Abstract

Pada tanggal 28 September 2018, terjadi gempa bumi dengan kekuatan 7,4 SR pada kedalaman 10 km. Pusat gempa berada di 26 km utara Donggala dan 80 km barat laut kota Palu. Terjadinya gempa ini dipicu oleh aktivitas laut Koro Palu dengan mekanisme patahan. Ribuan bangunan dilaporkan mengalami kerusakan mulai dari kerusakan ringan hingga kerusakan parah, termasuk bangunan-bangunan sekolahan milik Muhammadiyah. Kajian ini bertujuan untuk melakukan penilaian terhadap bangunan sekolah yang didirikan oleh Muhammadiyah. Dalam kajian ini, penilaian tingkat kerusakan bangunan menggunakan metode yang dirilis oleh World Seismic Safety Initiative pada 2007. Penilaian dilakukan di 37 gedung sekolah yang terdiri dari 1 lantai hingga 2 lantai. Hasil analisis menunjukkan bahwa 90% bangunan dibangun tanpa analisis struktural yang benar dan tidak dirancang untuk tahan gempa. Selain itu, beberapa bangunan dikategorikan cukup tua dan tidak dilakukan perawatan secara intensif. Hasil kajian menunjukkan bahwa hanya satu bangunan yang termasuk dalam kategori rusak berat karena rusaknya fondasi. Sementara itu, bangunan lain mengalami kerusakan pada komponen non strukturalnya yang dikategorikan rusak sedang dan rusak ringan.Kata kunci : pasca gempa, penilaian gedung, Palu, analisis struktural

Abstract

Flexural strength is one of the mechanical properties of concrete that should be tested, especially for concrete that serves as a beam and is subjected to flexural loads. However, the assessment of flexural strength in concrete frequently relies solely on a mathematical approach that several previous researchers have found. Concrete structures continue to evolve, particularly in the use of more diverse and sustainable constituent materials. Meanwhile, the generated equations use conventional concrete without adding cementitious or replacement components. Therefore, it is necessary to investigate whether these equations can accurately predict the flexural strength of concrete with diverse constituent materials. This investigation was undertaken by reviewing 72 data sets derived from the experiment by previous researchers. Each set of test data will be compared to various formulas and will also be compared to the analysis performed using Response-2000. The results show that the correlation between Response-2000 and the experiment was 0.8207 with the linear regression equation y = 1.1326x + 1.0016. The flexural strength analysis using various approach formulas resulted in an average correlation R² of 0.8246, or 82.46% correlated to the results of the flexural strength of laboratory tests.

Abstract

Indonesia is one of the countries that has a fairly high seismic condition. This is because Indonesia is passed by the Pacific Ring of Fire, which brings together many world plates, so it is natural that many earthquakes occur in Indonesia. With a fairly high seismic condition, there is a need for vigilance and actions taken to overcome the situation. The infrastructure sector becomes an important spotlight when an earthquake occurs because casualties are often caused by structural failures that are not strong enough to withstand the earthquake load. This is similar to what happened in the earthquake in Cianjur in 2022, which claimed many lives due to the numerous structural failures in permanent residences. Therefore, this research was conducted to evaluate the permanent residences of the community related to the vulnerability that occurred due to the earthquake. Building vulnerability testing is carried out using the Incremental Dynamic Analysis (IDA) method with data from 11 earthquake records. Later, the building’s response to the earthquake load will be obtained, and the probability of damage seen from the vulnerability curve will be known. The five performance levels of the building are Operational Phase (OP), Immediate Occupancy (IO), Damage Control (DC), Life Safety (LS), and Collapse Prevention (CP).

