[en] The “Dimitrios Vikelas” athletic center in Ermoupolis of Syros, Greece, consists
of two buildings. Building B has a steel superstructure that was constructed
approximately 35 years ago. It was initially used as a boat shelter and
no design calculations were made. It contains steel columns with varying cross
section heights. The spans are bridged via trusses and I-beams. Significant
geometrical inconsistencies are noted among the existing steel connections
and failures have been recorded as a result of buckling in several beams and
bracings during the service life of the athletic center. The current study
presents an investigation performed in order to diagnose building structural
problems and propose strengthening and intervention measures. The goal of
this study was to improve the load-carrying capacity of the structure in order
to comply with the current design codes. Moreover, enhancement of the dynamic
properties of the strengthened structure was demonstrated using modal
analyses. The structural behavior was determined in a more precise manner
via non-linear wind time-history and incremental static analyses. The analytical
results explain the development of failures in the existing structure.
