摘要:
认识到PBL剪力键在土木工程各方面发挥了越来越重要作用,先对其极限承载力理论计算公式做了简单分析和讨论,其次利用MIDAS FEA建立了有限元模型,对其静力荷载下位移应力等进行了分析比较,最后计算了在不同工况下PBL剪力键的关键位置处的应力和位移,计算结果表明:表明模型在整个加载过程中,工作状态良好,没有明显的破坏现象,承载力具有较大的安全储备。

Abstract: In view of PBL shear key playing an increasingly importantly role in all aspects of civil engineering, we firstly analyze and discuss the theoretical formula, then make model with MIDA FEA. Dis-placement stress from static load had been analyzed and compared. At last, PBL shear bond stress at critical locations and displacement in different conditions is calculated. The calculation results show that: The model in the whole loading process, works in a good condition with no obvious damage phenomenon, and the carrying capacity has a large safety margin.
