This thesis investigates the natural frequency and vibration induced stress of small bore power plant piping. Straight piping and piping with concentrated load, such as a valve, located anywhere along the span are studied. Four different boundary conditions of fixed-free, simple-fixed, fixed-fixed and simple-simple are investigated, as any single span piping may be approximated by one of these boundary conditions.
The results otained [sic] for frequency and stress coefficients in the case of straight piping are plotted. Plots of frequency factor and stress ratio for the piping with concentrated load are also presented.
The results obtained for the natural frequencies are compared with the available literature, and it is observed that they are in good agreement. In the case of single span piping with concentrated load, the natural frequency asymptotically approaches that of uniform piping as the concentrated load approaches zero.
