To detect human survivors trapped in buildings after earthquakes by using structure-borne sound it is necessary to have knowledge of vibration transmission collapsed and fragmented reinforced-concrete buildings. In this paper, statistical energy analysis (SEA) considered for modelling seismically damaged, reinforced concrete, beam-to-column junctions where the connection between beam column mad...

The ability to predict the resistance of reinforced concrete (RC) structures progressive collapse as a result an interior column removal has become need in structural design. In general, three mechanisms characterize structure collapse, flexural action, compressive arch and tension catenary action. objective this study is investigate effects floor system configurations on collapse-resistance RC...

in this paper a new strategy is proposed to design a fixed-structure robust controller for a flexible beam.  robust controller designed by the conventional  loop­ shaping method is not appropriate for a beam because of its high order and complicated form. fixed-structure  loop shaping control in conjunction with particle swarm optimization (pso)algorithm  is used to overcome this drawback. the ...
