Abstract
The characteristic strength values for compression perpendicular
to grain as they appear in EN 338 (structural timber) and EN 1194
(glulam) are currently up for discussion. The present paper
provides experimental results based on EN 1193 that may assist in
the correct assignment of such strength values. The dominant
failure mode of glulam specimens is shown to be fundamentally
different from that of structural timber specimens. Glulam
specimens often show tension perpendicular to grain failure before
the compression strength value is reached. Such failure mode is
not seen for structural timber. Nonetheless test results show that
the levels of characteristic compression strength perpendicular to
grain are of the same order for structural timber and glulam. The
values are slightly lower than those appearing in EN 1194 and less
than half of those appearing in EN 338. The paper presents a
numerical analysis to prove the significant role of tension
perpendicular to grain stresses in the failure mode of the glulam
specimens.
