Variation analysis effects of square and rectangular columns section with different longitudinal reinforcement rates in the main reinforcement two pile caps analysis

Abstract

The transition between the columns of building and foundation had been used the pile-cap structural elements. The most appropriate method for the pile caps design is the Strut and Tie model. In most cases in the structural project is not considered the influence of certain parameters: the columns cross section and the amount of longitudinal reinforcement columns. This paper studies the effect of the variability of the geometric section of square and rectangular columns, with different longitudinal reinforcement rates, in the main reinforcement traction two pile caps. The basis for study was development experimental program in the Structures Laboratory of EESC-USP . The traction reinforcement bars strains are reduced the pile-caps central section to pile-caps sections that approximate cutting axis shows the experimental results. In models with columns of elongated rectangular section and with great reinforcement rates this reduction is smaller.

Optimum Design of Sunken Reinforced Enclosures under Buckling Condition

“…Mohammad and Seyan optimized the design of reinforced concrete with rectangular column shapes subjected to axial compression as well as biaxial bending moments [16]. The effects of different column sections (square and rectangle) with different longitudinal reinforcement rates have also been studied [17].…”

Análise numérica de blocos sobre duas estacas com variações das seções dos pilares, das rigidezes dos blocos e taxas de armaduras dos pilares

“…Nas Figura 8 e Figura 9 mostram-se como ocorreu a evolução da fissuração nos modelos ensaiados. Os modelos, em geral, apresentaram a primeira fissura com valores entre 20% a 27% da força última, sendo que os pilares de seções quadradas apresentaram a primeira fissura mais tardiamente (MUNHOZ; GIONGO, 2017).…”
