COST-BENEFIT ANALYSIS BETWEEN SQUARE PILE, CIRCULAR PILE AND STAR PILE

 In the field of civil construction, over time, we can observe significant 
transformations in the technologies used in the sector, such as foundations. 
Following these changes, a new model of reinforced concrete pile with cross
sections in the shape of a star appeared on the market. Therefore, this work have 
as objective to analyze and compare the cost-benefit in function of strength and 
market value between star piles, square piles and circular piles. To carry out this 
research, other literatures that were based on the Decourt-Quaresma method were 
studied. After the calculations, it was concluded that the star pile does not present 
a positive differential in the market, being inferior in the cost-benefit aspect to the 
other piles.
