Abstract

This study investigates the differences in mechanical behavior and stress distribution between two types of bolted steel connections—splice and endplate joints—using the Finite Element Method (FEM). Numerical simulations were conducted with MIDAS FEA NX, employing SS400 structural steel and A325 high-strength bolts to model beam connections subjected to bending loads. The analysis focused on evaluating von Mises stress distribution, deformation behavior, and load transfer mechanisms. Results showed that the endplate connection exhibited higher stiffness —approximately 5% less deflection than the splice connection —but also experienced 9.6% higher local stresses concentrated near the weld and in the outer bolt regions. Conversely, the splice connection exhibited a more uniform stress distribution and greater ductility, enabling controlled local yielding and improved energy dissipation. FEM predictions closely matched analytical beam theory with less than 5% deviation, confirming the accuracy of the numerical model. The findings suggest that endplate joints are suitable for rigid moment-resisting frames, while splice connections are preferable for applications requiring flexibility, fatigue resistance, and ease of assembly.

Abstract

Increasing exposure of infrastructure systems to extreme hazards, aging effects, and climate-induced uncertainties has revealed fundamental limitations of conventional strength- and safety-oriented design approaches. Structural performance can no longer be evaluated solely in terms of damage prevention, but must also account for functionality loss, system interdependencies, and recovery capacity. This study aims to reengineer the concept of structural resilience by developing a multiscale framework that integrates resilience explicitly into performance-based infrastructure design. The research adopts an analytical and framework-oriented methodology, combining critical synthesis of performance-based design theories, structural resilience metrics, and systems engineering concepts. Multiscale linkages are established among component-level behavior, system-level functionality, and network-level performance, with explicit consideration of temporal recovery processes. The results demonstrate that resilience is an emergent and time-dependent system property that cannot be inferred directly from component-level performance indicators. Local strengthening strategies are shown to yield limited resilience gains unless supported by system redundancy, connectivity, and recovery-oriented design. The proposed framework reveals hidden vulnerabilities and recovery bottlenecks that remain unaddressed in conventional performance-based approaches. The study concludes that effective resilience-oriented infrastructure design requires a paradigm shift toward multiscale, system-aware, and recovery-informed performance objectives. Embedding these principles into performance-based design provides a robust foundation for enhancing infrastructure reliability, functionality, and societal resilience under extreme and uncertain conditions.

Abstract

Penelitian ini mengkaji perilaku lendutan balok baja melalui pendekatan Metode Elemen Hingga (MEH) dan pengujian eksperimental untuk memperoleh kurva beban–lendutan yang akurat. Tujuan utama penelitian ini adalah membandingkan respons struktural balok baja tipe IWF terhadap pembebanan lentur melalui dua pendekatan berbeda, yaitu simulasi numerik dan pengujian laboratorium. Analisis dilakukan pada balok baja dengan beban terpusat (three-point bending) untuk mengevaluasi kesesuaian hasil prediksi numerik terhadap fenomena fisik yang terjadi. Metode Elemen Hingga digunakan untuk memodelkan balok secara ideal dengan asumsi material elastis linier serta kondisi batas yang terkontrol. Sebaliknya, pengujian eksperimental dilakukan menggunakan Universal Testing Machine (UTM) dengan pemantauan lendutan melalui sensor LVDT. Hasil penelitian menunjukkan bahwa kurva beban–lendutan dari MEH dan hasil uji laboratorium memiliki kecocokan pola yang baik, terutama pada wilayah elastis. Perbedaan nilai lendutan maksimum sekitar 5–10% teridentifikasi sebagai akibat dari variasi sifat material aktual, imperfection struktural, serta deviasi kondisi tumpuan. Penelitian ini menegaskan bahwa MEH merupakan alat prediksi yang efektif dalam analisis perilaku lentur balok baja, namun tetap memerlukan validasi eksperimental untuk memastikan akurasi hasil perhitungan. Temuan ini bermanfaat dalam perencanaan struktur baja, khususnya untuk memastikan keselamatan dan efisiensi desain.

Abstract

Material selection in the construction industry is a strategic decision that affects the cost efficiency, durability, and sustainability of a project. This study applies the Analytic Hierarchy Process (AHP) method to determine the best construction material based on four main criteria: mechanical strength, environmental resistance, cost efficiency, and environmental sustainability. The hierarchical structure is built with three levels: material selection objectives, evaluation criteria, and compared material alternatives—namely structural steel, cross-laminated timber (CLT), and reinforced concrete. The assessment uses the Saaty scale (1–9), then the matrix is normalized to obtain priority weights. Consistency tests are carried out by calculating the maximum eigenvalue (λmax), Consistency Index (CI), and Consistency Ratio (CR). The results show that structural steel has the highest weight (0.4888093), making it the best choice compared to CLT and reinforced concrete. This study confirms that the AHP method is able to reduce subjectivity in decision making with a data-driven approach. Integration with technologies such as Building Information Modeling (BIM) and Artificial Intelligence (AI) can improve the accuracy of the analysis. Thus, this method can be a solution in selecting construction materials that are more systematic and sustainable.

Abstract

Reliable irrigation water supply is a crucial factor in supporting sustainable agricultural development, particularly in watershed areas where river discharge fluctuates significantly throughout the year. In many cases, excess water during the rainy season cannot be effectively utilized, while water shortages occur during the dry season, limiting agricultural productivity. This study aims to develop an irrigation dam planning scheme as a water storage and regulation structure capable of ensuring continuous irrigation water availability. The analysis includes hydrological assessment to determine water availability potential, calculation of irrigation water demand based on land characteristics and cropping patterns, and reservoir capacity planning in accordance with local topographic conditions. In addition, the technical design of the dam is evaluated through dimensional planning and stability analysis against sliding, overturning, and slope failure. The results indicate that the proposed dam has sufficient storage capacity to meet irrigation water demands and satisfies structural safety requirements. The implementation of this dam planning is expected to improve water resource utilization efficiency and strengthen agricultural sustainability within the studied watershed area.

Abstract

The construction of a multi-story parking building in densely populated areas such as Plaza 6 Pondok Indah is a response to limited land availability and the increasing demand for parking facilities. This project employs modern construction methods, such as minipile foundations and precast structural systems, to accelerate project timelines and maintain on-site efficiency. This study aims to directly examine the implementation process and structural systems used on-site, as well as evaluate their effectiveness in terms of technical performance and construction time. Data were collected through direct observation at the project site, technical documentation, and informal discussions with project personnel. Emphasis was placed on the stages of foundation work, substructure components such as pile caps and tie beams, and the installation of precast components on each floor. Additionally, the installation of steel structures was an essential aspect of this study. Observations revealed that the use of precast floor slabs significantly reduced construction time by minimizing the need for formwork and scaffolding. The steel frame system provided advantages in installation flexibility and faster on-site mobilization. The selection of minipiles as the foundation type was also appropriate for the limited land space and moderate soil bearing capacity. Overall, the construction methods used in this project offered substantial benefits in terms of time and on-site efficiency. This study may serve as an initial reference for similar projects, particularly in utilizing a combination of steel structures, precast elements, and deep foundations.
