Empirical Shear Force Capacity And Stiffness Model Of The Cross-Formation Screw Connections In Timber– Concrete Composite Structures

The connection between the two materials has a significant impact on the stiffness and shear force capacity of Timber Concrete Composite (TCC) structures when they are in flexure. Due to some shortcomings in Eurocode 5 (EC5) and existing predictive strength and slip modulus models of screw connectio...
