DEMO CALCULATOR : Beam Natural Vibration Frequency [DEMO] ±
Plot And table DEMO Calculation : Calculate beam damped and undamped lateral natural vibration frequency for general beams (user defined properties - no axial load). Beam unit mass and EI are user defined. Select the end type, and vibration mode number (modes 1 to 5). The effective length factor should be used for beams on a soft foundation such as soil, where the beam ends are poorly defined. For defined beam ends, such as structures, the effective length factor should be set to one (fe = 1). The damping factor = 0 for undamped vibration, and 1 for critically damped vibration. Use the Result Table option to display a table of the natural frequency versus either mode number, or end type. Use the Result Plot option to plot the natural frequency versus beam length and mode number, or beam length and end type. The Fix-Fix and Free-Free modes have the same natural frequencies, but different mode shapes. Tool Input- endtype : End Type
