Abstract

Permasalahan kerusakan jalan yang terjadi, menunjukkan kinerja jalan yang ada saat ini tidak seperti yang diharapkan. Jalan dengan struktur perkerasan kaku mengalami kerusakan akibat beban lalu lintas yang melebihi kapasitas. Struktur perkerasan menjadi lemah atau berkurang kemampuannya untuk menerima beban sehingga perlu dilakukan penguatan struktur perkerasan kaku. Tujuan penelitian untuk mengetahui desain over slabbing yang meliputi kuat tekan, kuat lentur, modulus elastisits, permeabilitas dan susut beton sebagai material penguat perkerasan kaku dengan bahan tambah fly ash. Metode yang digunakan dalam penelitian ini adalah metode eksperimen. Penelitian dirancang dengan empat perlakuan, tiap perlakuan diulang tiga kali. Hasil penelitian menunjukkan bahwa material over slabbing untuk penguat perkerasan kaku menghasilkan nilai kuat tekan beton rata-rata tertinggi pada variasi kadar fly ash 10% sebesar 24,05 Mpa. Kuat lentur rata-rata tertinggi pada variasi kadar fly ash 10% sebesar 3,02 Mpa, ini tidak memenuhi syarat kekuatan rencana pada umur 28 hari sebesar 3,78 MPa. Modulus elastisitas beton rata-rata tertinggi pada variasi kadar fly ash 10% sebesar 23,066 103 Mpa. Nilai koefesien permeabilitas beton terbesar pada variasi kadar fly ash 30% sebesar 1,723 10-5 m/det dan nilai koefesien permeabilitas beton terkecil pada variasi kadar fly ash 10% sebesar 3,393 10-5 m/det, nilai koefesien permeabilitas beton seluruhnya memenuhi syarat ACI 301-729 sebesar 1,5 10-11 m/det. Susut terbesar terjadi pada baton dengan variasi kadar fly ash 30% sebesar 702,222 microstrain sedangkan susut terkecil terjadi pada beton dengan variasi kadar fly ash 10% sebesar 502,500 microstrain

Abstract

Building is a physical form of work that functions as a place to live, for religious, social, cultural activities, as well as special activities. In building construction the types of structures that can be used steel construction and reinforced concrete structures. The two structures differ in terms of nature, material, method of implementation and most importantly in terms of strength and cost. The purpose of this research is to plan reinforced concrete structures using the Etabs program to determine the dimensions of columns and beams, as well as to analyze the cost of reinforced concrete columns and beams. As a comparison to the structure and cost of elements columns and beams steel construction, is this alternative more efficient and economical or vice versa. Research using comparative method. The comparative method is research that is intended to determine the level of difference a variable from two different groups.The results of the research show that a comparison of structures based on the strength to carry the same load on column and beam elements is obtained for existing steel construction K1-H400, K2-H300, B1-WF500, B2-WF450, B3-WF350, B4-WF300, B5-WF200, B6-WF250, B7-WF150, B8-WF400. while for reinforced concrete the planning results using the Etabs program obtained K1 50x50cm, K2 40x40cm, B1 30x60cm, B2 25x50cm, BA 20x40cm. Cost comparison between steel construction and reinforced concrete for column and beam elements with the existing price of steel construction Rp. 2,491,416,316. while the price of reinforced concrete structures is Rp. 789,569,564. the cost of reinforced concrete structures is cheaper than steel construction with a difference in costs of Rp. 1,701,846,752 or a percentage of 68.3 %
