Resumo: | The joined structure-foundation analysis of buildings is one of the studied themes of Soil- Structure Interaction (SSI). In this research, a numerical tool was developed using the Matlab program to evaluate the soil-structure interaction in buildings, where the problem has been studied in the last years, but has not became a current practice in civil engineering. The developed program, here named as AIEFE, predict the settlement using the Aoki and Lopes (1975) method, using as input data the reaction loads of building columns, calculated in any subroutine of spatial-portico analysis. The commercial program TQS was chosen as this subroutine in the present research. The found foundation settlements were converted in stiffness values and, then, inputted again in the structural analysis, predicting new settlements, but no more considering the foundations as fixed points . The method is iterative, aiming to reach the settlement (or load) convergence. Two examples of buildings supported by piled foundations were analyzed. The first one presented an almost square plant and the other one was typically rectangular. The SSI effects were analyzed in terms of column loads and also stiffness and foundations settlements during the constructive process of the 15-levels studied cases. During the construction of the first building levels, it was observed a greater load and settlement redistribution, due the lower structural stiffness. Using the foundation stiffness instead of settlement values was considered as an efficient process of convergence. It was also observed that the non-linear foundation behavior had a great influence in the structure load redistribution, even on advanced construction stages when the structure stiffness has a great value. |

Neste trabalho, desenvolveu-se uma rotina de cálculo no ambiente Matlab para avaliar a interação solo-estrutura em edifícios, onde o tema é estudado há algum tempo, mas que ainda não se tornou prática corrente na engenharia civil. O programa desenvolvido, denominado AIEFE, calcula os recalques das fundações utilizando o método de Aoki e Lopes (1975), utilizando como dados de entrada as reações de apoio dos pilares do edifício vindas de uma sub-rotina de cálculo de pórtico espacial, aqui empregando-se o programa TQS. Os recalques encontrados para as fundações são convertidos em rigidezes e então são inseridos na sub-rotina de cálculo estrutural, onde se processa a estrutura novamente, não mais com apoios indeslocáveis. A metodologia é iterativa de forma a buscar a convergência de recalques ou reações de apoio. Dois exemplos de edifícios apoiados sobre blocos de estacas foram analisados. Um possuía uma geometria em planta aproximadamente quadrangular e o outro retangular. Foram avaliados os efeitos da ISE nas reações de apoio, rigidezes e recalques dos pilares durante o processo construtivo dos 15 pavimentos dos exemplos estudados. Observou-se que nos primeiros pavimentos, devido a menor rigidez da estrutura, tem-se maior redistribuição de carga, recalques e rigidezes nos pilares, e que o processo iterativo em termos de rigidez é bastante eficaz. Verificou-se, também, que o comportamento carga-recalque não-linear das fundações influenciou bastante no comportamento de carga, rigidezes e recalques dos pilares, mesmo em estágios avançados da obra, quando a rigidez da estrutura já era bastante grande.Made available in DSpace on 2014-07-29T15:18:26Z (GMT).
