Abstract

Clay soil has low load-bearing capacity. One method to improve this issue is by mixing chemical additives, such as silica fume and red brick powder, into the clay soil as adhesive media that can fill the soil's pores, compacting and forming a solid mass. This study aims to determine the unconfined compressive strength and shear strength of clay soil after adding silica fume and red brick powder. The method involves testing unconfined compressive and shear strength using 9% red brick powder by soil weight, along with silica fume added in varying amounts of 5%, 10%, and 15%. Three samples are prepared for the original soil and each composition used. The unconfined compressive strength of the original soil increased by 48.2% with the addition of 9% red brick powder, while each 5% addition of silica fume raised the compressive strength by an average of 3.1%. Similarly, shear strength increased by 33.5% in the original soil with 9% red brick powder, while each 5% silica fume addition improved it by an average of 5.4%. The addition of red brick powder and silica fume can effectively increase the compressive and shear strength of clay soil.

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

The bridge, a structural construction used to cross gaps or obstacles like rivers, railroads, or highways, is essential in infrastructure. Replacing Tawaeli I Bridge is part of the government’s initiative to improve road and bridge infrastructure in Indonesia. Tawaeli I Bridge has nearly reached its planned lifespan and thus requires replacement. The current concrete bridge design includes piers within the river flow, which creates issues, especially during the rainy season when rising water levels and carried debris risk damaging the piers. This study focuses on designing a replacement for Tawaeli I with an upper arch bridge structure using a Steel Box Through Arch Bridge system. The new bridge, spanning 80 meters in length and 10 meters in width, is designed without piers in the river, allowing unobstructed flow. It includes longitudinal IWF 500.200.10.16 girders, transverse IWF 900.500.24.36 girders, D 55 mm freyssinet hangers, an arch Box 1100.1000.50.50, and tension Box 1000.900.50.50. This design uses FEM structural software to analyze the structure and internal forces.

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.

Abstract

Soil is the most widely used material in the construction of a construction. The development of buildings is currently experiencing a very rapid increase so that the carrying capacity of the soil must be considered but not all the carrying capacity of the soil meets the requirements, such as the carrying capacity of clay soils whose soil types are very fine grained so that the layers of the soil are very soft and cohesive. The soil needs to be stabilized. In this study, gypsum and white cement were used to stabilize the waste. This study aims to determine the value of the free compressive strength of silty clay stabilized with 2% gypsum and varied with white cement to determine the appropriate material composition to increase the bearing capacity of the soil. The percentage of stabilizing material used in this study was 2% gypsum respectively, then varied with white cement: 4%, 8%, 12%. The results of the free compressive strength study obtained the maximum value at the composition of the mixture of 2% gypsum + 8% white cement. that is equal to 0.959 kg/cm²..
