Effects of dynamic analysis on the prototype bracing and without bracing steel structure model. The vibration and the seismic movement induced by the earthquake. The modern growing world trend inclination towards earthquake resistant structures. That is the main peculiarity of choosing this research and carry forwarded experimental as well as ETAB software seismic analysis. The (G+4) storied prototype With And Without Bracing steel structure was modeled and tested with the help of the shake table. The shake table recorded seismic data from an accelerometer attached to each story of a prototype steel structure. The main aim of this dissertation to apply shakes table and software knowledge of dynamic analysis to study the effect of seismic events on prototype bracing and without bracing steel structure. Find out seismic properties like acceleration displacement, velocity, etc and according to the correlation of acceleration, displacement, velocity other seismic properties are predicted. The same prototype With And Without steel structure modeling would be done in Software and predicted all seismic properties like acceleration, displacement, velocity, and other seismic properties.
