The Three Dimensions Issue Of Reinforced Concrete Not Line Finite Element Analysis

Reinforced concrete finite element analysis is an important research direct in structure analysis realm. It can comparatively nicety analyses the endure force capability of many complex configuration in engineering, and these configurations system sometimes difficult to using examination methods to make certain. In this science field, the research of three dimensions issue of no linearity is a hot question for discussion nowadays. This discourse will narrate all various content of reinforced concrete finite element analysis in system. Much research of this field only localized in two dimensions issue of no linearity analysis in our country. In order to avoid the content repeat at low level, this discourse's content main research in three dimensions issue of no linearity. It main includes some facts as hereinafter.(1) Brief introduction of element: this discourse introduce twenty nodes concrete element, twenty nodes elastomer element, three nodes equality parameter link element, two nodes link element.(2) Finite element model: the content includes three kind models. It is combination model, separate model and integer model. This discourse emphasis narrates the two behind model.(3) The material's stress-strain relation and ruin rule: the material's stress-strain relation and ruin rule of concrete are both use four parameters, the steel's use two snap model.(4) Simulating of the ruin concrete element: the ruin concrete element include craze, crunch, crack close and so on. They directly affect the precision of the result of reinforced concrete finite element analysis. So this discourse will by way of an independence chapter to narrate.(5) Program design: to work out a utility analysis Program is the absolutely necessarily tache of finite element analysis, and also is this discourse's finally aim. The program uses VC++ language. It is mainstream face object program language today. This discourse develops some element kinds specialize for reinforced concrete finite element analysis.(6) Program validating: this discourse will from many angles tovalidate the program, in order to assure it is feasibility and validity. Linearity analysisresult main compare to theory result. Because no linearity analysis hasn't theory result, commonly nonlinear analysis result compare to ANSYS software analysis result, and the nonlinear value of concrete will compare to experimentation value.
