Abstract

Bored pile foundations are deep foundations that are often used in the construction of large construction sites located in dense areas with the consideration of reducing noise and the influence of vibrations that would occur if pile foundations were used. This analysis aims to calculate the lateral bearing capacity of the bored pile foundation based on the results of analytical calculations using the Broms method, the Davisson method, the Chin method, the Mazurkiewich method, and analyzing the displacement of the bored pile foundation based on loading tests in the field. and the results of soil modeling with Allpile and finite element methods with the Mohr-Coulomb soil model, and the Hardening Soil model. Based on the analysis that has been carried out, the ultimate bearing capacity of the bored pile based on SPT data using the Broms method is 18.92 tons, while the results of the interpretation of the loading test using the Davisson method are 18 tons, the Chin method is 18.98 tons, and the Mazurkiewich method is 19 tons. For the large deflection of a single bored pile with a load of 200% with the Allpile program the large deflection that occurs is 4.25 mm and analysis based on FEM PLAXIS 3D using soil modeling with Mohr - Coulomb large deflection of 3.0 mm and soil modeling with Hardening Soil 2.99 mm.

Abstract

Procedures for planning earthquake resistance for building and non-building structures, SNI 1726:2019 have been approved as a revision of procedures for planning earthquake resistance for building and non-building structures, SNI 1726:2012. With the implementation of SNI 1726:2019, existing buildings should be re-evaluated for their safety against this new regulation. This research examines changes in the performance of shophouse structures in the cities of Sidikalang, Tarutung, Padangsidimpuan, Sei Rampah, Tebing Tinggi, Limapuluh, and Lubuk Pakam. The results show that as a result of the change from SNI 1726:2012 to SNI 1726:2019 there was an increase in the value of the base shear force in the cities of Sidikalang, Sei Rampah, Tebing Tinggi, Limapuluh, and Lubuk Pakam with values respectively 32%, 8%, 11%, 7 %, and 10%. However, in the cities of Tarutung and Padangsidimpuan there was a decrease in the basic shear force value of 3% and 30%. The increase in base shear force is directly proportional to the increase in drift and interstory drift. The interstory drift that occurs is still below the permitted interstory drift.

Abstract

Program pengabdian kepada masyarakat yang bekerja sama dengan Sekolah SMK Negeri 8 Medan bertujuan untuk memberikan eduksi tentang pentingnya konservasi air dan penanganan genangan air dengan pembuatan biopori di area sekolah. Biopori adalah lubang berbentuk silinder yang dibuat secara vertikal menuju ke dalam tanah dengan diameter berkisar 10-30 cm dan kedalaman 80-100 cm. Biopori, sebagai salah satu usaha konservasi air, memiliki beragam manfaat sehingga mampu meningkatkan kualitas lingkungan. Salah satu parameter untuk menentukan keberhasilan konservasi air adalah berkurangnya genangan air di permukaan tanah karena dapat masuk dengan mudah ke dalam tanah. Pengabdian kepada masyarakat ini dilaksanakan dengan memberikan pengenalan mengenai konservasi air kepada siswa dan guru dan dilanjutkan dengan praktek pembuatan biopori di halaman sekolah oleh siswa. Diharapkan siswa dapat melanjutkan membuat biopori tersebut sesuai jumlah yang dibutuhkan dan di lokasi yang tepat di area sekolah, sehingga permasalahan genangan air dapat teratasi.

Abstract

The availability of adequate green open space (RTH) is one of the efforts to maintain optimal environmental quality. The need for green open space is affected by population and area. Based on the Law No. 26 Year 2007 on Spatial Planning, it is explicitly determined that the proportion of public green open space is 20%. Sub-district Medan Baru is a sub-district located in the city center, part of which is a commercial and service area. Sub-district Medan Baru is also one of the sub-districts planned to be the city service center, which has the function of trade / business activity center, service activity center and provincial and city government activities, so the population density in the area is dense and affects the need for green space. The data used in this research are land use map, administrative map of Medan Baru sub-district and green open space coordinate data of Medan Baru sub-district. From the results of the study, it was obtained that the area of public green space in Medan Baru Sub-district is 18.78 hectares and it can be interpreted that the availability of public green space in Medan Baru Sub-district is 3.48% of the total area.

