PBL键机理与试验研究
|
摘要
近二十年来,随着钢-混凝土组合结构在我国的快速发展,新型的PBL剪力键越来越受到关注。组合结构性能的优劣,很大程度上取决于钢与混凝土界面处剪应力能否有效传递,对剪力连接件也提出了更高的要求,相反,新型的PBL剪力键的研究与传统的连接件相比较少,对于应用在在锚固区中的PBL键的研究更是几乎没有。本文依托建设中的青岛海湾大桥红岛航道桥的索塔锚固区,对PBL新型剪力键进行了试验和理论研究。论文主要研究内容如下：
选取实际工程索塔锚固区实际模型PBL键发挥作用的主要部分,设计制作了3个缩尺试验模型以进行对比分析,采用拉荷载而非传统的压荷载,更加符合实际情况。通过不同的工况,得到了大量关于PBL剪力键应力、钢板位移及应力、钢板加劲板应力、混凝土应力的数据,进一步研究了应力和变形的分布规律。
采用通用有限元软件ANSYS对拉出试件进行有限元模拟,得到各工况下的计算结果。通过与模型试验的实测值进行对比分析发现,数据规律基本一致,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。同时也为有限元分析与模型试验相结合的研究方式提供参考价值。
选取一些参数,对试件进行量化分析,并通过曲线拟合研究荷载与相对滑移量的关系,从而更好的了解PBL键受力性能的主要影响因素及PBL剪力键的作用机理,为以后相关的研究提供参考。
With the rapid development of steel-concrete composite structure in China, the new PBL shear connectors attract more and more attention in the past two decades. The merits of the performance of composite structure depends largely on the effective delivery of shear between steel and concrete, and the shear connectors are proposed a higher demand. On the contrary, the study of new PBL shear connectors are less than the traditional shear connection, and there is nearly no research of PBL shear connectors applyed in the anchorage zone. This article relying on the the cable-pylon anchorage zone of the Hongdao Channel Bridge of Qingdao Bay Bridge which is under construction, makes trial and theoretical analysis to the PBL shear connectors. Main contents of the dissertation are as follows:
We selected the main part of the cable-pylon anchorage zone in which the PBL shear connectors play role, produced three reduced-scale test model for comparative analysis, applyed tension force rather than the traditional pressure, which is more practical. Through different conditions, we gain large amounts of data of the stress of steel structure, concrete and PBL shear connector, and the displacement of the steel plate, and carry on further study of the distribution of stress and deformation.
Using finite element software ANSYS, we gain results under different conditions. Compairing the experimental data to the theoretical results, we find that the pattern is similar. So between the entire loading process, the work was in good condition, there was no apparent failure phenomena, and the capacity had surplus safty reserves. Meanwhile, a new method includes the finite element method and experiments is provided to be referenced.
Select some parameters to carry on quantitative analysis, and study the relationship of load and relative slip by curve-fitting. Thus we can find out the key issues affecting capacity and comprehend the mechanism and failure modes of PBL shear connectors to give a reference.
