Abstract

In this article, an analytical model is developed for estimation of the maximum normal stress in a beam-column member subjected simultaneously to an axial load and bending moments. The analytical model is derived by defining the relationship between the maximum strain and average strains measured wirelessly from vibrating wire strain gages. On the basis of the experimental tests on a two-dimensional steel frame structure with beam-column members, the performance of the estimation model is evaluated by comparing the maximum strains directly obtained from electrical strain gages and the estimated maximum strains from the model. Using the model, a practical monitoring of the maximum stress in steel beam-columns is made possible by measuring three average strains at arbitrary locations.
