DIMENSIONAMENTO E VERIFICAÇÃO DE PILARES METÁLICOS TRELIÇADOS E DE ALMA CHEIA EM SUBSTITUIÇÃO A UM PILAR DE CONCRETO ARMADO

Abstract

This paper presents a comparative study of pillars supporting a coverage in metallic structure. Such an approach is necessary because the current state of a pillar of reinforced concrete, a shed of LPmáquinas company, caused by an impact during a maneuver a tractor. The objective of this study is the replacement of the a pillar of reinforced concrete by a metal pillar, being necessary to compare the pillars treliçados and soul filled with the objective to verify which of the proposals is the most recommended in the cost requirements, performance, durability, among others. This aim will be achieved from the literature review and case study, based on technical literatures of renowned authors from the area, manuals and standards used in the country. With the purpose applied, aiming to employ the knowledge acquired in one case study, the geometry and dimensions of the metal cover of the shed will be measured in the company to be able to estimate the loads currently employed on the pillar of reinforced concrete which will be replaced. Being estimated all the efforts that the metal cover applied on the pillar, shall be obtained the forces exerted on the pillar, so can be done the sizing of metallic pillars and the verification of the same, where the results of the sizing of metallic pillars obtained through the calculations are present at work, thus using the qualitative approach, will be examined in the data acquired in the sizing calculations with the aim to demonstrate what model of metallic pillar more correct and economical to be applied and suggested to the structure that is currently installed in the company.
