In this study, the strain based lateral deformation estimation method for steel moment frames is presented. This method estimates the distribution of flexural moments by using strain data assumed which measured in the columns. If we know the distribution of flexural moments in the columns, we can estimate the lateral deformation of columns by using the slope-deflection method. The steel moment frame with the beam-hinge mechanism is used as an example structure. Zero-length rotational springs are considered to model joints.
