Microcomputer aided design for reinforced concrete frames subjected to seismic loads
This study presents a design procedure for reinforced concrete frames based on nonlinear dynamic analysis. The design procedure consists of four basic steps: (1) preliminary design based on member forces obtained by linear elastic analysis with equivalent static loading as prescribed by design codes, for example, the UBC code; (2) nonlinear dynamic analysis; (3) checking of damage of structure; (4) redesign of the structure if necessary. The establishment of this design procedure required the development of the following: (a) a microcomputer program for the nonlinear dynamic analysis of R/C frames subjected to strong earthquakes; (b) design aids, if the redesign of the structure is necessary. The first group of design aids consists of charts for steel reinforcements as functions of curvature ductility. A second group of design aids provides some guidance to choose curvature ductilities of members for selected structural displacement ductility. The software was designed to have: (a) file-oriented input data; (b) nonlinear dynamic analysis; (c) capability of displaying plots of: (i) undeformed structural geometry; (ii) ground acceleration input; (iii) nodal displacement; (iv) deformed structure; (v) finite plastic regions and damage ratios.
