Comprehensive Evaluation on Effects of Strengthened by Bonding Steel Plate or CFRP Based on Analytic Hierarchy Process

Abstract

Pasting steel plate and CFRP are two methods which are usually applied to bridge reinforcement engineering. In order to make a comprehensive evaluation of the effects of the two strengthening methods, two groups of reinforcement testing that simple supported RC beams were preloaded to cracking under the same conditions are conducted, and then reinforced by bonding steel plate or CFRP on the tensile side and increasing section area on the pressure side, to study the strengthening effects of the two methods. Then according to the technical characteristics and contrast test research results, by using the basic ideas of analytic hierarchy process, establishing two levels comprehensive appraisal index system, to evaluate the strengthening effect of the two strengthening methods, the evaluation results show that the performance of pasting steel plate comprehensive is better.

Optimized Design of Polyethylene Fiber-Engineered Cementitious Composite Mix Ratio Based on the Analytic Hierarchy Process

“…References [20][21][22] used various sets of evaluation criteria to analyze the damage to reinforced concrete structures. References [23][24][25][26] determine the priority of bridge maintenance by using AHP. Reference [27]used AHP to reduce the fire risk of cultural relics and buildings and subsequently improve the guideline for public fire safety assessment.…”
