Good Agreement

A new reinforcement technology with prestressed helical rib steel wire bonded in sawed grooves in the concrete cover is presented, based on the deficiency of the presented reinforcement methods. Four test beams NSM prestressed steel spiral ribs are tested in this paper. The stiffness expression of the reinforced concrete beams in different stages is derived and the stiffness formulas of the reinforced concrete beams are gained, based on the general deformation principles of reinforced concrete beams and the characteristics of the reinforced concrete beam NSM prestressed steel spiral ribs. The results of the calculation and the experimental results show good agreement. It shows that the reinforced concrete beam NSM prestressed steel spiral ribs can effectively delay the development of cracks, reduce the component deformation and increase its stiffness. The results provide an experimental basis for the reinforcement method in practical engineering applications.

First Case

Based on earlier theoretical works on RC beams ,the mechanical properties of steel reinforced concrete beams strengthened with FRP(fiber reinforce polymer) are further investigated theoretically including theirs failure mechanism and loadability. According to the design method of reinforced concrete beam strengthened with FRP, steel reinforced concrete beam strengthened with FRP mainly can have three kinds of destruction patterns: the first case is the tensile steel yield, the tensile shaped steel yield, the FRP are put off, the compressive zone’s concrete has not crushed; the second case is the tensile steel yield, the tensile shaped steel yield, the FRP are put off; the compressive zone’s concrete has crushed; the last case is the tensile steel yield, the tensile shaped steel yield, the FRP are not put off, the compressive zone’s concrete has crushed. The second case is discussed in this paper.Based on the different position of middle axle and steel, steel concrete beams strengthened with FRP include: middle axle through the steel web, and not through the steel and just in steel compression flange . Aim at these three kind of situations, the stress are analysed. According to the stress patterns of steel reinforced concrete beams strengthened with FRP and different position between neutral axis and steel, the discriminant formula of the boundary destroys and the formula of cross-section flexural capacity calculation are put forward by using limit equilibrium theory.The formula is expressed clearly, simple and easy to use.The depth of compressive region is given in view of different failure types.
