Analysis of supported steel frames with rigid and semi-rigid connections

The use of a bracing system for controlling lateral displacement of frames, especially in case of semi-rigid connections, is analysed in the paper. The results indicate that various effects on the stiffness and ductility parameters of structures can be achieved with different bracing methods by the use of rigid connections instead of semi-rigid connections in supported frames. Moreover, the progressive instability of structures can in some cases be influenced
