Abstract

As the demand for bridge infrastructure grows, efficient and effective alternatives for bridge design and analysis are essential. One such case is the Tawaeli I Bridge in Palu, Central Sulawesi, which requires careful design due to the city’s location in a high-seismic zone. The Camelback Truss steel bridge is ideal for this area because of its ability to withstand extreme conditions and provide structural stability during earthquakes. The design analysis for this type of bridge was performed using the Struktur FEM software, which evaluates bending, compression, and tension members. This analysis was validated through manual calculations. The section capacities obtained are: stringers (main longitudinal girders) IWF 500.200.11.17; cross girders (transverse girders) IWF 800.400.18.34; bottom chords (side longitudinal girders) IWF 650.650.18.34; top chords (upper members) IWF 650.650.18.34; diagonal chords (diagonal members) IWF 650.350.14.24; vertical chords (vertical members) IWF 600.200.11.17; transverse bracing IWF 250.250.9.14; diagonal bracing (wind bracing) angle 250.25.25. The mid-span deflection is 75.704 mm, within the allowable deflection of 87.5 mm. The accuracy between the Struktur FEM analysis and manual calculations is 99.9%.

Abstract

According to ESDM, 215 ground motion events were reported during 2023. Landslides are natural phenomena that occur frequently and have a significant impact. Landslides also occur in road construction, such as the landslide on the Toboli - Kebun Kopi road section. There are two methods of dealing with landslides, namely preventive methods and curative methods. Preventive method is a method used to prevent landslides, while curative method is a method used to handle landslides that have occurred. On the Toboli - Kebun Kopi road section, landslides have occurred, therefore the countermeasure uses curative methods, one of which is a cantilever type retaining wall. The purpose of this research is to obtain the stability value of slope structure, and predict whether deformation occurs after countermeasures are taken. Based on the results of the analysis, the structural stability value is bolster: 2.850 > 2 (safe), shear: 2.268 > 1.5 (safe) and soil bearing capacity: 106 > 3 (safe). And the stability of slope after being given countermeasures using the finite element method with help of the plaxis program on saturated slopes: 1.60 and unsaturated slopes: 1.90. After given countermeasures deformation occurs on saturated slopes by 3.59 cm and unsaturated by 3.42 cm.

Abstract

At the moment, the cost of concrete is quickly increasing as the cost of cement and aggregates continues to rise. As a result, a replacement for fine aggregate as well as a substitute for cement is required to decrease the cost of concrete production. In general, concrete is composed of cement as a base material that is workable and satisfies specified performance, durability, and strength criteria, aggregate, and water. In the field of engineering constructions, reinforced high-strength concrete has a significant impact on development. Apart from its exceptional strength, this kind of concrete must exhibit workability, minimal shrinkage, release characteristics, and self-compaction. The authors of this research performed a literature review to explore high-quality concrete made using fly ash as a replacement for cement and fine particles. Fly Ash is a waste product or byproduct of the coal-fired power plant's combustion process. Fresh concrete made using fly ash as cement and fine aggregate has an average slump value of 90-200 mm. The compressive strength of concrete made with fly ash ranges between 35 and 60 MPa after a 28-day curing period. The optimal percentage of fly ash in high-strength concrete is between 10% and 30%.

Abstract

Inventory data and road conditions are the main road network data for measuring and monitoring road network conditions, making predictions of future conditions, and assisting in the strategic decision making process in road network management. This data is also the main data in general road network planning, programming and budgeting, research to evaluate the condition of road pavement to evaluate the condition of road pavement according to the level of damage so that later the budget can be determined. Data collection on road conditions uses a survey vehicle called Mata Garuda (MAGARU). The data obtained from MAGARU is road network data/RNI, pavement condition data/PCI and road unevenness data/IRI. Testing using the Benkelman Beam (BB) tool at 100 m intervals. Collecting traffic enumeration data uses CCTV equipment installed on the road section with an observation period of 7 x 24 hours. The results of the analysis showed that the proposed type of treatment was Preventive with an average value of 3.7, Minor Rehabilitation with an average value of 5.4 and Major Rehabilitation with a value of 8.8. For the PCI survey analysis, Preventive Treatment was obtained with an average value of 87.5, Minor Rehab with an average value of 65.3 and Major Rehab with an average value of 27.5. For the analysis of the deflection survey, a value of > 0.4 was obtained so the treatment was Major Rehab. The CESA4 value is 4,059 x 106 and the CESA5 value is 5,546 x 106. The results of pavement calculations show that Preventive Treatment uses Thin Layer Asphalt Concrete (LTBA), Minor Rehab uses Asphalt Concrete Wearing Course (AC-WC), Major Rehab uses Asphalt Concrete Wearing Course ( AC-WC), Asphalt Concrete Binder Course (AC-BC) and Asphalt Concrete Binder Course Leveling (AC-BC Lev).

Abstract

Dalam dunia konstruksi, Tanah berguna sebagai bahan dalam pekerjaan teknik sipil. Salah satunya pada konstruksi jalan raya. Stabilisasi konstruksi perkerasan secara langsung akan dipengaruhi oleh kemampuan tanah dasar dalam menerima dan meneruskan beban yang bekerja. Pada penelitian kali ini memakai tanah lempung sebagai objek penelitian dan bahan tambah yang digunakan yaitu Abu Sekam Padi dan Abu Kulit Kakao. Umumnya tanah lempung memiliki sifat palastisitas tinggi, volume akan berubah bila kadar air berubah. Sifat inilah yang dapat menimbulkan kerusakan pada konstruksi perkerasan seperti retaknya jalan, terangkatnya lapisan perkerasan, jalan bergelombang dan sebagainya. Oleh sebab itu, sifat tanah lempung yang kurang baik harus diperbaiki sebelum melaksanakan suatu konstruksi. Penelitian ini merupakan experimen yang dilakukan pada Laboratorium Teknik Sipil Universitas Bosowa. Dari hasil penelitian dengan 5% Abu Sekam Padi dengan variasi abu kulit kakao 5%, 10% dan 15% berturut-turut didapat hasil nilai kuat tekan sebesar 0.516 Kg/cm2, 0.636 Kg/cm2, dan 0.756 Kg/cm2.
