摘要/Abstract

摘要： 利用梁底粘贴钢板,提高中小跨径桥梁的承载力,具有许多优点,越来越多地在工程实践中被采用。国内许多单位做了大量的试验,获得了一定的试验资料,但仍缺乏理论性的分析和研究。本文以文献[1]的试验资料为依据,分析了粘贴钢板破坏时的力学特性,阐述了以试验结果为理论依据的基本假定和计算理论。

Abstract: The strengthening mechod by sticking steel bars on the bottoms of bridges has a lot of merits.It is used more and more in engineering.Many experiments have been made and some materials have been got.But we still lack the theoretic analysis and studies.This paper gives the analysis of the mechanical characteristics in the design method.It also presents the basic hypothesis and design theories according to the experimental materials in Ref.l.

Key words: strengthening design by sticking steel bars, similarity of plane hypo-thesis, stress discount
