Program Test For testing the validity of the program, a engineering case with cross-section of single box with five rooms is chosen[9].
Not only the grillages after division can be automatically drawn and directly displayed in the AutoCAD, but also the feature parameters of section can be auto-output and saved as text file which is easily called by the software for bridge analysis such as Midas/Civil.By comparing with the finite element software ANSYS, the reliability of the program and the accuracy of calculational results are verified.

(2) When there are more damages, each damage index has obvious mutation and the interaction between the damages is very small, which easily operate in practical engineering
(3) The analysis of the measuring points on the effect of identification result shows that, as long as the damage index in this order is sensitive, this method can identify damage location and degree very well with less measuring point References [1] Hongnan Li, Dongsheng Li: Safety assessment, health monitoring and damage diagnosis for structures in civil engineering [J].

Introduction It is a future our country development trend to make use of a low metal alloy steel to carry on engineering construction.
This text mainly elaborated to adopt low metal alloy steel and low-carbon steel make into a low metal alloy steel through the even weld double reinforcing bar, pass to experiment analysis, make sure its mechanics and craft function index sign; Use concrete structure design norm as the theory foundation that is analytical and experiments a data, set up lately just degree and crack model formula, provided for the later engineering construction basis.
(11) Conclusion Application research for coupled steel bars technology, not only apply to foundation, work, consolidation of foundation pit, foundation beam, foundation mat, column, pile foundation, bracing of slope, anchor rod of soil stratum and rock, but also apply to irrigation works, road engineering, bridge engineering, etc[4].
