But it is not good with high prestress level. This paper consider permissible tensional prestress value from three aspects to avoid tensile crack on concrete、interface bonding between concrete and CFRP and disadvantage failure mode of CFRP broke before steel yield.
但是,CFRP片材的张拉预应力值并不是越大越好,本文从三个方面出发考虑了预应力CFRP增强RC梁的容许张拉预应力值,避免了张拉预应力值过高产生的混凝土拉裂缝产生、混凝土与CFRP之间界面剥离和CFRP先于钢筋破坏这种不利破坏模式的发生。

The R/C frame structures were modeled with bar system and the column was modeled with multi-springs. The concrete and steel bars in column were considered as springs in order to reflect the coupling influence between the axial force and the moment-rotation relationship, the hysteresis of springs is based on the material properties and the rotation of column section is followed the plane assumption. The moment-rotation of beam section was modeled with trilinear hysteresis model.
混凝土框架分析模型采用杆系模型,其中柱采用多弹簧模型,柱端的混凝土和钢筋作为弹簧考虑以便反映柱轴力与弯矩-曲率的耦合关系,弹簧的滞回关系根据材料特性确定,柱截面的转动符合平截面假定,梁截面弯矩-转角关系采用三折线滞回关系模型。

A new anchorage system for girder to obtain pretension stress at section top-edge in middle of span is shown. Based on the research of bi-prestressing beams inside test-room and the test of the prestress bar character, method for calculating the full size gird and choosing section are proposed. A new-style corrugated pipe which is shown in the paper is used, to solve the transformation of compressed thread bar and the contradiction between loss of friction resistance and pumping in pipe.
