Aplicação do método de Sulzberger no cálculo do dimensionamento geotécnico de fundações para postes duplo “T” de concreto armado

Abstract

The present study analyzes the applicability of the Sulzberger Method in the geotechnical design of foundations for reinforced concrete poles used in distribution networks and transmission lines. Two embedment conditions are evaluated: simple embedment filled with compacted soil-cement and embedment using a drilled shaft with a concrete base, considering both sandy and clayey soils. This method consists of analyzing the structural element primarily under lateral loads and is developed to present in detail the calculation procedures proposed by the model’s author. To demonstrate the practical and effective applicability of the method, design examples were carried out considering different types of poles, with varying load conditions and lengths. The results indicate that the studied methodology represents a viable alternative for design in situations where lateral loading—predominantly horizontal forces—is governing, as in the case of poles, contributing to increased structural safety and serving as a basis for further studies and related research.
