Objective of the workshop
A challenging task for engineers working in the field is the development of an efficient and economical retrofitting system for the increase of load capacity in existing structures due to increased live loads. Upgrading the design load of the structure by replacing its structural members is often more expensive and time-consuming than the rehabilitation of a deteriorated structure. The replacement of a structural member typically leads to prolonged service interruption compared to retrofitting, which usually takes minimum installation time, or in case the retrofitting techniques are in situ (both casting and installation), the service interruption may be avoided. Although the strengthening method using the installation of steel plates over the atrophied steel structure (parent member) is available, the shortcomings in its adaptability reduce the effectiveness of such an approach.
