Abstract

Stress-strain relationship is the main parameter to identify the strength, ductility and behavior of the structure. Various constitutive models were created in order to simplify the analytical approach of concrete behavior. In this paper, the behavior of reinforced concrete column is modeled using Attard and Setunge’s (1996) and Mander’s (1988) stress-strain constitutive model. The appropriate model for reinforced concrete column was determined based on the existing experimental data. Two-dimensional simulation of reinforced concrete column using fiber-based cross-sectional analysis in MATLAB is sighted. And the performance of the reinforced concrete column from the experimental data is compared with the analysis result from the simulation. There are two comparation methods used in this research. The first method is to compare the linear regression with the reference line. The smallest degree between the linear regression and the referrence line is expected. The second method is to compare the Root Mean Square Defiation (RMSD) value. The smallest RMSD value is expected to get the most suitable constitutive model compared to the experimental data. From the computational process, it was found that Mander’s Constitutive model is preferaed to be used in further analysis problem concerning reinforced concrete column

Abstract

Kemacetan bersifat nonrecurrent disebabkan oleh peristiwa yang tidak dapat diprediksi seperti terjadi akibat kendaraan berat mengalami risiko kerusakan. Biasanya kendaraan akan berhenti disalah satu lajur sehingga mengurangi kapasitas jalan dan jalan tidak mampu menampung volume lalu lintas yang tinggi. Selain itu, membutuhkan waktu yang lama untuk proses evakuasinya sehingga akan memperpanjang antrian kemacetan. Hal ini akan menimbulkan kerugian bagi pengguna jalan. Sehingga perlu dibuatkan model hubungan antara variabel volume lalu lintas, biaya kerugian dan lama waktu penanganan. Digunakan metode regresi sederhana untuk membuat model tersebut. Persamaan model yang didapatkan yaitu ketika waktu penanganan 0,5 jam y =-95848463,493+66456,613X; 1 jam y =-191696926,994+132913,227X; 1,5 jam y =-287545390,476+199369,840X; 2 jam y =-383393853,990+265826,454X dan 3 jam y =-575090781,012+398739,681X dengan variabel y biaya kemacetan (Rp) dan x volume lalu lintas (skr). Persamaan model tersebut digunakan ketika kapasitas jalan 4/2D yang awalnya 3319,68 skr/jam menjadi 1659,84 skr/jam dengan batas volume lalu lintas minimum 1660 skr/jam.

Abstract

The East Surabaya area is one of the industrial and office centers. The high activity of the people in the city of Surabaya will affect transportation mobility which is marked by the growth of road traffic volume which continues to increase rapidly. This area has a lot of community mobility to and from the East Surabaya area. This caused congestion on several roads. Congestion is the main problem of transportation in urban areas. At certain hours there is often a spike in traffic volume that exceeds the capacity of existing roads. This is related to the starting hours of activities in East Surabaya and the ending hours of activities from East Surabaya which coincide, causing traffic jams. The East Surabaya area is divided into two times when the traffic volume increases, namely morning and evening. Based on this, this study aims to determine when there is a spike in traffic volume. The method used is a traffic volume survey, looking for peak hour volume based on cur/hour units and determining when peak hours occur. The results showed that the highest volume in direction 1 during peak hour occurred on Friday in Jalan Panjang Jiwo with a volume of 5947 cur/hour and direction 2 occurred on Friday on Jalan Jemursari. The average time for an increase in traffic volume in the East Surabaya area in the morning is 07.00 to 08.35 and in the afternoon is 15.35-18.00.

Abstract

In Mataram City, the capital of West Nusa Tenggara Province, many road sections have deteriorated, reducing road comfort, safety, and mobility efficiency. Typical forms of road damage, such as cracks, potholes, deformation, and surface wear, demand regular maintenance and repairs to extend road service life. This situation underscores the need for a thorough mapping of road pavement damage to provide a comprehensive overview of the road network’s condition and to support effective maintenance planning. The mapping of pavement damage in Mataram City is also expected to inform more effective decision-making in road management. This study aims to review previous research on pavement damage mapping and apply the findings to road sections in Mataram City. This empirical, data-driven approach is anticipated to provide a thorough perspective on pavement conditions and serve as a foundation for the local government’s efforts to create more effective and efficient road maintenance policies. This study employs a systematic literature review approach to analyze and synthesize existing research regarding pavement damage in road sections using the PCI and Binamarga Methods on Mataram City roads. This study is classified as qualitative research, focused on extracting and synthesizing information from academic papers. Based on the research results from several journal reviews, in the city of Mataram,, several roads still experience visual damage to the pavement surface, including cracking, depression, patching and utility cut patching, and potholes. In addition, the results show that several roads experience fair-level damage based on the PCI method, and some have less than 50% damage to the road surface based on the Binamarga method
