Abstract

Most fishermen used inappropriate methods to sustain their livelihoods, severely destroying fishery resources. Furthermore, a lack of environmental protection and pollution prevention lead the best coastal and estuarial nurseries to become unhabitable. Several studies have pointed out that fish stocks in coastal waters could be no longer sufficient for the increasing fishing activity and consumption requests. Based on the 1950–2006 global statistics conducted by Food and  Agriculture Organization of the United Nations (FAO) (2012).Artificial reefs are most often constructed to increase the efficiency of fishery resource harvest (Seaman and Sprague, 1991). In engineering practice, the stability of artificial reefs is an important issue in preventing the failure of reef units due to wave and current actions. Some of the artificial reefs have also been designed to serve as low-crested coastal protection structures (e.g. Dalrymple et al., 1991a; Ranasinghe et al., 2006). One particular advantage of these artificial reefs over the conventional submerged breakwaters is the fact that they are multi-purpose units and can be achieved with more cost-effective materials and environmentally friendly construction processes (Harris, 1995; Buccino et al., 2013). Artificial reef model keep looking for modification to get compatibility and efiiciency as submerged breakwater because  the feasibility of artificial reefs for coastal protection is typically evaluated based on the percentage of surface wave height reductionWave transformation analysis in artificial reef do with consideration from some non dimensional variables. Wave transmission process defined with ratio betwwen transmission wave height and incoming wave heightThis research compares 5 types of Artificial reef in numeric model. There are hexareef, bottle reef, star reef, seadome and cube reef. They are tested with Indonesian wave steepness which has value between 0,0013 and 0,012.

Abstract

Generally the concrete behavior can be observed by the experimental analysis. However, since the computer technology development has been increased rapidly, the computer simulations are also able to represent the detail behavior of concrete. This paper presents the modeling response of concrete material subjected to biaxial loading using finite element method software based. The plain concrete plates with dimensions 200mm x 200mm x 50mm and 150mm x 150mm x 50mm are analyzed using various combinations of biaxial loading. The results of the biaxial load combinations are covering the three non-linear regions of compression–compression, compression–tension, and tension–tension. The results of finite element analysis are also show good agreement to the experimental results that been taken from the previous study. The comparison results the difference between analytical and experimental study are less than 5%. Therefore, the concrete material model based on this finite element method software can be used to simulate the responses in the real condition

Abstract

This study compares the different linearity of the kinematic hardening model of the Square Hollow Section (SHS) under cyclic bending loading. Four specimens of a simple support beam cyclically tested in previous research are listed as hot-rolled, hot-finished, and two cold-formed. Using the bilinear, multilinear, and Chaboche models, each specimen is modeled in kinematic hardening. The variables or node sets for each linearity model are estimated using tensile test data, and Chaboche variables are obtained using the least-square fitting method. Each linearity model for each specimen is built-in FEA using a shell model. The numerical model applied the same cyclic loading history as the previous test. The numerical analysis comparison concluded that Chaboche and the multilinear kinematic model generate the expected result fitted to test hysteresis of cold-formed one and cold-formed 2 SHS, but the bilinear models are not fitted. Moreover, all kinematic models are not fit for the hot-rolled and hot-finished SHS compared to the test hysteresis. So, for hot-rolled and hot-finished SHS, the combined hardening is suggested; there is a possibility it is because of the lower yield ratio that both sections have. Overall, during a cyclic bending analysis of cold-formed SHS, multilinear or Chaboche models are preferable if the data is limited.

