ABSTRACT
ABSTRACT: This paper deals with a regression model to predict the partial-interactive ultimate strength of steel-concrete composite decks. A series of nonlinear partial-interaction analyses with various degrees of interaction and shear span ratios were conducted to formulate the partialinteractive problem. Through the regression analysis of these data, a regression model for the partial-interactive ultimate strength was proposed. The proposed model was verified by a test program. It is clear that a regression model based on a partial-interaction analysis is a powerful tool to predict the partial-interactive structural behavior of composite members.
