Abstract

Runway adalah salah satu infrastruktur yang difungsikan sebagai area pergerakan pesawat saat lepas landas dan mendarat. Gradasi agregat dalam campuran beraspal memiliki peran krusial dalam menentukan sifat-sifat mekanik dan hidrolik campuran. Pada penelitian ini dilakukan pengujian Marshall dengan variasi durasi perendaman 60 menit, 90 menit, 120 menit, 150 menit, dan 180 menit dengan tujuan untuk mengetahui nilai karakteristik campuran dan daya tahan campuran menggunakan gradasi FAA dan gradasi. Berdasarkan hasil pengujian Marsahall diperoleh nilai stabilitas pada gradasi FAA dan BBA telah memenuhi standar spesifikasi dengan nilai stabilitas tertinggi berada didurasi perendaman 60 menit. Dimana nilai stabilitas pada gradasi FAA diperoleh nilai sebesar 1928,30 Kg dan gradasi BBA diperoleh nilai sebesar 1598,01 Kg, sedangkan nilai stabilitas terendah berada didurasi perendaman 180 menit. Kemudian dari nilai stabilitas didapatkan nilai durabilitas campuran pada gradasi FAA dan BBA sudah memenuhi standar, dimana pada perendaman 90 menit diperoleh niali IKS tertinggi yaitu sebesar 98,97%.

Abstract

Structural stability in construction, especially in buildings exposed to lateral forces due to earthquakes, is very important to consider. This research aims to explore the effectiveness of using Independent Wire Fibre Core (IWFC) steel wire rope braces in strengthening two-dimensional (2D) concrete portals. The method used is a series of laboratory tests to measure the performance of concrete portals equipped with IWFC braces. Concrete portals with dimensions of 1.00 m in the width direction and 1.50 m in the height direction were tested with lateral loading to simulate the effects of earthquakes. The test results showed that the use of IWFC braces increased the load resistance capacity of the portal by 16.13%, from 14.00 kN to 26.13 kN, and reduced the deviation by 30.43%, from 2.30 mm to 1.68 mm. In addition, the analysis showed an increase in the response modification factor (R) from 4.69 to 5.03, while the Cd value of the non-braced portal was 3.29 using braces was 3.02 and the Ω0 value of the non-braced portal was 3.50 and after using braces was 2.84. These findings open up opportunities for the application of better structural strengthening techniques in order to improve the safety and stability of buildings in earthquake-prone areas.
