Study of changes i̇n pole and column di̇smensi̇ons for the sake of strengtheni̇ng concrete structure i̇n places close to the fault

Research and explanation of powerful vibration of the earth within two branches of structur engineering (i.e. structure behavior viewpoint) and earthquake engineering (i.e. earthquake analysis viewpoint) are utmost impotance. It should be noted that in order to minimize the destruction caused by great earthquakes, the specification, generalization, and development of analystic viewpoints about the powerful vibrations of the earth, seems to be an urgent necessity. The earthquakes of close to the fault have special characteristics that make them distinct from the earthquakes of far from the fault onces. The earthquakes of close to the fault have higher acceleration rate and limited frequency (in high frequency quantity) than the earthquakes of close far from the fault ones. Graphs of these earthquakeshave high period pulses with powerful amplitude which are observable in the initial record of the quake. İn the Present research, the reinforcement of bending frame structures and the way of their implementation will be discussed. To study the reinforcement of the structures with bending frame system, four heights of 5, 6, 8 and 10 modellings are carried out; then, after the analysis of the data, using SAP 2000 software, the related diagram will be shown. Static non-Linear analysis will be carried out to evaluate the function of the structures (and then the structures are reinforced). Then dynamic non-linear analysis will be carried out to evaluate the function of the structures (and then the structures are reinforced). Then, non-linear analysis with accelerate graphs of close to the fault and far from the fault will be carried out and the result of the analysis, resulting from the earthquakes of far from the fault and reinforced and non-reinforced structures will be analyzed with special regards to the place shifts and basic cuts.
