Dynamic Calculation of Frames with Distributed Mass on the Action of Harmonic Load
摘要
This chapter provides the definition of static and dynamic prerequisites for the calculation of frames and rods with distributed mass as systems with an infinite number of degrees of freedom. The calculation of such frames uses the displacement method whereby the frame is transformed (converted) into a system made up of single-span beams with the introduction of additional links at the nodes with different boundary conditions. A brief overview of the theory of dynamic calculation of frames by the displacement method is provided along with a presentation of calculation sequence. A table of correction coefficients for support reactions and an example of calculating frames using the displacement method for vibration loads are given. The appendix at the end of the book contains tables with numerical values of correction coefficients for the dynamic calculation of frames.
