An application of the strength-related performance verification method to steel double arch-rib structures in cyclic loading

Abstract

Elasto-plastic large deflection static/dynamic analysis using beam elements is one of the most practical, yet reliable tools in strength-related stability/seismic design methods for steel structures. Among them, the strain-based seismic verification method (SBSVM) is believed to be versatile and thus applicable to not only steel bridge piers, but also a variety of steel bridges such as arch, truss, cable-stayed bridges etc. However, some criticisms against the method have been raised recently by some researchers. The present paper is intended to clear up the misunderstandings by presenting the full procedure of SBSVM using steel large scale double arch-rib model structures tested in a research laboratory of a bridge fabricator.
