The vibrations produced by earthquakes cause large horizontal forces in beam-column joints. If these exceed the limit values that joints can withstand, severe irreparable damage might occur. Experimental and analytical studies were conducted to determine energy dissipation capacity ductility of using “Self-compacting Concrete” (SCC) “Normal (NC) mixes containing various quantities steel fibres....

Structural health monitoring problems are studied numerically with the time reversal method (TR). The dynamic output of structure is applied, reversed, as an external loading and its propagation within deformable medium followed backwards in time. Unknown sources or damages can be discovered by means this method, focused reversed signal. theoretically justified time-reversibility wave equation....

In this research, three models of beam-column joint have analyzed under reversed cyclic loading by finite element method using ANSYS software. The first model was designed with a steel-reinforced (longitudinal reinforcement and stirrups), the second performed (GFRP) -reinforced in longitudinal only third (CFRP) only. behaviour loading, their load-storey drift envelope relationship energy dissip...
