Description of the research topic:
In the Hungarian construction industry, there have been several economical punching reinforcement systems that have been successfully applied for decades, but in the lack of experimental evidence, with the spread of modern internationally approved systems, they are going to lose ground on the market. These systems can be easily installed, and compared to expensive import products, have low material costs.
Despite the good experience, they are not competitive according to the new standards. The main reason is that these kind of punching reinforcements are placed between the two main reinforcement layers, and their efficiency is not proved by experiments. The problematic zones are the punching-to-flexural reinforcement connections and the inner end-zone of the punching reinforcement.
The aim of the research is experimental analysis of the zones cited above, measurement and modelling of the resistance of the slabs with these individual reinforcements. Furthermore, the aim is to optimize the reinforcement and to meet the requirements of the latest standards.
The second part of the research is cost and shape optimization of the headed studs with equivalent strength properties.
The anchorage effectiveness of the bar will be experimentally tested using single bars, headed bars and bars embedded into concrete.
The goal of the research program is to analyse individual and improved punching reinforcements, which have not been experimentally verified before. The planned schedule of the research is the following:
1) Literature overview, definition of the detailed research program.
2) Design and execution of a detailed design program to analyse the effect of the most important parameters.
3) Evaluation of the experimental test results, revision of the existing punching models.
4) Extended parametric study by non-linear FEM modelling of the punching zone.
The research program is linked to the tender projects of the Department of Structural Engineering and its industrial partners.
