Abstract

The need for high-rise buildings is increasing as land is limited. Buildings made of steel materials are very good at resisting lateral forces. It is very necessary to analyze the mechanical properties of steel to know that the material can effectively resist the load. Modeling of steel plate material with width of 10 mm, thickness of 1 mm and height of 20 mm. Modeling was done using the Abaqus program with four variations of shell radius 0.01, 0.05, 0.1, and 0.2. Von Mises (tensile) stress results were obtained at the horizontal position of the basin at points A (radius point), B (center), and C (edge). For all modeling variations, the highest stress is at point A and then the stress value decreases to point B and then to point C. The most significant difference in value at each point is obtained for a radius variation of 0.2 with the value of each point A = 2.24059 MPa, B = 1.02566, and C = 0.64195. The steel plate variation with a radius of 0.2 has the largest deformation compared to the other variations. It can be concluded that the steel plate with a radius of 0.2 is more likely to be damaged. In the maximum principal stress value, the 0.2 radius variation also has the largest value compared to other variations.

Abstract

Omah Saka Papat is a traditional Javanese architectural structure. It is characterized by four main wooden pillars (saka guru). These pillars reflect the structure's adaptability to environmental conditions. This includes earthquake risks. This study will analyze the structural strength of Omah Saka Papat under seismic and self-weight loads. The saka guru is a critical element of this analysis. STAAD Pro v8i software and the response spectrum method were used to calculate internal forces and evaluate the capacity of teak wood as the primary material. The findings indicate that the combined compressive stress of 123.34 kg/cm² and shear stress of 0.83 kg/cm² are both below the allowable limits of 150.75 kg/cm² and 20.1 kg/cm², respectively. Structural joints using 12.7 mm diameter bolts satisfy the required strength criteria, with a minimum of four bolts per joint. Omah Saka Papat's structural integrity is proven. It's an earthquake-resistant construction that preserves aesthetic and cultural values. Integrating traditional design principles with modern technology provides a sustainable construction model adaptable to natural disasters. These results will undoubtedly contribute to the development of locally inspired, earthquake-resistant construction technologies suitable for seismic-prone regions.

Abstract

Structural analysis is essential in civil engineering to ensure the' safety, stability, and performance of load-bearing elements such as beams. Conventional approaches—such as manual calculations or commercial software—often involve high costs, limited accessibility, or steep learning curves. This study presents a web-based computational tool for analyzing simply supported beams, developed in Python to deliver accurate, real-time results through an interactive interface. The tool utilizes fundamental static equilibrium equations to calculate support reactions, shear forces, and bending moments in the simply supported beam subjected to point and uniformly distributed loads. Python’s numerical and visualization libraries enable the automated generation of shear force and bending moment diagrams, input validation, downloadable CSV outputs, and adjustable parameters. Validation consisted of three stages: comparison with analytical hand calculations, benchmarking against Tekla Structural Designer (Educational License), and a usability survey conducted among 67 participants from academic and professional backgrounds. The tool’s results matched reference calculations, and user feedback highlighted high accuracy, clarity, and educational value. This open-access platform offers an effective solution for educational use. Future development will focus on extending features such as analyzing more complex structures under various loading conditions, performing deflection analysis, and mobile compatibility.

Abstract

Penggunaan material alternatif pada konstruksi rumah tinggal semakin beragam, salah satunya muncul ide di masyarakat menggunakan dak hebel untuk konstruksi plat lantai. Dak hebel dengan perkuatan frame besi siku dijadikan opsi masyarakat yang ingin membangun rumah dengan dana yang lebih hemat dibanding menggunakan material konvensional berbahan beton bertulang. Tujuan dari penelitian ini untuk mengatahui analisa harga satuan pekerjaan pembuatan dak hebel per m2. Metode yang digunakan dengan membuat maket konstruksi dak hebel  ukuran 2x2 meter, menggunakan bata hebel 20 cm x 60 cm x 10 cm , besi siku std 5 x 5 cm finshing cat epoxy anti karat, hingga dilakukan proses instalasi pemasangan seluruh komponen demi memahami proses kerja, waktu, dan biaya seluruh proses produksi  yang timbul selama proses pemasangan. Hasil penelitian ini menunjukan biaya satuan per m2 pada pekerjaan dak hebel ini adalah Rp. 1.012.375 , dengan 64,24% pada komponen biaya material, 25,31% biaya pekerja, 4,94% pada biaya alat dan 5,51%  biaya tidak langsung. Temuan ini menunjukkan bahwa dak hebel dengan perkuatan besi siku dapat menjadi alternatif ekonomis yang layak dengan potensi penghematan biaya hingga 25-30% dibandingkan dengan sistem plat beton konvensional, namun dengan pertimbangan khusus pada aspek kapasitas struktural dan durabilitas jangka panjang.
