design a multi-storey building structure with various conditions and configurations. Based on that problems, a building will be designed with unusual shape by inclining the entire main structural column with a slope angle is 80o. And as a comparison, another building will be designed which uses vertical column. The building plan will be located in Banjarmasin, South Kalimantan, Indonesia.The building plans with inclined and vertical column use reinforced concrete material with Ordinary Moment Resisting Frame (OMRF) as a structural strength system. This system is determined by the location of the building based on Indonesian Earthquake Map 2012. The result of the analysis and design is the building with inclined column has greater internal force compared to a building with vertical column and requires a reinforcement of 70.89% more than the building with vertical column.Keywords: earthquake, inclined column, building, concrete reinforcement, vertical column

Perancangan balok dilakukan sedemikian rupa agar tidak menimbulkan retak berlebihan pada penampang sewaktu mendukung beban kerja dan tegangan lebih lanjut tanpa mengalami keruntuhan. Agar tidak terjadi keruntuhan tersebut, batang balok sebagai bagian dari sistem yang menahan lentur harus kuat untuk menahan tegangan tekan dan tarik pada balok tersebut. Oleh karena itu dalam teknik sipil klasik, penyelesaian analisis tegangan struktur di pakai metode-metode seperti kemiringan lendutan (slope deflection) dan distribusi momen namun di teknik sipil modern ini terdapat metode baru yaitu metode elemen hingga dengan prinsip dikritisasi yang membagi suatu benda menjadi benda-benda yang berukuran lebih kecil agar lebih mudah pengelolaanya.Tujuan dari penelitian ini adalah untuk mendapatkan tegangan yang diterima balok beton bertulang dengan menggunakan metode elemen hingga sehingga bisa mendapatkan suatu evaluasi perancangan balok beton bertulang dengan membandingkan tegangan yang di terima antara menggunakan metode konvensional dengan metode elemen hingga. Dari perhitungan yang telah dilakukan menunjukkan bahwa nilai pembesaran defleksi arah y (vertikal) lebih besar dibandingkan dengan nilai pembesaran defleksi arah x (horizontal), hal ini terjadi karena pengaruh dari beban vertikal yang diberikan dan juga konfigurasi balok yang digunakan dari struktur yang simetris. Tidak hanya itu dari hasil analisis tegangan pada tulangan dan pada beton di balok beton bertulang dengan menggunakan metode elemen hingga memiliki nilai yang lebih kecil bila dibandingkan dengan nilai fy dan f’c pada metode konvensional. Hal ini menunjukkan bahwa balok beton bertulang tersebut dapat menahan beban yang lebih besar dari pada nilai beban yang digunakan dalam perancangan balok bertulangan rangkap.Kata Kunci: Beton bertulang, Balok, Metode elemen hingga, Tegangan

Design of reinforced concrete T beams bridge with variation concrete strength is conducted to determine design of a bridge which can be built in remote area with a minimum concrete quality but still in accordance with the applicable safety standards. The bridge has a span of 15 m, a width of traffic lanes 2 x 5.5 m with variations concrete strength of K-200, K-225, K-250, K-275 and K-300. The calculations that have been done show that in cross section 2-2 , cross section 3-3 and cross section 4-4, the lower concrete strength will obtains more flexural girder reinforcement needs. However at cross section 1-1 the amount of reinforcement on every concrete strength has the same amount of reinforcement because the reinforcement ratio is the ratio of minimum reinforcement. Shear reinforcement of girder using the same diameter will produce the reinforcement needs with larger spacing while concrete strength increased. Maximum girder deflection that occurs will be smaller if the concrete strength increases. However, if the amount of reinforcement in the quality of K-200 more larger then the value deflection will be smaller compared with the quality of K-300. The lower quality of flexural strength concrete slab with the D16 will get smaller reinforcement spacing.Key word : bridge, T beams, quality variation, Upper structure