Abstract

Penelitian Pada analisis pondasi, besarnya daya dukung dan penurunan yang terjadi merupakan dua kriteria yang sangat penting. Pondasi wajib memiliki daya dukung yang mampu memikul beban diatasnya, sehingga sistem tranfer beban ke tanah dapat berjalan dengan tetap mengontrol terhadap penurunan ijin untuk menjaga kestabilan konstruksi di atasnya. Analisis ini bermanfaat untuk menghitung besarnya daya dukung dan penurunan yang terjadi pada pondasi spun pile proyek Gedung Rawat Inap Tower-1 RS Haji Medan, secara empiris dengan metode elemen hingga menggunakan aplikasi PLAXIS 3D dengan jenis tanah Mohr-Coulomb dan Hardening Soil Dari analisis yang telah dilakukan, daya dukung ultimate spun pile berdasarkan data SPT dengan menggunakan persamaan O’Neil dan Reese adalah 165,42 ton sedangkan menggunakan hasil interpretasi loading test dengan metode Davisson memberikan nilai 330 ton, metode Mazurkiewich 430 ton dan metode Chin 380 ton. Untuk besar penurunan spun pile tunggal, secara analitis dengan hasil loading test Aksial di lapangan menghasilkan besar penurunan 8,45 mm, analisis berdasarkan FEM PLAXIS 3D Mohr-Coulomb besar penurunan 10,99 mm dan Hardening Soil besar penurunan 9,26 mm. Kesimpulan dari analisis bahwa nilai keamanan yang digunakan saat desain dan analisis penurunan yang paling mendekati hasil di lapangan adalah analisis dengan PLAXIS 3D dengan jenis permodelan Hardening Soil.

Abstract

This study analyzes the axial bearing capacity and settlement of a single bored pile foundation with a diameter of 80 cm used in the construction project of the BRI Tower, utilizing static load testing and the Finite Element Method (PLAXIS 3D program). Field data from the Standard Penetration Test (SPT) and cyclic loading test were compared with numerical simulations using the Mohr-Coulomb and Hardening Soil models. The ultimate axial compressive bearing capacity (Qu) of a single bored pile determined analytically using SPT data and the O’Neil and Reese equation is 454.5 tons. The ultimate axial bearing capacity (Qu) of a single bored pile based on loading test data interpreted using the Davisson method is 492.0 tons, the Mazurkiewich method is 464.0 tons, and the Chin method is 416.6 tons. Based on the Finite Element Method (PLAXIS 3D) using the Hardening Soil model, the ultimate axial bearing capacity interpreted using the Davisson method is 497.0 tons, the Mazurkiewich method is 482.0 tons, and the Chin method is 588.2 tons. Meanwhile, the ultimate axial bearing capacity based on the Finite Element Method (PLAXIS 3D) using the Mohr-Coulomb model is 445.0 tons by the Davisson method, 450.0 tons by the Mazurkiewich method, and 714.2 tons by the Chin method. Based on analytical calculations, load tests, and the Finite Element Method, the elastic settlement of a single bored pile was 18.85 mm analytically, 6.13 mm from the loading test, 8.15 mm from the PLAXIS 3D Mohr-Coulomb model, and 6.11 mm from the PLAXIS 3D Hardening Soil model. Overall, the settlements remain within the acceptable tolerance limit (25 mm). Recommendations include the potential for further development of this research by using other analysis software such as MIDAS. Furthermore, future updates to the axial bearing capacity testing standards are suggested, where analysis of foundation bearing capacity may be performed solely using the Finite Element Method (PLAXIS 3D) or other software.

Abstract

The lateral bearing capacity of piles is a crucial factor in foundation design, particularly under lateral loads. This study analyzes the lateral bearing capacity of hydraulic jacked-in piles using the Broms method and interprets loading test results with the Chin and Mazurkiewicz methods. Additionally, numerical analysis of lateral deflection was conducted using the p-y method in LPile and the Finite Element Method (FEM) in PLAXIS 3D to assess compatibility with field test results. The results indicate that the lateral bearing capacity is 16,20 tons using the Broms method, 18,76 tons with the Chin method, and 16,50 tons with the Mazurkiewicz method. The lateral deflection at 200% load was 11,82 mm from field tests, 14,69 mm from LPile, 12,25 mm from PLAXIS 3D (Mohr-Coulomb), and 11,91 mm from PLAXIS 3D (HS Small). The HS Small model yielded the most accurate prediction, closely matching field test results. This research highlights the importance of numerical modeling in predicting lateral pile behavior and provides valuable insights for foundation design under lateral loads.
