Abstract

Penelitian ini membandingkan struktur bangunan 3 lantai beton bertulang tahan gempa dengan metode Sistem Rangka Pemikul Momen Menengah (SRPMM) dan Sistem Rangka Pemikul Momen Khusus (SRPMK) pada wilayah gempa IV. Analisa dan evaluasi kinerja dilakukan menggunakan analisa pushover yang built-in pada SAP2000. Dimensi struktur yang digunakan pada SRPMM dan SRPMK direncanakan sama. Perhitungan struktur antara kedua metode tersebut menghasilkan perbedaan pada luasan tulangan, dan persamaan pada nilai daktilitas struktur (μΔ) serta faktor reduksi (R). Luasan tulangan SRPMM lebih besar dibanding SRPMK, sedangkan nilai daktilitas struktur (μΔ) dan faktor reduksi (R) pada kedua metode adalah sama yaitu (μΔ) = 3,36 dan R = 5,37. Persyaratan SNI 03 – 1726 – 2002 untuk SRPMM adalah μΔ = 3,50 dan R=5,50; sedangkan untuk SRPMK (μΔ = 5,20 dan R=8,5). Jika dibandingkan antara hasil yang diperoleh dengan syarat SNI 03–1726–2002, menunjukkan bahwa nilai daktilitas dan faktor reduksi pada SRPMM memenuhi persyaratan, sedangkan pada SRPMK tidak memenuhi. Besar target perpindahan maksimum pada struktur SRPMM menurut rumus dari SNI 03–1726–2002 dan FEMA (273/356) berturut-turut diperoleh sebesar 0,122 m dan 0,77 m. Sedangkan struktur SRPMK berturut-turut sebesar 0,75 m dan 0,77 m. Evaluasi kinerja struktur menggunakan analisa pushover masing – masing masih berkinerja IO (Intermediate Occupancy).

Abstract

Kegagalan struktur rangka momen baja di Amerika pada tahun 1994 akibat gempa Northridge memberikan pengetahuan bahwa material baja yang memiliki sifat daktilitas tinggi dapat menjadi getas jika tidak didetailkan dengan baik. Kegagalan-kegagalan yang terjadi membuat AISC membentuk satuan tugas the AISC Connection Prequalification Review Panel (CPRP) untuk melakukan evaluasi dan penelitian terkait sambungan. Salah satu sambungan yang dievaluasi adalah sambungan Bolted Flange Plate (BFP). Penelitian ini membahas tentang analisis numerik model sambungan BFP dengan menggunakan program bantu ANSYS kemudian hasil analisis dibandingkan hasil pengujian eksperimental yang dilakukan oleh Yilmaz, et al. (2019). Hasil analisis numerik dan hasil eksperimental menunjukan panel zone mengalami pelelehan di akhir pembebanan. Kapasitas momen dan rotasi yang dihasilkan oleh model numerik adalah 247,36 kN-m dan 4,83% dengan selisih antara model numerik dan eksperimental sebesar 4,05%.

Abstract

Salah satu kegiatan peningkatan jalan adalah pelapisan ulang permukaan jalan ( overlay ). Sebagai bahan overlay dapat digunakan aspal beton ( AC ) atau Hot Rolled Sheet ( HRS ). Direktorat Jenderal Bina Marga dengan keterbatasan anggaran selalu mencari yang terbaik dari sisi teknis dan ekonomi diantara AC dan HRS. Permasalahannya, penggunaan AC dan HRS sebagai bahan overlay bagaimana sisi teknis dan ekonomis ? Metode pemeriksaan bahan dan mixed design yang digunakan dalam penelitian ini mengikuti standart Bina Marga. Hasil pemeriksaan menunjukkan bahan pembentuk AC dan HRS telah memenuhi syarat, kemudian setelah dilakukan mix design, proporsi aspal untuk HRS = 7,8 % lebih besar dari aspal untuk AC = 6,1 %. Proporsi agregat kasar HRS lebih kecil dari AC, tetapi proporsi agregat halusnya lebih lebih besar. Tinjauan dari segi teknis, HRS lebih tahan terhadap kelelehan, pengaruh cuaca, lebih fleksibel dan lebih mudah dikerjakan daripada AC, tetapi dari segi ketahanan terhadap deformasi permanen kurang baik dibanding AC, karena stabilitas HRS lebih rendah. Tinjauan dari segi ekonomis, ternyata biaya  HRS lebih murah 14,01 % dibandingkan dengan biaya AC. Hal ini karena penggunaan HRS lebih tipis dari AC, walaupun harga HRS per m3 lebih mahal dari harga AC per m3.

Abstract

The development of geopolymer concrete is one of the most significant breakthroughs to replace the OPC concrete causing global warming issues. Investigations on the structural behavior of geopolymer concrete are limited and still need adjustments in numerical simulations to experimental results in previous studies. This study investigated the flexural behavior of geopolymer concrete as a structural member using the numerical method. The utilization of the finite element method is an alternative to widely determining the structural behavior of geopolymer concrete as a construction material. In this study, the author refers to the research conducted by Pham et al. The research developed a four-point bending test with variations in tensile steel reinforcement ratio. The results of the experimental tests that Pham has carried out will be verified by numerical simulation in three dimensions. The validation of experimental specimens with numerical specimens is done to compare the moment-curvature and the crack pattern of concrete. Numerical investigation accurately captures the structural behavior of moment-curvature and crack pattern of geopolymer concrete. The moment maximum deviation between experimental and numerical results is 1.3 to 2.4%. However, there are differences in the number and length of cracks in the bending moment area. The difference of crack pattern in the bending moment area between experimental results and numerical results due to the modeling did not consider the input of fracture energy. The experiment from referenced studies did not include fracture energy data, so the 3DNLFEA modeling used the fracture energy value of OPC concrete.

