Abstract

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

Abstract

Pemadatan tanah merupakan salah satu pekerjaan penting dalam setiap proyek perkerasan jalan. Pemadatan tanah berfungsi untuk meningkatkan kekuatan tanah yang memberikan daya dukung kepada lapisan jalan di atasnya, serta juga berfungsi untuk mengurangin besar penurunan tanah yang tidak diinginkan. Dalam setiap pemadatan tanah diperlukan kadar air optimum untuk mencapai kepadatan maksimum yang dapat diketahui dengan uji proctor . Uji proctor yang masih manual dalam pemberian bebannya mengakibatkan membutuhkan tenaga manusia yang cukup besar dalam penggunaannya. Pada penelitian ini membandingkan uji proctor modified dengan pemodelan alat tekan pemadat modifikasi dengan menggunakan tekanan kontak alat berat pemadat tanah dalam usaha mengantikan uji proctor manual dengan alat modifikasi yang lebih praktis. Tanah yang digunakan adalah tanah timbunan pilihan, berasal dari Desa Gedung Agung, Kecamatan Jati Agung, Lampung Selatan. Pengujian alat tekan pemadat modifikasi ini terdiri dari 4 tekanan berbeda yaitu 1,667 Mpa; 6,2 Mpa; 7 MPa dan 8,4 MPa, menggunakan tiga sampel tanah pada masing-masing tekanan. Hasil pengujian di laboratorium menunjukkan bahwa berat volume maksimum (γdmaks) sebesar 1,706 gr/cm3 pada pengujian metode proctor modified dengan hasil pada alat tekan pemadat modifikasi didapat nilai tekanan sebesar 8 MPa.
