Analisis Daya Dukung dan Defleksi Lateral Tiang Tekan Hidrolik Diameter 0,6 M dengan Uji Beban Statik Lateral dan Metode Elemen Hingga pada Proyek Gedung Rawat Inap Tower-1 RS Haji Medan

Abstract

The lateral bearing capacity of the pile becomes very important when the structure receives lateral loads, for that high-rise structures, long-span bridges, and seaside structures, which are very common in North Sumatra, certainly require pile foundations that can receive lateral loads. This study aims to analyze the lateral bearing capacity of hydraulic jacked-in piles with empirical analysis using the Broms method and based on the interpretation of the results of lateral static load tests using the Chin method, Davisson method and Mazurkiewicz method. In this study, a numerical analysis of the lateral deflection of the pile was also carried out using the p-y method with the LPile program and using the finite element method with the PLAXIS 3D program to see the level of conformity with the deflection results of the lateral loading test in the field. Based on the analysis that has been done, the lateral bearing capacity of the hydraulic jacked-in pile using the Broms method is 16.20 tons, for the Chin method it is 18.76 tons, the Davisson method is 13.22 mm and the Mazurkiewich method is 16.50 tons. The amount of lateral deflection from the results of the lateral loading test in the field for a load of 200% is 11.82 mm. Meanwhile, the deflection result with LPile program is 14.54 mm and the deflection result with PLAXIS 3D software for Mohr-Coulomb model is 12.18 mm and for HS Small model is 11.86 mm. It turns out that HS Small model is the one that gives the closest result to lateral loading test result in the field.
