Abstract:
The influence of the amount of reinforcement, axial stress, and loading history on the displacement capacity of slender reinforced concrete walls is discussed. Observations are based on the results of 27 laboratory tests of isolated walls. All walls sustained lateral displacements in excess of 1 percent of their height without appreciable loss in strength.

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.

The purpose and scope of this special publication, which is concerned primarily with departures from and improvement upon code-based seismic design practice, are outlined. The broad underlying principles of wind and seismic design by current codes are discussed. Certain major deficiencies of current practice are pointed out. Comparative features of elastic and inelastic seismic structural response are outlined.

Mark Fintel and S. K. Ghosh
An alternative to the empirical code approach for earthquake-resistant design of building structures is proposed. The suggested procedure uses carefully selected earthquake accelerograms as loading and dynamic inelastic response history analysis to determine member forces and deformations. A number of analyses make it possible to design into the structural elements a desirable balance between flexural strength, shear capacity, and ductility. The amount of allowable ductility in a yielding member depends on selected serviceability criteria and on the deformational capacity of the member. The design approach makes it possible to predetermine the sequence in which inelasticity spreads to various designated structural members. A structure needs to be provided with special ductility details only in the predetermined hinging regions.
