Title: Earthquake Ground Motions

Author(s): Stuart D. Werner

Publication: Symposium Paper

Volume: 127


Appears on pages(s): 21-66

Keywords: earthquake-resistant structures; earthquakes; elastic properties; geology; structural design; Structural Research

This chapter summarizes fundamental concepts pertaining to the development of seismic input criteria for inelastic design of reinforced concrete structures. The chapter is organized into five main sections that describe concepts related to earthquake phenomena; ground-shaking characterization, geologic factors, and measurement; and the three principal approaches for defining seismic design spectra, and motion-time histories. Compilation of the information contained in this chapter was completed in early 1988; therefore, the concepts presented in the chapter are based on earthquake ground-motion data, results, and procedures developed up to that time.
