改进型PBL剪力键受力性能试验研究
|
摘要
本文概要介绍了钢-混凝土组合结构的基本概念和研究状况、钢-混凝土组合结构常用剪力键的类型及特点。在原PBL剪力键基础上提出一种改进型PBL剪力键。并对PBL剪力键、改进型PBL剪力键和鞍形剪力键3大类共9个试件进行了试验研究。通过试验研究和理论分析,论证改进型PBL剪力键的力学性能,建立初步的设计计算方法。本文主要开展了以下几个方面的工作:
①在原PBL剪力键的基础上提出一种改进型PBL剪力键,探讨了其构造原理和传力机制。
②通过试验研究,分析PBL剪力键、改进型PBL剪力键和鞍形剪力键3大类剪力键的受力性能,荷载-滑移曲线规律、抗剪刚度及破坏形态等,并对他们进行比较。
③建立改进型PBL剪力键有限元分析模型,依据试验结果对其中参数进行修正,有限元模型分析结果与试验结果吻合较好。在此基础上,对不同混凝土强度、贯穿箍筋直径、钢板开孔大小和钢板开孔间距下的改进型PBL剪力键进行单因素的拓展参数分析,研究各因素对改进型PBL剪力键受力性能的影响。
④依据试验研究和理论分析,建立了改进型PBL剪力键在剪切荷载作用下屈服承载力和极限承载力的初步计算公式。

PBL shear connectors as well as improved PBL shear connectors, and saddle-shaped shear connectors were studied, a total of 3 categories nine specimens. Through testing research and theoretical analysis, the mechanical properties of improved PBL shear connectors are demonstrated ,and preliminary design and calculation theory are established . In this paper,the main content are as follows:
①on the basis of common PBL shear connectors, an improved PBL shear connector is proposed. This passage is to investigate its construction principles and transfer mechanisms.
②Through testing research, 3 categories shear connectors are analyzed. The content of analysis are their force performance, load - slip curve of the law, shear stiffness and failure mode and so on. Finally, they are compared each other .
③The finite element model of improved PBL shear connector has been built,and according to test results in which parameters were modified,than finite element model agree well with the experimental results. On this basis,the expansion parameters of single-factor with the different strength of concrete, through the stirrup diameter, steel plate hole size and spacing of openings under the improved PBL shear keys are analyzed.And various factors on the improved PBL shear connector force performance are researched.
④Through experimental study and theoretical analysis, the calculation for the yield bearing capacity under shear load and the ultimate bearing capacity of improved PBL shear connector are put forward.
