Assessment and Refurbishment of Steel Structures


Introduction
Increasing economic and ecological pressure on the exploitation of natural resources nowadays significantly influences the aims of civil engineering. Therefore the need for reconstruction work and maintenance of engineering structures is now increasing considerably in comparison to the past.





Steel structures have an important role in civil engineering. In developing a strategy for the refurbishment of steel load-bearing structures, their positive characteristics should be noted: aesthetic elegance and prestige, economy (relatively low price of material with respect to durability and efficiency, short construction time and quick erection), flexibility (scope for reconstruction and reinforcement), environment (scope for further use of existing elements and component parts, recyclable constructional materials), safety (confidence in the use of homogeneous material, high visibility and easily accessible connections and joints) and technical convenience (easy combination with other materials, efficient anticorrosive and fire protection). Using the appropriate variant of a reconstruction method for a steel structure within the budgetary constraints can contribute significantly to the effectiveness of the solution.
