Analytical Procedure for Timber−Concrete Composite (TCC) System with Mechanical Connectors
Abstract
:1. Introduction
2. Review of the TCC System and Connection Models
2.1. TCC System Model
- The beam is simply supported in one-way action under a uniformly distributed load.
- The cross-section consists of mass timber beams or mass timber panels at the bottom and a concrete slab at the top, with the possible presence of insulation layers or planks in between the timber and the concrete slab.
- The concrete and timber exhibit linear-elastic behaviour and remain in contact at all points along the beam with the shear connectors.
- The horizontal load transfer between timber and concrete is entirely performed by the linear-elastic perfectly plastic mechanical fasteners which are arranged symmetrically from the mid-span.
2.2. TCC Connection Model
2.2.1. Connection Strength
2.2.2. Connection Stiffness
