Steel Fiber Concrete Analysis And Optimization Design Of Beam String Structures

Because the steel fiber concrete compared to the common reinforced concrete has a more superior performance, already more and more was widespread is applied to each kind of project domain.The steel fiber concrete is one kind of new compound material, there are many factors affect its mechanics performance, in the process of promoting the steel fiber concrete technology development and the practical applatication, it is extremely vital significance to research its basic mechanics performance and the basic theory further.This article uses the thin view mechanics finite element method, based on cuts the slipping lag theory, in the elastic scope, separately to unidirectionally pulled the steel fiber concrete volume element model is carried on with the unidirectional bearing situation under the value computation, obtained the stress field distribution and the contact surface shearing stress distribution under the different operating mode.and did the contrast and the discussion with the theory value;calculating the finite element model under the joint action with pull stress and press stress, obtained the fiber and the substrate stress field distribution and the contact surface shearing stress distribution under the stick and partially escapes stick.And discussed the influence which caused by thin grid, the insert length of steel fiber, volume ratio,substrate intensity,fiber rigidity and so on.Using ansys software's formidable function around process, calculating the steel fiber concrete volume element model which has the separate crack.By the biggest pull strain criterion to judge whether the crack is open, anlysing various components' change of stress field and the contact surface shearing stress around the crack dehiscence.This article is for the purpose of looking for one computational method...
