ABSTRACT
The types and basic methods of reinforcing steel load-bearing structures are shown
in Figure 4.1. From a constructional point of view these methods can be divided
into these classes:
(a) Reinforcing by enlargement of the original cross-section of elements, rein-
forcement of joints and connections
(b) Reinforcing by changing the static scheme, insertion of additional members
and stiffeners in order to reduce stresses in the original structure
(c) Combined method of reinforcement, in which the static scheme is changed
and cross-sections of individual elements are enlarged.
