This experimental database encompasses parameters collected from 417 full-scale experimental specimens on mechanically jointed Timber Concrete Composite (TCC) beam and slabs subjected to short-term static bending tests. Parameters include general study details such as reference, test setup, specimen type, specimen count, and identification. Geometric properties are documented through span length, concrete and timber dimensions (thickness and width), and interface thickness. Shear connection information captured includes type of shear connector, shape, dimensions (depth, length, spacing), and arrangement patterns. Material properties recorded involve timber type, mechanical properties, and concrete type along with its compressive strength. Additionally, experimental observations cover reinforcement details, loading protocols, maximum load, maximum deflection, primary and secondary failure modes, and interface slip.
