  1. Average increase of shear resistance by a web connector is 157.96 kN-139.10 kN = 18.86 kN.
  2. Average increase of shear resistance by a flange connector is (175.66 kN-139.10 kN)/2 = 18.28 kN.
  3. *Denotes invalid data because of fast loading, this data is not involved in subsequent analysis.
