Salah satu upaya mengoptimalkan kelebihan struktur baja adalah dengan menggunakan konfigurasi Sistem Rangka Berpengaku Eksentrik (SRBE) sebagai sistem rangka struktur. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan bresing eksentrik terhadap perilaku struktur dan membandingkan perilaku struktur SRPMK dan SRBE terhadap beban gempa. Dalam studi ini didesain sebuah portal baja beraturan menggunakan bresing tipe D dengan jumlah lantai 10. Perencanaan didasarkan pada SNI 03-1729- 2002 dan SNI 03-1726-2003. Sebagai pembanding turut didesain gedung yang sama namun tanpa menggunakan bresing agar dapat dilihat pengaruh penambahan bresing eksentrik terhadap struktur tersebut ketika bekerja beban gempa. Hasil analisis menunjukkan bahwa SRPMK dan SRBE memiliki pola mode shape yang hampir sama. Penambahan bresing secara nyata dapat meningkatkan kapasitas struktur terhadap beban lateral secara umum sebesar 28,317% pada sumbu X dan 20,133% pada sumbu Y. Struktur SRBE memiliki kekakuan elastik dan pasca-elastik serta mekanisme pelelehan yang lebih baik dibandingkan struktur SRPMK.Kata Kunci : Komparasi, Perilaku, SRPMK, SRBE

Structural degradation caused by sudden damaging extreme events (e.g. earthquake) has significant impact on residual life of bridges and ultimately the collapse of bridges. This paper presents a reliability-based approach of a bridge subjected to shock degradation caused by earthquake events. In particular, this study develops a numerical procedure for assessing time dependent probability of failure to estimate the residual life a bridge. Key factors that govern the residual life of a bridge (e.g., damage size caused by earthquake shocks and loss of initial structural capacity) were investigated. The results of study show that both damage size caused by earthquake shocks and loss of initial structural capacity are key factors that govern residual life of a bridge. Keywords: residual life, earthquake, shock degradation, bridge.

Bridges are a critical part of transport infrastructure networks for social activities and economics of human life. Dynamic analysis of bridge is very important to perform in order to ensure the ability of the bridge to withstand loads and maintain the sustainability of transport infrastructure. This paper presents a methodological framework for monitoring dynamic behavior of the bridge (e.g., natural frequencies, displacement time history) by using civil engineering micro-tremor technique and numerical modeling. The study was conducted at the Alue Raya Bridge located in Lhokseumawe City, Aceh Province, Indonesia. To capture the dynamic behavior of the bridge under traffic loading, the micro-tremor techniques, e.g., Short Period Seismograph (SPS) sensor was placed underneath the bridge at the mid span of the bridge girder. The obtained vibration data were processed using Geopsy software. A three dimensional (3D) model of the bridge was then developed by using CSI Bridge software. The modal analysis was conducted to obtain the modal natural frequencies of the bridge due to traffic loads. The natural frequency measurements using SPS were compared with the simulation results. Through analyzing the measured results, it was found that the natural frequency of the bridge is around 4,3275 Hz which is very close to those obtained from numerical modeling using CSI bridge software. The measured maximum vertical displacement of the bridge girders is below 5mm under normal traffic condition which is under the allowable serviceability limit state requirements of the bridge. The outcomes of this study could have the potential to enable maintenance and capital works decisions which are an important component of the sustainability of transport infrastructure.

Aceh is one of the most earthquake-prone regions in Indonesia. It is, therefore, essential to design seismic resistance structures according to applicable standards. To reduce damage to building structures, the Indonesian government has updated the seismic-resistant design code for building and non-building structures. The seismic resistant design standard has been updated from SNI 03-1726-2012 to SNI 03-1726-2019 due to a significant change in spectrum response data. The purpose of this study was to evaluate and compare the impacts on the seismic base shear and the cross-sectional area of columns, beams, and tie beams of buildings in 23 regencies in Aceh Province based on SNI 03-1726-2012 and SNI 03-1726-2019. A typical five-story office building with medium-type soil is used in the study. For structural analysis, a particular moment-resistant frame was considered. The determination of the design response spectra is carried out by using coordinates and soil types through the website “indo spectra”. The method used is spectrum response analysis. Some different requirements in the two standards include the spectrum response curve, mass participation, and dynamic base shear. The study’s results revealed that the dynamic base shear in Sabang City had grown by 192.05 percent. Aceh Barat Daya Regency was observed to have the smallest increase in dynamic base shear, which was only 8.16 percent. The required cross-sectional area of structural columns, beams, and tie beams in Sabang City increased by 96%, 40%, and 44.44%, respectively; in the meantime, the required cross-sectional area of columns, beams, and tie beams in several regencies in Aceh province remained unchanged.

