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 use of electrical energy for each region is increasing every year, along with the community’s increasing needs. Surabaya, a metropolis in Indonesia, is listed as the third-largest user of electrical energy in Indonesia. The community has widely used solar panels as new renewable energy, such as in the construction of traffic lights, street lighting, and several households. This study aims to determine the daily performance profile of the daily value of voltage, current, and energy stored from solar panels with different types of solar panels, namely, using polycrystalline and monocrystalline solar panels mounted on the roof of the house. Data retrieval was carried out with an interval of data collection every hour when the sun is high enough until the afternoon (06:00 WIB – 18:00 WIB). The results showed that the average voltage value for monocrystalline solar panels was 21.09 V and polycrystalline solar panels were 19.32 V. In addition, the output current values for monocrystalline and polycrystalline solar panels were 0.903 A and 0.27 A. Meanwhile, the monocrystalline output power value was 19.72 W and polycrystalline 5.43 W. Based on the research data, it can be concluded that the energy stored in the battery and the efficiency value for each monocrystalline solar panel produces a higher output value than that produced by polycrystalline solar panels, 12,98%, and 4.04%. However, polycrystalline solar panels that produce a lower and stable electric current can extend the lifetime of the battery where the electric charge is stored from the solar panel.

Abstract

This preliminary study aims to determine the daily profile of the power output generated from solar panels, with variations in the house’s roof angles of 15º, 0º, 15º. Tilt angle investigation expects to discover the impact of placing solar panels on the slope of the tile used on the house’s roof. The collecting data of this study was investigated the data of current and voltage every hour that produced by solar panel. Besides, this study also comparing the result of total energy output value for daily profile of solar panel during ten hour per day (start from 7 am to 5 pm). The results show that solar panels with an angle of -15º at 07:00 – 10:00 WIB have higher output voltage and current than other angle variations. At a tilt angle of 0º, the output voltage and current of the solar panel are higher at 11:00-14:00 WIB, while at a tilt angle of 15º in the afternoon. Based on observations, each solar panel with exposure for 10 hours obtained the total energy value for polycrystalline solar panels with a tilt angle of -15º of 258.44 Wh, solar panels with an angle of 0º obtained an energy value of 263.64 Wh, and a tilt angle of 15º obtained energy values 260.69 Wh. The photonic energy emitted for 10 hours is 2097.47 Wh. The energy efficiency value for each polycrystalline solar panel is 12.32% for the angle of -15º, the angle of 0º is 12.57%, and 12.43% for the angle of 15º. In conclusion, variations in the angle of the solar panels have significant effect on the voltage, current, and energy generated from polycrystalline solar panels in every hour. However, based on the data result the total energy exposure and the efficiency value for each variation angle has no significant different. Pyramid-shaped house roof construction has the advantage of increasing the value of the cross-sectional area of the tile, which has the opportunity to install wider-sized solar panels so that a greater value of electrical energy is obtained.
