Fire-Resistive Joint Systems
This standard is issued under the fixed designation E 1966; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
Joint systems are positioned in joints, voids, gaps, or other discontinuities between or bounded by
two or more supporting elements. Normally such openings are denoted as “linear” because the length
is greater than their width—defined by a typical ratio of at least 10:1 as in practice. Joints are present
in buildings as a result of:
(i) Design to accommodate various movements induced by thermal differentials, seismicity, and
wind loads and exist as a clearance separation.
(ii) Acceptable dimensional tolerances between two or more building elements, for example,
between non-loadbearing walls and floors.
(iii) Inadequate design, inaccurate assembly, repairs or damage to the building.
