The crushed aggregates stemming material controlled the fragmentation within a certain range. The K 98 values were lower (0.85–1.43 m) in comparison to blast stemmed with drill cuttings (1.5–1.92). Lowered fragment size due to crushed aggregate indicates effective utilization of gaseous explosive energy in fragmentation.

However, few experiments on large-size glulam bolted joints (section height of at least 600 mm) can be seen in previous studies, which may have a mechanical behavior different from that of small-size joint. Most engineering design methods for bolted joints are based on Johansen's yielding theory [20].