Abstract

Geopolymer concrete that has polymer formwork is very likely to be used as reinforced concrete material with several advantages. The advantages of geopolymer concrete when compared to portland cement concrete are: resistant to acidic environments (corrosion resistance), better bond strength of reinforcement with concrete material, stable at high temperatures, higher fracture energy. Previous experimental studies found that the tensile strength, bond strength, and fracture energy of geopolymer concrete were better, leading to the hypothesis that the ductility value of geopolymer concrete was better than portland cement concrete. The identification of ductility values based on the compressive strength of concrete will be carried out in research using the finite element method using the 3D ATENA program. Several specimens with compressive strength of 25 MPa, 30 MPa, 35 MPa, 40 MPa, and 45 MPa were compared with their ductility values. The results showed that the 25 MPa specimen had the highest ductility value with 5.33, while the lowest ductility value is 45 MPa specimen with 3.39.

Abstract

The inclusion of fly ash class C, which is widely available locally, can influence the progress of strength and durability qualities of geopolymer concrete when exposed to significant environmental conditions. Alternative geopolymer combinations appropriate for curing at ambient temperatures were employed to investigate the impacts of fly ash class C based geopolymer concrete. To react with fly ash class C, a combination of sodium hydroxide and sodium silicate alkaline activator was used. Fly ash class C was added as 20% of the total binder without using ordinary Portland cement. The durability of fly ash class C based geopolymer concrete in sulphate environments was tested. The changes in weight, length and compressive strength due to exposure in magnesium sulphate solution for different periods of time were determined. The test results demonstrate that fly ash class C based geopolymer concrete cured at normal temperatures has good resistance to sulphate attack. In general, inclusion of fly ash class C in geopolymer concrete improved strength and performed satisfactorily in sulphate environments when cured in ambient temperature.

Abstract

Geopolymer concrete has been developed as a replacement for conventional concrete with other pozzolan materials, which have a high silicate alumina content. Fly ash is a material that contains a high silicate alumina of 22%. The high content of Al and Si increases the compressive strength of concrete. High-calcium fly ash is abundantly found in Indonesia. However, it has not been widely used for industry or research, and this is due to the fast hardening time of concrete. Therefore, it has the potential to be developed. High-quality concrete has a low cement water factor that causes low workability in concrete. Self-compacting geopolymer concrete (SCGC) has been developed as a high-quality concrete innovation with high workability. Concrete is produced by using gravel, sand, fly ash, alkaline activator, and water materials. This study used 14 Molar levels of NaOH. The variations used were 0%, 3%, 5%, and 7% superplasticizers (SP) made from polycarboxylate. This study used a dry mixing method to overcome the setting time on concrete. The results show that the workability that can be achieved is 645mm, and the compressive strength achieved is 41.7 Mpa

Abstract

Concrete performances have weaknesses; one of those weaknesses is that it is significantly affected when put in a high sulfate and chloride environment. This study aims to investigate sulfate's effect on PCC concrete's performance. In this research, PCC concrete was immersed in water for 28 days and conducted after the casting. After being soaked in water, three immersed specimens were removed and immersed in magnesium sulfate solution for 24 days and 84 days, whereas three others were removed and immersed in natrium sulfate solution for 24 days and 84 days. The observation showed that PCC concrete's average compressive strength test with water immersion was 42.17 Mpa. It meets the SNI 2847:2019 Indonesian standard for sulfate classification S1. The specimens decreased to 30.74 Mpa after being soaked in the magnesium sulfate solution for 28 days and again reduced to 25.39 Mpa at 84 days. The average compressive strength of specimens bathed in the sodium sulfate solution for 28 days was 32.19 Mpa. It decreased to 28.03 Mpa at the age of 84 days. The results of this study show that the compressive strength of PCC concrete soaked in sodium sulfate meets the SNI 2847:2019 standard for sulfate classification S1, which is more than 28 Mpa. The compressive strength of PCC concrete immersed in magnesium sulfate for 1 month (28 days) is more than 28 MPa. It meets the standard as well. Yet, the compressive strength of PCC concrete soaked in magnesium sulfate for 3 months (84 days) does not meet the standard.

Abstract

Desa Wirotaman merupakan salah satu desa terdampak bencana gempa bumi yang terjadi pada April 2021 lalu yang berdampak pada runtuhnya beberapa bangunan dan terganggunya sistem distribusi air bersih pada beberapa lokasi. Padahal, banyak ditemukan sumber mata air di Desa ini yang seharusnya dapat memenuhi kebutuhan warganya. Namun fakta nya, perolehan sumber daya air di desa ini masih belum merata seluruhnya. Beberapa wilayah mengalami kendala air bersih sehingga warganya harus berjalan menuju sumber mata air sambil membawa jerigen-jerigen untuk kemudian dibawa ke rumah masing-masing. Untuk itu, tim abdimas melaksanakan pemasangan pompa hidram pada salah satu sumber mata air di lokasi yang sulit mengakses air bersih untuk memperpendek jarak sehingga air lebih mudah diakses oleh warga. Selain itu, dilakukan pula pengukuran GCP dan pengambilan data citra menggunakan drone. Dari kedua pengukuran ini akan didapat peta orthophoto yang dapat dijadikan acuan dalam perencanaan jalur perpipaan karena memuat data elevasi dan koordinat wilayah.
