The paper (Part I) discusses several basic problems concerning nonlinear modeling techniques of structural constituent members, which will be followed by another paper (Part II). These constitute a basis for idealizing a planar R/C frame as a nonlinear dynamic system for the purpose of simulating its inelastic behavior and further pursuing its dynamic collapse process during severe earthquakes. Specifically intended are these modeling techniques to bridge a fairly large gap lying between restoring force characteristics of each member under simple loading condition, which is directly estimated by experimental means (represented, for example, by a group of empirical equations), and those under more complicated condition in an actually loaded frame, which must be evaluated successively at each stage of structural analysis based directly on member-level properties. With the aid of these techniques, one can fully estimate the instantaneous nonlinear characteristics of overall structure, and trace the damage process of each constituent member under a given groudmotion disturbance by computational procedures. The discussions herein are developed with the main emphasis on the so-called 'inelastic beam model', which plays the most important role for attaining the above purpose.
