Dimensionamento estrutural de um edifício residencial em concreto armado utilizando o software Eberick e calculando manualmente

Abstract

This work presents a technical and cost comparison for the results of a structural calculation obtained by the Eberick software and in manual form. The technical analyses took into account the final computation efforts at hand. As for the question of costs, it considers the materials necessary for the execution of the elements. The sizing performed in the program was for the entire structure in question. In the manual calculation, a certain selection of slabs, beams and columns was considered. The object of study is a fully residential building of 6 floors. All the initial calculation parameters were the same for both methodologies. When analyzing the final results, technical differences were found at certain points of the structure which consequently led to necessary reinforcement distinctions. The dimensioning performed in the program resulted in higher stresses and reinforcements. With this, it was concluded that the manual method provides a final structural design more economical in relation to costs. It is worth mentioning that this conclusion is for the comparison of only one selection of structural members. To obtain complete results of which method brings lower total final costs, it is necessary to compare the whole structure. All analyses show how important it is to know how to dimension a reinforced concrete structure by more than one means, in order to reach a reliable and quality final result.
