IMPLEMENTATION AND APPLICATION OF NON-ITERATIVE DESIGN PROCEDURES FOR REINFORCED CONCRETE CONTAINMENTS SUBJECTED TO COMBINED AXIAL FORCE AND BENDING MOMENT

摘要

A non-iterative design methodology for reinforced concrete containments subjected to combined axial force and bending moment is presented by Jung et al. (2012). A prerequisite to the proposed methodology is a known four-sided polygon region where a demand pair is located on the non-dimensionalized interaction diagram. The purpose of this paper is to identify and present an efficient numerical scheme that can be used to locate a capacity polygon where a particular demand point is located. The identified scheme is the key element to the implementation of the non-iterative reinforced concrete design methodology. A portion of a Reactor Containment Building (RCB) is used as a representative design section to demonstrate the efficiency of the developed design methodology to handle a large number of design cases.
