Creep And Shrinkage

In order to analysis of concrete based on ABAQUS, A creep and shrinkage of concrete analysis program TDPA was developed. Firstly, the theory of creep and shrinkage effect of concrete was introduced. with the help of a Dirichlet series properties, creep stepwise recursive method was introduced to avoid stress history of large capacity storage; Secondly, using three user subroutine interface USDFLD, GETVRM, UEXPAN provided by ABAQUS, analysis program TDPA was developed by Fortran program language; Finally, typical long-term load tests of pre-stressed concrete and steel concrete composite members long term tests were selected to prove the reliability of TDPA. Research results show that: the TDAP has high applicability and reliability. It is suitable for a variety of creep and shrinkage prediction model, and provides an effective method for creep and shrinkage of concrete analysis on ABAQUS platform.

RESUMO: Slim Floor é um sistema de pisos mistos aço-concreto de pequena elevação no qual a laje de concreto encontra-se embutida na altura da viga de aço, estando apoiada na mesa inferior do perfil. Este trabalho teve como objetivo estudar essa tipologia de estrutura, verificando a sua eficiência frente à conformação mista convencional de lajes e vigas, comumente conhecida como Steel Deck. Este artigo apresenta a metodologia de dimensionamento de um pavimento Slim Floor bem como os resultados de cálculo para uma estrutura Steel Deck, obtidos por meio do software VigaMix. Foram realizadas análises que envolveram parâmetros como o peso da viga, altura do piso, consumo de concreto e deformação. Dessa maneira, o sistema Slim Floor apresentou vantagens quanto aos aspectos construtivos, econômicos, estéticos e, principalmente em relação à altura total do pavimento. A maior contribuição deste estudo foi oferecer uma orientação para o dimensionamento de Slim Floor, visto que os critérios para a concepção deste tipo de estrutura ainda não se encontram totalmente consolidados nas normas atuais. ABSTRACT: Slim floor system is a mixed steel-concrete floors small elevation in which the concrete slab is built on the height of the steel beam, being supported on the lower flange of the profile. This work aimed to study this type of structure, checking their front efficiency to conventional mixed forming slabs and beams, commonly known as Steel Deck. This paper presents the design methodology of a floor Slim Floor as well as the calculation results for Steel Deck structure obtained through VigaMix software. Analyses were performed involving parameters such as the weight of the beam, floor height, concrete consumption and deformation. In this way, Slim Floor system had advantages as the constructive, economic, aesthetic, and especially in relation to the total height of the floor. The major contribution of this study was to provide guidance for the design of Slim Floor, as the criteria for the design of this type of structure has not yet been fully consolidated in the current standards.
