Fig. 1 The construction plan schematic diagram Selection of raw materials.
For carefully selection of raw materials, the coarse-to-fine aggregate used enjoyed good gradation and less mud, reducing the amount of cement and the heat of hydration.
According to the theory of fiber spacing, there are millions or billions of fibers per unit volume, which can effectively help to prevent the composite material from crack and its expansion before and after stress when composite material forming structure and being damaged by force.

ANSYS finite element mode In this paper, the choices of frame joint units are as follows: 3 D solid model is used to simulate the concrete for this model is specially developed for inhomogeneous materials such as concrete and rock, which has much more compression resistance than tensile resistance. 3 D strut and tie element LINK8 is used to simulate the steel bar, SOLID 45 element is used to simulate the steel skeleton.
