| Steel concrete composite structure is a new kind of structure which is developing based on steel structure and reinforced concrete structure. In order to give full play to steel and concrete, shear connector is needed between the two structures. With the progress and application of combined structure, the research of shear connector is given more attention and developed widely.In this thesis, firstly, the developing history of shear connector, present research situation and brief classification of shear connector were introduced. Secondly, present research method of PBL shear connector and analysis way of ultimate bearing capacity were introduced. Lastly, technology and experiment on model are made to analyze the influence of several parameters on PBL shear connector. Research details are as follows:1. The developing history of shear connector and present research situation and expatiate on the classification of shear connector from form and rigidity were introduced. Merits and demerits of those shear connection and their applications were also discussed.2. The progress of PBL shear connector, research method and analysis of its ultimate bearing capacity including analyzing the main parameters through the classic formulas were introduced.3. The design of experiment model were introduced. The load, making and testing of experiment are well stated.4. Calculate and analyze the specimen through damage model and state the characteristics of ABAQUS and damage model.5. Analyze the experiment results of PBL shear key. At last, a summary is given through the main work and research results in this paper and a better experiment method of shear connection is put forward. |
