In order to compare the different states of openings, FEM is generated to illustrate the capacity of beams. The states are fully demonstrated to optimise a more economical and safe plan compared with various measures of strengthening.Keywords: Welded section; openings in web; beyond limitation of code; FE modelling in ABAQUS; Capacity analysis; measures of strengthening
