When strengthening is going to be undertaken all failure modes must be evaluated. Strengthening a structure for flexure may lead to shear failure instead of giving the desired increased load bearing capacity. It should also be noted that not only the failure mode of the strengthened member is important. If a critical member in a structure is strengthened, another member can become the critical one. Because of changed stiffness in an undetermined structural system the whole structure must be investigated. The strengthening should also designed with consideration to minimize the maintenance and repair needs. When a strengthening is designed the consequences from loss of strengthening effectiveness by fire, vandalism, collision etc. must in addition be considered.

Retaining structures

Generally speaking, any wall that sustains significant lateral soil pressure is a retaining wall. However, the term is usually used with reference to a cantilever retaining wall, which is a freestanding wall without lateral support at its top. For such a wall, the major design consideration is for the actual dimensions of the ground-level [...]

INTEGRAL BRIDGES
Integral bridges in simple words can be defined as bridges without joints. Integral bridges are characterized by monolithic connection between the deck and the substructure (piers and abutments). They span from one abutment, over intermediate support to the other abutment, without any joint in the deck. Integral bridges have been constructed all over the [...]

The steel chimneys are of two types:

Self-supporting steel chimneys

Guyed steel chimneys.
