Summary

This chapter concerns vibration and shock in reinforced concrete structures, addressing how to design reinforced

concrete structures that will be subjected to vibration or shock, for example, due to a missile attack. The chapter is

intended to apply vibration theory to concrete structures. Section 14.1 describes the fundamental properties of

vibration theory. Section 14.2 proposes analytical models for reinforced concrete structures that are subjected to

flexure, shear, and dynamic loading. Section 14.3 discusses reinforced concrete beams under harmonic excitations,

including mechanical properties and designs for machine vibration. Section 14.4 indicates the step-by-step

procedure for designing reinforced concrete columns or walls that will be subjected to seismic loads or shocks,

respectively.
