Recent Developments in the Design of Sealant Joints for Movement and Other Effects


Often, thermal movement and other performance factors are inadequately considered in the design of sealant joints. Performance factors that affect sealant joint design are described, including: thermal movement; moisture movement; live and dead loads; creep, elastic frame shortening, and shrinkage of concrete structures; and material, fabrication, and erection tolerances. Three calculation examples will be described for joints in new construction that accommodate movement: (1) an expansion joint in a masonry wall, (2) a joint between different building systems, and (3) a floor line expansion joint for a multi-story curtain wall and two examples for joints in remedial work: (4) a fillet (triangular) joint between a curtain wall and masonry wall and (5) a bridge joint for a precast concrete panel system..
