Abstract:
Design of structures to resist abnormal loads such as earthquakes and explosions, one of the most important requirements to protect people and buildings and should be used for all types of structures. The deformation ability of reinforced concrete structure is dependent on the number and location of plastic hinges can be formed due to loads. In the present study, a unified approach will be developed to estimate the rotational capacity of plastic hinges in reinforced concrete structures applied to earthquake and blast loads. A unified analytical approach was developed to be a unified one used for both blast and seismic loads. A previously proposed explosion model was modified to be close to the standard moment-rotation curve of ASCE. The modification was based on the concept that the strain rate in the case of seismic loads is less than that of blast loads.
