چکیده مقاله
There are currently no guidelines in codes for calculating the composite action between a steel beam and a precast concrete slab using deconstructable high strength friction grip bolt HSFGB connectors in composite beams The design strength for this type of connector was considered in this study through extensive behavioral and statistical analysis As a result, the design of experiment DOE statistical technique utilizing the Plackett Burman PB design was used to screen the important and effective factors on the ultimate strength of HSFGB connectors Then, based on a database of all existing experimental findings and the results obtained from extensive three dimension finite element 3D FE models conducted in this paper and appropriate statistical analysis, a high precision equation for predicting ultimate strength is provided The proposed equation's acceptability and suitability to predict the ultimate strength of HSFGB connectors have been assessed and confirmed against statistical requirements The equation developed in this paper has higher accuracy in comparison to other proposed research relationships, according to the adequacy test and residual analysis
