This study describes inelastic seismic design of piping systems considering the damping effect caused by elastic-plastic property of a pipe support which is called an elastic-plastic support. Though the elastic-plastic support is proposed as inela...
A software system to perform SCC crack propagation analyses for complex and realistically shaped structures consisting of dissimilar materials, such as weld metal, base metal, etc., under weld residual stresses is presented in this paper. The syst...
This study proposes a nonlinear vibration-response analysis method of cylindrical water storage tanks allowing coupling with the water in the tanks to be considered, and then demonstrates the proposed method can adequately simulate the experimenta...
In new measurement technique to propose, displacement by bending vibration of piping which vibrates using multiple laser displacement sensors is measured, and vibrational stress is obtained by calculating the strain produced from those displacemen...
A lot of damages have been reported due to fatigue of machine vibration during plant operation in nuclear power plant. The development of vibration measurement and stress evaluation that can operate quickly and easily is on demand. The purpose of ...