Dari hasil penelitian dengan campuran ijuk beberapa variasi yaitu tanah asli, 0.2% ijuk, 0.3% ijuk, 0.4% ijuk dan 0.5% ijuk terlihat bahwa dengan adanya penambahan ijuk mampu meningkatkan kepadatan kering tanah dan meningkat pula kadar air optimum yang diperlukan untuk mencapai kepadatan kering maksimum. Pada pemadatan tanah asli nilai kepadatan kering maksimum (Î³d max) 1.532 gr/cm3 dan kadar air optimum (Wopt) 20.20%, pada pemadatan 0.2% ijuk didapat kepadatan kering (Î³d max) 1.570% dan kadar air optimum (Wopt) 21,20%, pada pemadatan tanah asli ditambah 0.3% ijuk nilai kepadatan kering maksimum meningkat (Î³d max) yaitu 1,580 gr/cm3 dan kadar air optimum (Ï‰opt) 21,60 %. pemadatan tanah asli yang ditambah 0.4% ijuk nilai kepadatan kering maksimum (Î³d max) yaitu 1,585 gr/cm3 dan kadar air optimum (Ï‰opt) 21,90 %, dan pemadatan tanah asli yang ditambah 0.5% nilai kepadatan kering maksimum (Î³d max) yaitu 1,590 gr/cm3 dan kadar air optimum (Ï‰opt) 22.00 %. Dari berapa-berapa variasi campuran ijuk nilai kepadatan kering maksimum dan kadar air optimum tertinggi pada campuran ijuk 0.5% dan semakin besar nilai kepadatan kering maksimum maka tanah tersebut akan semakin rapat. Dengan demikian dapat disimpulkan bahwa pemadatan yang ditambah ijuk nilai kepadatan kering maksimum dan kadar air optimum meningkat dibangdingkan dengan tanah asli tanpa ada campuran ijuk. Hal ini disebabkan karena ijuk mampu mengikat antar partikel tanah sehingga pori-pori tanah tambah rapat.

High-volume fly ash (HFVA) in cement mortar has gained attention due to its potential to reduce environmental impact and enhance sustainability. However, HVFA mortar often exhibits reduced initial compressive strength compared to conventional mortars. Incorporating carbon nanotubes (CNT) and Graphene oxide (GO) has been shown to enhance the mechanical properties and microstructure of the mortar, which can overcome the shortcomings of HVFA. This study investigates the effect of CNT and GO on compressive strength and cement hydration of HVFA mortar. This study used fly ash as a 60% cement replacement, with 0.01% CNT and GO contents of 0.01%, 0.02%, 0.03%, 0.04%, and 0.05%. Compressive strength tests were performed at 3, 7, and 28 days of curing. The results showed that adding CNT and GO improved the compressive strength by 15.4% over the control mortar at 0.01% CNT and 0.03% GO. Most importantly, incorporating CNT and GO mitigated the typical reduction in initial compressive strength, with around a 15% increase observed at 3 and 7 days compared to the control mortar. The cement hydration characteristics were analyzed using X-ray diffraction (XRD), which revealed the presence of various crystallization phases, including calcium silicate hydrate (C-S-H), calcium aluminate silicate hydrate (C-A-S-H), quartz, portlandite, calcium carbonate, and ettringite. Adding CNT and GO to HVFA mortar significantly enhances its mechanical properties. It promotes the formation of complete chemical bonds in the cement hydration process, improving the mortar's overall performance.

Carbon Nanotubes (CNTs) are cylindrical nanostructures with exceptional mechanical strength, high electrical conductivity, and excellent heat transfer capabilities, making them a promising additive in asphalt mixtures. This study investigates the effect of CNTs on the Marshall parameters of Asphalt Concrete-Wearing Course (AC-WC) mixtures using 60/70 penetration asphalt. CNTs were added to asphalt at 60°C, followed by coarse and fine aggregates preheated to 150°C. Marshall parameter tests were conducted on the samples, and the results showed a significant increase in stability compared to conventional asphalt. Asphalt stability increased by 9%, with the highest value obtained at a CNT concentration of 0.015%, reaching 2177.83 kg. The optimal stability was achieved at a CNT concentration of 0.015%. This study demonstrates that CNTs can be effectively utilized to enhance the performance of AC-WC asphalt mixtures. The flow values decreased as the CNT content increased because CNTs make the asphalt mixture stiffer, improving temperature resistance.
