Numerical researches complex of multifaceted composite elements under axial compression
Journal Title: Металлические конструкции - Year 2016, Vol 22, Issue 1
Abstract
In the article the relevance of creating multifaceted pipe-concrete structures (MPCS), associated with the possibility of their use in urban construction as structures that meet high modern demands for their aesthetics and low land allocation has been considered. It has been given the features of a computational finite element model of such structures in ANSYS, which consist in the possibility of nonlinear materials simulation, taking into account contact interaction between them, the use of special types of finite elements that can help to correct numerically describe the structures work under load, and also the principles of the restrictions of degrees of freedom for a structural model. The analytical methods for determining the nonlinearity parameters of the used materials, as well as the physical and mechanical properties of a confined concrete have been described. At specific examples numerically it has been identified and analyzed the changing of MPCS load capacity under various conditions of materials adhesion (a friction coefficient varied in the range 0.1…0.6), and also the changing of steel and concrete deposit level to the total load capacity of the composite structure as a whole. It has been analyzed «the unified» analytical method for determination of the MPCS load capacity with indicating the degree of variability of the compressive limit load depending of the number of face variation and the thickness of a metal wall of the multifaceted model.