Abstract

ABSTRAK:Artikel ini membahas tentang perbandingan kekuatan aksial rencana profil WF berdasarkan SNI 03-1729-2002 dan SNI 1729:2015. Pada kedua peraturan terkait perencanaan elemen struktur baja tersebut, diketahui terdapat perbedaan persyaratan dan perumusan yang cukup mendasar. Dalam perencanaan kekuatan aksial tariknya diketahui bahwa hanya terdapat perbedaan pada syarat kelangsingan elemen struktur primernya saja dimana pada SNI 03-1729-2002 persyaratannya adalah L/r<240 yang lebih ketat daripada SNI 1729:2015 dengan nilai L/r<300. Pada perhitungan kekuatan rencananya, rumusan kekuatan nominal yang harus digunakan dalam perencanaan diketahui sama, sehingga nilai kekuatannya pada elemen struktur serupa secara perhitungan akan sama. Pada SNI 03-1729-2002 kekuatan nominal rencana yang dikalikan faktor reduksi sama dengan persyaratan DFBK pada SNI 1729:2015. Namun yang perlu diketahui bahwa dalam SNI 1729:2015 terdapat persyaratan DKI (Desain Kekuatan Ijin) yang juga harus dipernuhi.Disisi lain padasegi perencanaan kekuatan tekannya, kedua peraturan diketahui memiliki persyaratan kelangsingan struktur yang sama yaitu L/r<200. Namun terdapat perbedaan parameter acuan pada persyaratan kelangsingan sayap dan badan, terdapat perbedaan persyaratan pada kedua standar tersebut, namun hasil keseluruhan dari profil WF yang dicoba menunjukkan kesimpulan yang sama untuk tiap profilnya. Kekuatan tekan nominal pada SNI 03-1729-2002 pada kategori pendek lebih besar daripada kekuatan tekan nominal pada SNI 1729:2015. Sedangkan pada kategori menengah dan panjang grafiknya menunjukkan hasil yang berbeda, yaitu  Kekuatan tekan nominal pada SNI 03-1729-2002 lebih kecil daripada kekuatan tekan nominal pada SNI 1729:2015. Selain itu pada artikel ini, dapat disimpulkan juga bahwa untuk profil yang sama dan mutu yang sama, kekuatan aksial tekan ijin profil berdasarkan SNI 03-1729-2002 lebih rendah daripada SNI 1729:2015, hal ini disebabkan oleh faktor reduksi yang berbeda, 0.85 pada SNI 03-1729-2002 dan 0,9 pada SNI 1729:2015. Perlu diingat juga bahwa dalam mendesain elemen struktur pada SNI 1729:2015 harus memenuhi persyaratan DFBK sekaligus DKI

Abstract

The warehouse frame is a specialized steel structure requiring more complexcalculations than standard portal frames. This study investigates the impact ofrafter angle and span length on ductility and stability. Results indicate thatincreasing span length enhances ductility but reduces stability due to higher storydrift. For example, M1 (10-meter span) shows a ductility of 4.62 and story drift of13.64 mm, while M3 (20-meter span) achieves 5.07 (+9.62%) with a drift of 46.77mm. A larger rafter angle slightly increases ductility but decreases stability. M1 (10°angle) records 4.62 ductility and 13.64 mm drift, whereas M7 (20° angle) reaches4.71 (+1.79%) with 16.92 mm drift. Higher structure stiffness reduces ductility butboosts stability. M3 (128.29 kN/m stiffness) shows 5.07 ductility and 46.77 mmdrift, while M12 (192.67 kN/m) records 4.96 (-2.17%) with 29.68 mm drift. DespiteM12's minor ductility reduction, M3 demonstrates better elastic-plastic behavior.These findings reveal a clear polarity between ductility and stability

Abstract

Steel-reinforced concrete (SRC) provides numerous advantages, such as enhanced energy dissipation, ductility, stiffness, and strength, particularly in seismic performance. Several studies on the effect of axial loads on columns found that axial loads have an insignificant influence on column capacity, though they influence long-term performance. Beam-column joint elements are among the critical components that determine the seismic behavior of a structure. Inaccurate design of these joints can lead to fatal structural damage, potentially causing structural collapse. This study aimed to perform a numerical analysis of various joint configurations under cyclic and axial loads to identify models with the best seismic performance that consisted of four models using different SRC length parameters. The research used nonlinear finite element methods with the ABAQUS software, which enables detailed simulations of joint behavior, including predictions of failure mechanisms that are difficult to observe in experimental testing. The results of the analysis showed that the CS-02 model demonstrated the best seismic performance. Axial load increased the capacity in all models, improved energy dissipation in the RC model, slightly reduced dissipation in CS models, and caused different rotational behavior across models.

Abstract

This article provides information regarding the comparison of methods and results for calculating  compressive strength in compression member composite elements of concrete filled steel tubes (CFST) based on three standards (SNI) related to the design and specifications of structural steel in buildings. The three standards being compared are SNI 03-1729-2002, SNI 1729-2015 and SNI 1729:2020. Hollow structural sections (HSS) are widely used as structural elements, then increase their strength and reliability, concrete is added as a filler, known as Concrete Filled Steel Tubes (CFST) Sections. In all three standards, there are the same concept and discussion. Meanwhile, different methods, formulas, and coefficients appear in the calculation of compressive axial strength for CFST, so there are different results. The design axial strength values based on SNI 1729-2015 and SNI 1729:2020 are coincide, even though there are different coefficients. Further, the calculation results of the two SNIs are smaller than SNI 03-1729-2002 due to significant change in the suggested reduction factor. Overall, based on this study, the existing CFST member designed using SNI 03-1729-2002 needs to be re-evaluated, especially in their axial force restraining contribution.
