The Research For The High And Strong Stud Bolt Joint Of Steel Beam And Concrete Wall With Inside Covering Up Profiled Bar

In recent years, the steel frame-shear wall structure system to get the more and more extensive application in our country. But the performance of the joint of steel beam and concrete wall directly influence the integral performance of the steel frame-shear wall structure system, so it attracts the more importance to itself. This paper accomplished the experiment research for the high and strong stud bolt shear-resistance joint of steel beam and concrete wall with inside covering up profiled bar, and on the basis of the experiment data, the joint intensity, rigidity, influence factor and the loaded mechanism of the joint and the restrict capability of the connection plate were analyzed, the main contents concentrate on the following aspects:1. Having the low period repeat loading experiment research for six different joints with different stud bolt specification, different connection plate thickness and different stud bolt arrangement each other, describing the experiment process and experiment phenomenon and getting the relative experiment results such as hysteretic curve and framework curve etc.2. Contrastively analyzing the experiment results of the six joints, researching some factor's influence on the work performance of the joint such as the high and strong stud bolt specification, connection plate thickness and stud bolt arrangement etc. Further more, this paper discusses the main cause of the stud bolt group appearing slippage and the most carrying capacity calculating method of the high and strong stud bolt when the stud bolt group appears the slippage damage, and contrasting the calculating data with the carrying capacity design value provided by code, illuminating the reason why the code's value is conservative.3. On the basis of the experiment data, analyzing the each component's the load-bearing state and distortion state in the joint area, researching the corresponding relation of connection plate restrict moment to outer loading and connection plate restrict moment to beam- end rotation corner, analyzing the restrict capacity of connection plate moment and the bearing moment's mechanism of the joint area inside the wall . Further more, this paper researched the complex stress state nearbythe steel beam's stud bolt aperture, discussing their local intension when the joint is damaging, there are some reference meanings for engineering design.4. Simulating the experiment process using the finite element program, and contrastively analyzing the experiment data and simulating data, confirming the application range of the finite element program in the structure experiment. Further more, this paper analyzed the wall's stress distributing state by the finite element program, it provides a reference for concept design in the practical engineering.Finally, providing some unresolved problems on the basis of concluding the whole paper's works.
