Abstract

Media transmission (Telcom) tower could be a media transmission building structure that employments a combination of steel outlines as its development fabric. Media transmission towers work as a back for a few media transmission types of gear for transmitting signals that back the cellular communication frameworks that we continuously utilize so remote. Communication. In tower planning, the prevailing powerful stack is wind stack since wind may be a sidelong stack that encompasses a tall affectability to steel development buildings (incorporates a mass that tends to be light). The tallness of the tower that's made depends on the area of the tower itself. The most issue in this inquire about is how to dissect the tower upper–structure in arrange to determine whether it is solid or not to preserve Wind load analysis on BTS (Base Transceiver Station) towers is one of the important aspects in the design of telecommunication tower structures. Wind load can affect the stability and strength of the tower, mainly due to the height of the tower and the nature of the load which tends to change according to the wind speed and the shape of the tower. Study in this research will is about ”Upper–Structure Analysis of Bts Tower on High Wind Speed Area” as a solution to the problems that often occur in the field and until now still often appear structural infeasibility in the selection of construction systems for BTS Tower planning.

Abstract

Analisis struktur bangunan pabrik sigaret konstruksi baja menggunakan ETABS bertujuan mengevaluasi kekuatan dan kinerja struktur dalam menahan beban statis (material, peralatan) dan dinamis (getaran mesin, angin, gempa). Hasil analisis menunjukkan struktur memenuhi kriteria keamanan berdasarkan SNI 1726 : 2019, dengan simpangan antar lantai pada lantai 2 akibat gempa arah X dan Y tidak terdeteksi, mengindikasikan stabilitas struktur yang baik dan kemampuan mempertahankan posisi tegak selama gempa. Analisis kombinasi beban gravitasi dan lateral menggunakan ETABS juga membuktikan struktur mampu menahan beban geser maksimum tanpa risiko kegagalan atau kerusakan signifikan. Validasi melalui metode analisis manual dan perangkat lunak memperkuat konsistensi hasil, terutama dalam respons dinamik (spektrum respons dan time history). Temuan kunci menyatakan struktur baja pabrik telah memenuhi syarat ketahanan gempa dan distribusi beban optimal, dengan tahanan struktur yang melebihi beban kerja. Namun, rekomendasi utama penelitian mencakup: (1) pemantauan berkala terhadap sambungan baja dan elemen penahan getaran mesin untuk memastikan durabilitas jangka panjang; (2) analisis lanjutan menggunakan input gempa riil (time history) guna mengantisipasi variasi beban dinamis ekstrem; (3) optimalisasi desain kolom dan balok pada area dengan konsentrasi beban mesin tinggi untuk mengurangi potensi fatigue. Hasil analisis tidak ditemukan Simpangan Antar Lantai pada gempa arah X dam Y Untuk lantai 2. Penelitian menekankan pentingnya kesesuaian antara kapasitas tahan struktur dan beban eksternal, serta penerapan protokol pemeliharaan preventif sesuai standar nasional. Hasil ini menjadi dasar rekomendasi desain struktur baja sejenis yang efisien, aman, dan berkelanjutan di wilayah rawan gempa.

Abstract

Drainage analysis and planning in an effort to prevent flooding at the Mahroja Commercial Center Tasikmalaya was carried out with a hydrological analysis method in the Cimulu River Sub-watershed, Tasikmalaya City, to estimate the planned rainfall and flood discharge for the 25-year plan. Daily rainfall data during 2007–2019 from the nearest stations (Cimulu, Cikunten II, Kawalu) were analyzed by arithmetic method to obtain the average rainfall of the area. Statistical frequency analysis was carried out by checking the match of the probability distributions of Gumbel, Log – Normal, and Log – Pearson Type III. Based on the chi-square test, it was obtained that the Type III Log-Pearson distribution provided the best match. The 25-year planned rainfall ranges from 124.48 mm (Normal), 137.74 mm (Gumbel) to 159.33 mm (Log – Pearson). The intensity of peak rainfall was calculated from the IDF (Intensity–Duration–Frequency) curve and used in the Rational method (Q = 0.278· C·I·A) to calculate the plan discharge. The hydraulic model of the regional drainage channel (Mahroja Commercial Center) was made with EPA SWMM 5.1 software (25-year planned rainfall input, DTA 18.8 ha). The results of the SWMM simulation show the value of the planned flood discharge at vital locations (namely: C8 shopping complex of 0.877 m³/s, about 37.8% of the capacity of 2.3196 m³/s; peak in channel C10 of 2.496 m³/s, 59.3% of the capacity of 4.2057 m³/s). This condition indicates that the commercial drainage system is safe against 25 years of flooding. The results of this study are important as a technical basis for flood mitigation in the Cimulu Sub-watershed – namely: planning vulnerable areas and increasing drainage capacity – so that the burden of large rainfall can be reliably overcome.
