Economic feasibility analyses of bridge aseismic strengthening
The negative influence of bridge damage on the transportation system under earthquake is discussed in this paper. The relative direct and indirect loss of the damaged system is researched. Based on the constitution of user cost, the unit user cost is assessed through building traffic demand and distribution model. Comparing the retrofit invest and benefit, the method of assessing economic feasibility of bridge aseismic strengthening is suggested.
Recently, Advancements in information technology increasingly compact, lightweight, easy to pursuing the needs of users as (Needs) to meet the complex application of various types of products have been released. In this study, Numerical analysis of stress distribution and to optimize the location of the inserted device use to consisting of PVC material on the card and load displacement. In addition, through the bending test to evaluate the reliability of the specimen was carried out the validation of numerical analysis.
