Introduction Civil engineering structures, particularly high-rise buildings are especially susceptible to random vibrations; whether it is from high ground accelerations, strong wind forces or abnormal loads such as explosions.
The first method uses the effective independence method (EfI), which based on the maximization of the Fisher information matrix (FIM) determinant, now is one of the most influential and commonly used method in civil engineering.

Finite Element Analysis of Shearing Bond Behavior of CFRP-Concrete Interface Hong Hai 1, a, Wei Wang 1,b 1 Department of Civil Engineering, Shenyang Jianzhu University, 110168, China acehhai@sjzu.edu.cn , bstarwei2002@163.com Keywords: CFRP, High-strength concrete , Interface, Explicit finite element ,Shear failure Abstract.
The debonding behavior at the interface between carbon fiber-reinforced plastic (CFRP) sheet and concrete is a key problem for the application of FRP plate, which has been widely applied in the civil engineering for rehabilitation and retrofitting of conventional structures.
Introduction Carbon Fiber Reinforced Polymer (CFRP) is widely used in the field of civil infrastructure as strengthening and rehabilitation materials because of the characteristics of high strength, high stiffness, light-weight, excellent corrosion resistance, ease and speed of installation, etc.
The high-strength concrete has been widely used and made significant technical and economic benefits because of its high strength, good durability, small deformation, etc., it can meet the requirement of large span, over loading and high-rise development of modern engineering structures .

Basic principles of using value engineering to bidding Value engineering by the functional analysis, to save resources and reduce costs , has a wide application.Values in value engineering has a special meaning, can be expressed in the following formula: v= f/c (1) Where: v is the value of the product, and f is the functionality of the product, c is the cost that to achieve this functionality.By the above formula, a level of product value, depending on its features and to obtain the cost of the ratio of the two.
Herefore, indicators such as quality, duration, can be regarded as owners requested feature, seen as quoting function of costs, in accordance with the principle of value engineering, with a minimum investment to implement functionality.
In view of this, a value engineering evaluation model based on integrated weight is presented.
