摘要:
在弹性理论的基础上,利用钢板锚固剪应力计算公式,对在集中荷载或均布荷载作用下采用粘钢加固的混凝土梁,分析钢板锚固最大剪应力的有关影响因数 .结果表明,最大锚固剪应力不但和混凝土梁的截面高度、跨度等参数有关,还和粘胶层厚度、弹性模量、钢板厚度及钢板长度有关 .采用文中方法可以对钢板端部最大锚固剪应力进行验算,防止混凝土梁出现局部受拉破坏 .研究结果为进一步完善我国粘钢法加固设计提供重要的参考资料 .
Abstract:
Regarding the RC beams subjected to concentrated load or even load and braced by bonding steel,an analysis is made on the relevant factors influencing maximum anchorage shear stress of steel sheet.The analysis is based on elastic theory and makes use of the formula for calculating anchorage shear stress of steel sheet.As indicated by the results,the maximum anchorage shear stress not only realtes to such parameters as height of cross section of RC beam and span but also relates to the thickness of adhesive layer,elastic modulus,thickness of steel sheet,and length of steel sheet.The present method will check maximum an chorage shear stress on the end of shear sheet so as to prevent RC beam from local damage.The present results will offer important reference for our country to further perfect bracing design by bonding steel method.
