Uncertainty analysis of calculation model for strengthened<br /> with bonded steel plates<br />
Journal Title: Science Paper Online - Year 2009, Vol 4, Issue 7
Abstract
By taking the members strengthened by Steel Plates as the research object, the uncertainty factors of the calculation model were analyzed by using reliability method. Firstly, the influence of uncertainty factors about calculation model for steel plate reinforcement was summarized. On this basis, the tests data from 63 reinforced concrete beam strengthened by bonded steel plates were collected, and investigate range involved many factors, including the damage degree of beam to be reinforced, the consumption of steel plates, initial load, the distance between anchor bolts, the types of adhesives used in pasting and so on. Secondly, according to the probability analysis for sample value of uncertainty statistical parameterKp, Kprepresentative value, 0.76, was obtained under the conditions when the confidence level was 95% and degree of freedom was 4. Finally, the corrected resistance model of normal section in reinforced concrete beam strengthened by steel plates was summarized. The research result has certain reference significance to reliability study of strengthened concrete members.
