Abstract

Penggunaan sekrup sebagai pengencang sambungan momen pada struktur baja ringan umum dilakukan terutama untuk konstruksi atap. Berbeda dengan baut, mekanisme tumpu pada sekrup dapat disertai pula dengan mekanisme tarik yang menyebabkan sekrup tertarik keluar (pull-out) dari bidang sambungan, mengingat sekrup tidak menggunakan mur. Analisis desain yang disertai dengan kegiatan eksperimental berikut akan memaparkan tentang perilaku dan bentuk kehancuran (failure mode) pada sambungan momen struktur baja ringan yang menggunakan sekrup. Hasil eksperimental menunjukkan bahwa sebagian besar sekrup mengalami rotasi dan tertarik keluar bidang sambungan (pull-out) sehingga dapat menurunkan kekuatan sambungan. Diketahui pula bahwa sekrup yang memiliki eksentrisitas besar terhadap pusat sambungan dan berlokasi dekat dengan beban, akan berpotensi putus akibat besarnya gaya geser yang diterima.

Abstract

Menurut AISC, kekuatan batas leleh lokal badan pada balok WF yang diakibatkan beban terpusat, dipengaruhi oleh panjang tumpu N dari pelat landasan, bukan lebar B. Beban terpusat tersebut didistribusikan ke badan balok dengan asumsi kemiringan sebesar 1: 2.5. Penelitian ini bertujuan untuk meninjau kemungkinan lebar pelat landasan B berpengaruh terhadap peningkatan kekuatan leleh lokal badan, serta asumsi kemiringan distribusi beban 1: 2.5 dapat dioptimalkan lebih lanjut. Metode penelitian dilakukan secara simulasi numerik dengan menggunakan software analisis elemen hingga (FEA), yang memodelkan baja WF di bawah pelat landasan sebagai elemen solid. Hasil FEA menunjukkan bahwa lebar B berpengaruh terhadap kekuatan leleh lokal badan, tetapi tidak signifikan. Distribusi beban juga dapat diusulkan dengan kemiringan 1:3.

Abstract

Innovations in modern building design encourage the integration of utility systems, such as rainwater drainage, into structural elements to improve space efficiency and aesthetics. This study aims to analyze the effect of embedding PVC (pralon) pipes as internal drainage channels on the strength and efficiency of reinforced concrete columns. A numerical analysis was carried out using the spColumn software on columns with dimensions of 350 × 600 mm, with variations in the number of 4-inch pipes (zero, one, two, and three). The results show that installing one, two, and three pipes gradually reduced the maximum compressive capacity of the column from 4100 kN to 3930 kN, 3790 kN, and 3650 kN, respectively. Despite this reduction, all column configurations were proven to be safe for sustaining the planned ultimate load of 368.72 kN. Interestingly, the structural–material efficiency of the column increased by up to 4.2% in the three-pipe configuration, as the reduction in concrete volume outweighed the decrease in capacity. It is concluded that the integration of PVC drainage pipes into columns offers a structurally safe, functional, and more material-efficient solution. These findings highlight the potential to reduce the need for external drainage channels, thereby improving spatial efficiency and lowering construction costs. Furthermore, integrating the drainage system into columns allows for cleaner, more minimalist façade designs without conventional piping interruptions, ultimately enhancing the aesthetic value and architectural competitiveness of the building.

Abstract

Construction sequence mismatches in stairwells often necessitate connecting stair slabs to the primary structure after it has already been erected. One practical on-site solution is the use of chemical anchors on the landing beam (edge beam), which interacts with the existing column. This study compares two behavioral schemes: (i) free-standing, where the stair slab spans between floor slabs without relying on the landing beam–column system; and (ii) bearing, where the slab edge rests on the landing beam anchored to the column. Numerical modeling was conducted using SAP2000, employing shell elements for the stair slab and link elements to represent joint stiffness. Gravity loads were defined according to SNI 1727:2020, while flexural–shear capacity evaluations of the slab followed SNI 2847:2019. The observed outputs included bending moment M11, shear V13, service deflection, link reactions, and local forces on the landing beam and column at the drilling zone. Comparative results show that the free-standing scheme reduces force transfer to the column but increases the demand on the stair slab; conversely, the bearing scheme decreases deflection and slab bending moments but raises anchor reactions and local column forces. In the case study, the design flexural capacity φMn of the slab approached but slightly fell below the demand Mu, while the serviceability deflection limit was satisfied. Therefore, the recommendation is conditional: the free-standing scheme is feasible if φMn ≥ Mu and deflection requirements are met; otherwise, slab strengthening or a shift to the bearing scheme with adequate anchor design is required. These findings provide a practical decision-making basis for projects involving non-monolithic stair connections.

