The high volcanic activity of Mount Sinabung in recent years to cause an earthquake has greatly affected the lives of the people of North Sumatra. The people of North Sumatra have the Maimun Palace, a historic building designed to withstand earthquakes, before the rules and standards for earthquake-resistant buildings existed. This research was conducted on Jalan Brigjen Katamso, Medan Maimun District, Medan City. Structures are modeled into frames and 3D model. An analysis of structural irregularities and response spectra with SAP 2000 was performed. Maimun Palace is horizontally regular but vertically irregular, namely mass irregularity, vertical geometry, direction discontinuity in resisting horizontal forces. From the results of the SAP 2000 analysis, the structural reaction and boundary obtained are structure period 0.335 seconds (< 0.4676 seconds), basic shear force 1455,476 kN (> 80% Vstatic = 1324.7 kN), maximum deviation of 7.301 mm ( < 150 mm). Based on these parameters, it is concluded that Maimun Palace is safe against earthquakes.Keywords: Basic shear force, irregularity, structural periode, structural reaction, deviation

Abstract

Concrete is a material used in modern construction and is a very important component in the manufacture of structures. Concrete has advantages, but also disadvantages, namely low tensile strength. To increase the tensile strength of concrete, fibers are added to the mix. One of the efforts made to increase the tensile strength of concrete is the addition of fibers to the fiber-concrete mixture. The purpose of this study is to examine the compressive strength and tensile strength values in fiber concrete if added with variations in fiber addition. An innovation in increasing the value of mechanical quantities in concrete is the use of bent wire fibers as a mixture in fiber concrete. This material is taken from former pieces in construction projects to connect steel reinforcement with Sengkang reinforcement and is also widely found in building shops. The fibers were also analyzed for microstructure using SEM (Scanning Electron Microstructure) tools. The length of this bent wire fiber is 13 mm with a diameter of 0.82 mm and has a minimum tensile strength value of 334.5 MPa. The variations in the addition of these bent wire fibers are 0%, 3%, 6%, and 9% of the total weight of the steel fiber. The soaking life of concrete is 7 days, 14 days, and 28 days. The results of this study show that the more variations in the addition of bent wire fibers, the compressive strength value of concrete and the tensile strength value of concrete will also increase. It can be seen that fiber concrete with an immersion life of 28 days with a variation of 9% added bent wire fiber has a maximum compressive strength value of concrete which is 63,645 MPa and a maximum value of tensile strength of 3,294 MP.

Abstract

Concrete material is one of the most widely used construction materials in Indonesia due to its high compressive strength and adaptability to various construction needs. Despite its benefits, concrete has limitations, notably its weakness in tension and tendency to crack under tensile stress. This research focuses on High-Performance Concrete (HPC) with compressive strength exceeding 80 MPa, reinforced with 3D Dramix steel fibers to enhance both compressive and tensile strength. The study aimed to evaluate the compressive strength and splitting tensile strength of HPC mixed with varying percentages (0%, 3%, 6%, and 9%) of Dramix 3D steel fibers. Additionally, the methodology involved microstructure analysis using Scanning Electron Microscopy (SEM) and mechanical testing on HPC samples cured at 7, 14, and 28 days. Results indicate that the compressive strength reached a maximum of 94.776 MPa, and tensile strength reached 6.599 MPa with a 9% fiber addition at 28 days, highlighting the material's potential application in high-performance structural elements. The findings suggest that 3D Dramix steel fibers significantly enhance the mechanical properties of HPC, making it a viable option for durable construction.

Abstract

The utilization of waste as a substitute material for aggregate in paving blocks has become an effective and innovative option. One of the largest contributors to global plastic waste is Polyethylene Terephthalate (PET) bottles and High Density Polyethylene (HDPE) bottle caps, both of which are types of plastic that can be used in paving mixtures due to their strength and easy availability. This research aims to examine the effects of using plastic bottle waste and bottle cap waste as aggregate substitutes on the mechanical properties of paving blocks, including impact testing and cost analysis. The results of this study show that PET variations perform better than HDPE. A 5% PET plastic variation produced the highest compressive strength of 22.32 MPa, while the lowest compressive strength was recorded with a 15% HDPE variation at 14.62 MPa. In addition to mechanical performance, paving blocks with PET variations are capable of reducing up to 2.45 kg of plastic bottles per 1 m².The utilization of waste as a substitute material for aggregate in paving blocks has become an effective and innovative option.

