Behavior and Design of Corner Joints under Opening Bending Moment

Abstract

The results of an experimental program concerning the influence of reinforcement detailing on the behavior of corners subjected to opening moment are presented. The motive for this work was the damage observed in an actual lignite bunker. Three full-scale specimens were tested with different types of reinforcement in the joint. The first specimen had characteristics identical to the existing structure. The other two specimens were conceived and tested consecutively, each of them being detailed in accordance with the observations made during testing of the previous specimen. The mode of failure and the strains of the reinforcement measured in each case are discussed. Practical conclusions for design are drawn.