Abstract

Formwork removal is a critical stage in reinforced concrete construction as it is directly related to quality, safety, and efficiency. In practice, this process often relies solely on the concrete age in days, without verification of the actual compressive strength, which may lead to cracking, excessive deflection, or even permanent damage. This study aims to analyze the relationship between the development of concrete compressive strength and the capacity of primary structural elements—columns, beams, and slabs—in carrying construction loads, as a basis for determining the safe timing of formwork removal. The method employed consists of a literature review and conceptual analysis based on SNI 2847:2019, ACI 347.2-17, and compressive strength test data at ages 1–28 days. Axial and flexural capacities of the elements were compared with construction loads in accordance with SNI 1727:2020, along with an evaluation of service deflections. The analysis results indicate that columns can be safely stripped at 1 day, as their axial capacity significantly exceeds the applied loads, whereas slabs and long-span beams are safe to dismantle after 14 days, when concrete achieves at least 70% of f’c. These findings confirm that concrete age alone cannot serve as the sole reference; verification of actual strength is crucial to ensure that formwork removal is carried out safely and efficiently.

Kata kunci: bekisting permanen, ferosemen berlapis seng, mortar, pelat lantai Abstract Conventional concrete slab construction generally requires temporary formwork, is time-consuming, and produces waste. In the context of faster, more efficient, and environmentally friendly construction needs, construction floor slabs require structural innovation materials that can integrate the functions of formwork and structure. The purpose of this study was to evaluate the mechanical performance of zinc-coated ferrocement plates, so that their potential as permanent formwork can be known. This study uses an experimental approach followed by construction trial activities in a multi-storey house. The zinc-coated ferrocement plate test specimens were made with a length of 55 cm, a width of 20 cm, a height of 4 cm, and using mortar with a cement-sand ratio of 1:3. From the flexural test, the results showed that the zinc-coated ferrocement plate could be loaded up to 365 kgf with a deflection of 0.65 mm. The results of this study are expected to be useful in contributing to innovations in efficient and environmentally friendly floor slab materials.

Abstract

Concrete compressive strength is a fundamental parameter for evaluating the performance of concrete structures. Although destructive testing using a Compression Testing Machine (CTM) is considered the most accurate method, its limited applicability to existing structures has led to the use of non-destructive methods, such as the rebound hammer test. However, rebound hammer results often deviate from CTM measurements, raising concerns regarding their reliability. This study examines the impact of rebound hammer test point location on the variability and accuracy of estimated concrete compressive strength, and assesses its agreement with destructive test results. A quantitative laboratory experimental program was conducted using concrete with a target strength of 15 MPa. Five cylindrical and five cubic specimens were tested at 28 days. Rebound hammer tests were performed on top, bottom, and side surfaces in accordance with ASTM C805, followed by destructive compressive strength testing using CTM based on ASTM C39. The results show that test point location systematically influences rebound hammer outcomes. Bottom test points produce the highest estimated strengths and the largest deviations from CTM results, whereas top test points yield the closest agreement with actual compressive strength. The findings confirm that rebound hammer accuracy is position-dependent and should be explicitly considered in concrete strength evaluation.

Abstract

Rotation measurement is a key parameter in evaluating the mechanical behavior of steel connections under moment loading. Direct measurement of rotation using conventional sensors such as Linear Variable Differential Transformers (LVDTs) is challenging, as LVDTs are primarily designed to measure translational displacement rather than angular deformation. This study presents the development and calibration of an indirect rotation measurement device based on LVDT displacement conversion using a mechanical wire–roller system. The proposed device converts rotational motion of a horizontal steel member into linear displacement through a steel wire wound around a roller, which is subsequently measured by an LVDT. The calibration was performed within a rotation range of 0°–30° using a 14 mm roller diameter under laboratory-controlled conditions. Calibration was conducted using two approaches: manual rotation measurement with a protractor and controlled loading using a Universal Testing Machine (UTM) equipped with an anglemeter. The results show that calibration performed using UTM loading provides closer agreement with theoretical arc-length calculations, particularly for small rotation angles. The average deviation of the UTM-based calibration relative to theoretical arc-length calculation was ±0.94%, with a maximum deviation of 5.8% at small rotations. The regression model yielded R² = 0.99, indicating excellent linearity. A linear correlation between LVDT displacement and rotation angle was established and adopted as the calibration equation. The proposed measurement system demonstrates adequate accuracy and reliability for experimental investigation of rotational behavior in steel connections.
