| 6. | The numerical modeling results show that the smaller the elastic modulus of adhesive in fillet , the higher the peak stress in adhesive layer at the adjacent point to the fillet when hi - adhesives used to form the fillet and bondline respectively and is higher than that of the joint made of single adhesive 结果表明,当胶瘤采用不同于胶层的胶粘剂时,随着胶瘤弹性模量的减小,在胶层与胶瘤的连接处胶层中应力峰值显著提高,且均高于由单一胶所形成接头的应力峰值。 |
| 7. | 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 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 |
| 8. | The repair effect was compared with various type of repair parameters such as patch thickness young ' s modulus and thickness young ' s modulus of adhesive layer . in the chapter iv , a thermalstatic mechanical loading analysis of the repair problem was made . for the single side repair , the patch material having the maximum mismatch in the coefficient of thermal expansion with that of the crack aluminum plate provides the better damage tolerance capability for single - side crack in the panel 模拟计算表明:粘胶模量增大, j积分值降低,修补效果与粘胶模量有关;随着粘胶厚度的增大,修补模型的j积分值略有增大后再逐步减小,应合理选择粘胶的厚度,尽量避免选择j积分较大值时的粘胶厚度;随着补片厚度的增加,修补模型的j积分值逐渐增大,到达一定量后又开始减小,因此补片的厚度需要合理选择。 |
