Modes of failure Generally, with only one connection installed on each beam, all the beams are under-designed, and they appear to behave similarly because the insufficient number of connections leads to losing the composite action before any failure in the principal parts consequently the timber beam and concrete slab stay intact. The visualisation of the twenty-four bending beams according to their failure can be reduced to three main categories A, B and C illustrated in Fig. 17. Which are: A) Shear failure of the notch without remarkable effect on the composite action of the TCC beam.
