Abstract

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..