Abstract

Self-compacting concrete (SCC) merupakan beton yang dapat mengalir dan memadat dengan berat sendirinya, sehingga dapat mempercepat dan mempermudah pengecoran dalam suatu pekerjaan proyek konstruksi. Tujuan penelitian ini adalah untuk mengetahui flowability dan kuat tarik self-compacting concrete dengan penambahan abu sekam padi sebagai pengganti sebagian agregat halus dan penambahan silica fume sebagai pengganti sebagaian semen. Abu sekam padi merupakan salah satu limbah hasil pertanian yang belum dimanfaatkan secara optimal, sehingga melalui penelitian ini diharapkan pemanfaatan abu sekam padi menjadi lebih efektif. Kadar silica fume yang digunakan sebesar 5% dari berat semen, sedangkan variasi abu sekam padi yang digunakan sebesar 20%, 40%, 60% dari berat agregat halus. Pengujian beton segar menggunakan metode slump flow, J-ring, L-box and V-funnel untuk mengukur kemampuan beton mengalir sendiri. Pengujian kuat tarik beton dilakukan pada umur 3 hari, 7 hari, 28 hari dengan benda uji berbentuk silinder ukuran 15 x 30 cm. Berdasarkan hasil penelitian didapat bahwa semakin tinggi kadar abu sekam padi yang digunakan maka kuat tarik mengalami penurunan. Kuat tarik optimal dimiliki oleh campuran abu sekam padi 20% dengan kuat tarik rata-rata sebesar 1,23 MPa pada umur 3 hari, 1,24 MPa pada umur 7 hari, 1,31 MPa pada umur 28 hari. Sedangkan melalui pengujian betonsegar menunjukkan bahwa abu sekam padi dapat digunakan sebagai bahan tampah untuk self-compacting concrete.

Abstract

This research showcased the use of leftover trash as a substitute for aggregate in mortar combined with saltwater. The raw waste materials underwent analysis using X-ray fluorescence (XRF) in order to determine the component materials and crystalline phases present. The choice of Portland composite cement (PCC) was made because of its durability in a hostile environment. Seawater is used to combat the water crisis and prevent corrosion, thanks to its exceptional resistance to corrosion. The attributes of mortar were assessed in terms of its fresh characteristics (slump and flow table) as well as its mechanical properties (compressive strength, split tensile strength, flexural strength, density, and shrinkage). The findings indicate that the dried mortar waste is suitable as a patch repair material for a substrate with a strength of 20 MPa, but only when utilized in a maximum quantity of 20% and with a water-to-cement ratio of 0.3. The repaired concrete with a strength of 25 MPa did not need any waste containment and had a maximum water-to-cement ratio (W/C) of 0.3, whether combined with saltwater or tap water. The possible role of the mortar containing the dried waste was to be the species for brick and other non-structural. Additionally, the use of an alternative cementitious substance is suggested to enhance the effectiveness of the patch repair material, particularly when paired with cathodic corrosion protection in damaged concrete

Abstract

The rapid expansion of the construction sector has escalated cement use, significantly impacting the environment due to CO2 emissions. Geopolymers are eco-friendly construction materials designed to reduce cement use and have the potential to be a patching material to rehabilitate concrete structures due to corrosion damage. Among these, pozzolanic materials like rice husk ash, rich in aluminosilicate, are abundant and suitable for geopolymer binders. This study explored the use of rice husk ash and alkali activators (NaOH/Na2SiO3), with different activator percentages (40%, 45%, and 50%), to evaluate their mechanical properties and potential applications as patch repair materials. This research involved formulating an optimal mix design through trial and error in a laboratory setting, followed by curing at 70 °C and testing at room temperature. XRF and SEM-EXD analyses were performed to determine the chemical composition and microstructure of the specimens. The activators, NaOH and Na2SiO3, were employed in a 1:3.5 ratio, with 14M molarity and 2% superplasticizer, to enhance workability. The test yielded the geopolymer mortar’s highest compressive strength of 8.14 MPa at a 40% activator variation. In comparison, the highest split tensile and flexural strengths were 2.50 MPa and 1.00 MPa, respectively, both at a 50% variation. These findings demonstrated the suitability of the mortar for patch repair on concrete substrates with compressive strengths below 8 MPa. The mechanical properties of the rice husk ash geopolymer mortar were influenced by the silica, calcium, and alkali activator content, affecting the mortar’s strength and density.