Abstract

General Background: Structural design requires precise determination of loading, with wind load being a critical component that influences the safety and behavior of buildings. Specific Background: In Indonesia, wind load regulations have evolved significantly—from PPIUG 1983 to SNI 1727:2013 and the latest SNI 1727:2020—reflecting changes in building practices and meteorological understanding. Knowledge Gap: However, the comparative impact of these evolving standards on spatial truss structures remains insufficiently explored. Aims: This study investigates how the three standards affect wind load distribution and structural response in space trusses using ETABS software. Results: Findings reveal substantial differences, with SNI 1727:2020 producing the highest mid-span wind pressure (0.886 kN/m²), exceeding that of SNI 1727:2013 (0.546 kN/m²), due to the introduction of the elevation coefficient (Ke) and revisions in building categorization. Novelty: This research uniquely highlights how regulatory evolution introduces quantifiable changes in displacement, axial force behavior, and total structural weight. Implications: The study informs engineers and designers of the critical implications of standard selection, promoting better-informed structural safety and optimization decisions in modern Indonesian construction. Highlights: Highlights regulatory evolution from PPIUG 1983 to SNI 1727:2020. Shows impact of new wind pressure coefficient (Ke) on design results. Compares structural responses under different wind load standards. Keywords: Wind Load, Space Truss, Structural Analysis, Indonesian Standards, ETABS

Abstract

General Background: Long-span buildings are essential in accommodating wide, unobstructed interior spaces, commonly applied in structures such as stadiums and assembly halls. Specific Background: One effective structural system for such buildings is the space truss with barrel vault configurations, known for their strength and spatial efficiency. Knowledge Gap: However, limited comparative studies exist on the seismic performance and material efficiency of various barrel vault space truss models. Aims: This study aims to analyze and optimize seven barrel vault space truss models spanning 192 m by 120 m with a height of 50 m, focusing on earthquake load response and structural tonnage. Results: The analysis reveals that model 1 has the lowest base shear (V = 3142.50 kN) and structural tonnage, while model 6 exhibits the highest tonnage—62.24% heavier than model 1—and base shear of 4881.18 kN. Novelty: The study provides a comparative seismic performance assessment of large-span space truss models under identical geometric and loading conditions. Implications: These findings support the structural optimization of space trusses for earthquake-prone regions, offering practical insights for efficient and resilient long-span building design. Highlights: Highlights the efficiency of barrel vault space trusses in seismic conditions. Compares seven models to determine the most optimal structure. Emphasizes material savings through structural optimization. Keywords: Space Truss, Earthquake Load, Structural Analysis, Barrel Vault, Optimization

Abstract

Keamanan struktur jembatan sangat bergantung pada kemampuan gelagar (girder) dalam menahan beban rencana. Penelitian ini bertujuan untuk menganalisis kapasitas lentur dan geser jembatan pelat baja girder bentang 24 meter berdasarkan SNI 1729:2020, serta mengkaji pengaruh konfigurasi stiffener pada area tumpuan menggunakan pendekatan numerik. Metode penelitian dilakukan melalui perbandingan antara perhitungan analitis secara manual dengan pemodelan numerik menggunakan perangkat lunak SAP2000 dan metode elemen hingga (Finite Element Method/FEM). Hasil penelitian menunjukkan bahwa kapasitas lentur dan geser gelagar pelat baja berdasarkan analisis analitis memiliki kesesuaian yang sangat baik dengan hasil pemodelan SAP2000. Perbedaan nilai momen ultimit (Mu), momen nominal (Mn), dan gaya geser ultimit (Vu) antara kedua metode relatif kecil, sehingga struktur dinyatakan memenuhi kriteria kekuatan berdasarkan SNI 1729:2020. Selain itu, hasil analisis numerik menunjukkan bahwa konfigurasi jarak stiffener pada area bearing memberikan pengaruh signifikan terhadap performa mekanis struktur. Semakin rapat jarak stiffener, maka kekakuan struktur meningkat dan deformasi vertikal menurun. Hal ini ditunjukkan oleh penurunan lendutan maksimum dari 53,63 mm pada model tanpa stiffener menjadi 38,34 mm pada model dengan jarak stiffener 12,5 cm. Model dengan jarak stiffener 12,5 cm merupakan konfigurasi paling optimal karena menghasilkan deformasi terkecil dan mampu menurunkan tegangan Von Mises maksimum hingga 314,60 MPa, sehingga memberikan distribusi beban dan integritas struktural yang lebih baik pada area tumpuan.

Abstract

This study aims to evaluate the utilization of metal-coated plastic packaging waste (WMP) and eggshell powder (ESP) as partial substitution materials in the manufacture of environmentally friendly paving blocks. The method used is an experimental approach in the laboratory with variations of WMP of 5%, 10%, and 15% as aggregate substitutes, and ESP of 5% as cement substitutes. The test specimens were molded using a hydraulic press machine and tested based on SNI 03-0691-1996 standards for compressive strength, water absorption, resistance to sodium sulfate solution, and impact tests. The results showed that the combination of WMP and ESP was able to improve the mechanical performance of paving blocks, especially in the variations of WMP 10% and ESP 5% which produced optimal compressive strength and low water absorption. This study contributes to the development of sustainable construction materials and supports the sustainable development goals (SDGs).
