Abstract:
An experimental program was carried out to investigate the behavior of ferrocement bolted moment-resisting joints. Eighteen ferrocement moment joints and four control ferrocement plates were tested under third-point flexural loading. The moment joints were fabricated by joining two L-shaped ferrocement elements with bolts. The parameters investigated were the number of mesh layers, the corner distance of the first bolt, the number of bolts, and the moment modes (closing corner and opening corner modes). Results describing the load-deformation response as well as the failure mode are presented. As expected, the joints failed by premature cracking along the corner section of the L-shaped elements. The bending capacity of the joint ranged from 36 to 90 percent of that of the control plates, depending on the test parameters. The joint performance was improved by more than 50 percent when a fillet was added, and the failure crack was moved from the corner to one of the legs. The fillet was more effective for the elements subjected to the opening mode moment than the closing mode moment.
