Elastoplasticity Analysis Of Steel-Carbon Fiber Reinforced Concrete Composite Ribbed Shell

The carbon fiber enhanced concrete is one of compound materials which mix the fine performance's carbon fiber in the concrete.With the carbon fiber mixed in,it will strengthen the intensity of the concretes,slows down the development of the crack,and has a function that can consumes energy.Moreover,by using the carbon fiber own physical property,the carbon fiber reinforced concrete will be changed to one kind of new intelligent material.The steel - concrete composite ribbed shell is one kind of new large span space structure,it has outstanding performance of both the steel and the concretes material.As one kind of thin shell,it can be casted as thinly as better in allows. It is proposed that the rib shell can be applied in the carbon fiber reinforced concrete material to use its fine performance,we hope to make the shell as thinly as we can or can enhance the supporting capacity of the entire structure.The paper uses the ANSYS finite element software to analyze the different material form's shell and the overall construction of the composite ribbed shell and contrasts the result at the same time.The papers primary coverage is listed as follows:1.Under the massive domestic and foreign empirical datum's support,it is summarized on the carbon fiber concretes' each mechanical properties and its intelligence properties systematically,meanwhile,the paper analyzes the carbon fiber concretes own mechanical properties parameter and its O - erelationships.2.The analysis is carried out on the dehiscence load,the normal use limiting condition load,the limit supporting capacity of the carbon fiber enhanced concretes and the carbon fiber reinforced bars concretes shell which with the different span different thickness by using the ANSYS finite element software.Moreover,the contrastive analysis on the carbon fiber concretes shell and the reinforced concrete shell is carried out to select the superior material plan applied in the composite ribbed shell.The result showed that the carbon fiber enhanced concretes shell has certain superiority.3.By using the ANSYS,the detailed elastoplasticity analysis is studied in the carbon fiber concretes combination ribbed cylinder shell and the result contrasted with the reinforced concrete composite ribbed cylinder shell performance.The analysis result indicated:The distribution of large span space steel - carbon fiber concretes composite ribbed shell's endogenic force is quite reasonable,and this composte ribbedshell is one kind of quite ideal spatial structure form.Compared to the reinforced concrete, regardless of being the elastic stage or the plastic stage,the carbon fiber concretes composite ribbed shell performes a better distortion,reaction,endogenic force and the stress properties.Finally,the thesis summarizes the research content and looks forward in the steel-carbon fiber concretes combination ribbed shell and the carbon fiber concretes material prospects' development and the possible research direction.
