4b)
The limit state method of design overcomes many of the disadvantages of permissible
stress and load factor methods. This is done by applying partial factors of safety, both to the
loads and to the material strengths, and the magnitude of the factors may be varied so that
they may be used either with the plastic conditions in the ultimate state or with the more
elastic stress range at working loads. This flexibility is particularly important if full benefits
are to be obtained from development of improved concrete and steel properties. Spell out
the drawbacks and disadvantages of the two methods.
