Interoperability in the context of Building Information Modeling (BIM) refers to the ability of different systems, software, and platforms to collaborate and share BIM information effectively. This enables professionals in the construction industry to work together more efficiently and minimize the risk of data loss or communication errors. Effective BIM interoperability is a critical aspect of the success of BIM implementation in construction projects, from the design process to on-site construction. One phase in BIM is the analysis and design of structures. This research addresses the challenges that arise in implementing BIM interoperability between architectural models and analytical models in multi-story buildings. The study was conducted by simulating reinforced concrete and steel multi-story building models, and obtaining structural element designs using ETABS and Revit software in standardized formats. The simulation results are presented in a workflow that identifies the dominant factors in the interoperability issues of each software. The availability of add-ons or plugins between software is a key factor leading to inconsistencies in data and coordinates, as well as discrepancies in the design results from the analytical model to the architectural model in the process of creating shop drawings.

Brick walls in portal structures are often considered non-structural components or parts of the architecture; consequently, the influence of the brick walls' strength and stiffness is often not considered in building planning. In reality, brick walls have a certain value of strength and stiffness in resisting lateral loads. In reinforced concrete buildings, the portal structure is filled with solid brick walls and brick walls with openings (holes) that serve as spaces for installing windows, doors, ventilation, and so on. This study aims to analyze the influence of the opening area on the lateral performance of reinforced concrete portals under cyclic loading. This study was conducted by comparing six specimen models, namely reinforced concrete portal structures with full walls (F-O-0), reinforced concrete portal structures with an opening area in the wall of 15% (F-O-15), 25% (F-O-25), 40% (F-O-40), 55% (F-O-55), and reinforced concrete portal structures without walls. (F-O-100). The research was conducted numerically using the ATENA V5.9.0 software (Demo Version). The outputs obtained with the help of the ATENA software that will be compared are the load-displacement hysteresis curves and the effect of the opening area on the wall. From the analysis results, it can be concluded that there is a decrease in energy dissipation as the opening area on the infill wall increases.

Setiap struktur yang menerima beban gempa akan memunculkan suatu perilaku atau respons khusus disebut respons seismik. Respons ini umumnya diidentifikasi dengan bantuan software elemen hingga, namun seiring dengan berkembangnya teknologi, para peneliti telah mengembangkan sebuah metode prediksi yang berdasarkan konsep kecerdasan buatan yaitu metode Jaringan Saraf Tiruan (JST). Penelitian ini berfokus pada penentuan akurasi metode JST dalam memprediksi nilai respons seismik gedung bertingkat pada beberapa lokasi di Indonesia. Model struktur yang digunakan adalah gedung bertingkat beton bertulang dengan 15 lantai dan respons seismik model tersebut dianalisis pada 3 jenis tanah di 34 ibukota provisi di seluruh Indonesia. Data hasil analisis kemudian digunakan untuk pengolahan data pada model JST menggunakan software MATLAB. Model JST yang digunakan pada penelitian ini terdiri dari 3 lapisan yaitu input layer, hidden (15 neuron) dan output layer. Lapisan input layer terdiri dari data geometri gedung, kondisi tanah dan parameter gempa lokasi tinjauan sedangkan output layer terdiri dari nilai perpindahan, kecepatan dan percepatan pusat lantai. Setelah 295 kali iterasi, model JST dapat memprediksi nilai respons seismik gedung pada 34 lokasi tinjauan dengan nilai rata – rata keseluruhan mean squared error (MSE) sebesar 1,95x10-5 dan nilai koefisien determinasi (R2) keseluruhan sebesar 99,96%. Hasil parameter akurasi ini (MSE dan R2) menunjukkan bahwa model JST telah berhasil memprediksi nilai respons seismik gedung bertingkat dengan akurat dan dapat dikembangkan pada kasus – kasus struktur tahan gempa lainnya.

The rising demand for concrete in the building sector has resulted in the exhaustion of natural sand and freshwater supplies, leading to the pursuit of sustainable substitutes. Coastal areas have plentiful ferronickel slag (SL) and seawater (SW), which can be used to manufacture concrete. Nevertheless, the possibility of corrosion to steel reinforcement raises concerns that require further research. This investigation examines the mechanical and durability performance of concrete that incorporates SL as a partial replacement for fine aggregate and SW as a mixing component. The objective is to optimize SL content to improve compressive strength, resistance to chloride ions, and overall durability. Experimental results show that replacing 25% of the aggregate with SL yields the best combination of workability, strength, and durability, significantly enhancing compressive strength, decreasing porosity, and lessening chloride ion penetration, as evidenced by the Rapid Chloride Penetration Test (RCPT). Although seawater promotes early-age hydration and strength development, its extended use slightly diminishes compressive strength due to salt-induced micro-cracking. However, SL counters these effects, making SW–SL mixture a feasible and sustainable option for concrete production in coastal and resource-limited areas. A significant relationship between RCPT and compressive strength underscores the important role of SL in densifying the matrix and improving impermeability. The concrete mixture with 25% SL exhibits the lowest abrasion weight loss at 28 and 120 days, showing improved durability. This study highlights the potential of using SL and seawater to create eco-friendly and high-performance concrete for harsh environments.

Studi ini menjelaskan tentang pengaruh dinding bata terhadap kapasitas seismik gedung beton bertulang. Di kota Padang, dinding bata digunakan sebagai dinding non struktural pada sebagian besar gedung beton bertulang. Dalam hal ini, kontribusi dinding bata terhadap kinerja struktur gedung bertulang dianalisis. Bangunan beton bertulang sepuluh lantai dipilih sebagai model dalam penelitian ini yang bertujuan untuk mengetahui kapasitas seismik dan keamanan gedung ditinjau dari perpindahan, drift rasio, dan gaya geser dasar. Untuk mengevaluasi kapasitas seismik gedung beton bertulang digunakan 2 (dua) model. Bangunan dianalisis dan dibandingkan antara bangunan beton bertulang dengan dan tanpa dinding bata. Pemodelan dianalisa dengan menggunakan Push Over Analysis dengan menggunakan software yang disebut Struktural Earthquake Response Analysis 3D (STERA 3D), Analisis Pushover dilakukan dengan menggunakan distribusi beban UBC. Hasil analisis menunjukkan bahwa dinding dalam rangka beton bertulang dapat meningkatkan gaya geser dasar sekitar 38% dan 25% pada arah X dan Y struktur dibandingkan dengan rangka beton bertulang tanpa dinding bata, dinding bata juga dapat meningkatkan titik kinerja dalam arah X dan Y struktur masing-masing sebesar 45% dan 32%. Dinding bata dapat mengurangi kerusakan pada komponen struktural. Dapat disimpulkan bahwa penggunaan dinding bata dapat memberikan peningkatan terhadap kapasitas seismik bangunan beton bertulang secara signifikan.

Indonesia is a country that has a very high level of seismicity. It is necessary to plan a building structure that can withstand the earthquake load. Indonesia has adopted guidelines on earthquake resistance planning procedures for buildings and non-buildings. This guideline uses the Performance-Based Seismic Design (PBSD) concept. Performance-Based Plastic Design (PBPD) is a structural analysis with the concept of energy methods which was initially used on steel structures. For reinforced concrete structures this method can also be used using the C2 coefficient. To determine the performance level of structures designed using the Performance-Based Plastic Design method, an analysis of the five-story reinforced concrete structure was carried out. Next, the structure will be analyzed using pushover loads. From the structural performance analysis, the structural ductility value based on Performance-Based Plastic Design (PBPD) was 3.014. The performance level is based on the capacity spectrum at the immediate occupancy level.
