Experimental Study on Loading Capacity of Glued-Laminated Timber Arches Subjected to Vertical Concentrated Loads

Table 3

Experimental results.

Specimen number	Elastic limit state		Ultimate capacity state		Failure mode
	(kN)	(mm)	(kN)	(mm)
R1/6-C	14.00	12.92	37.50	47.88	a
R1/6-Q	12.00	13.04	28.00	38.45	c
R1/5-C	14.00	11.04	34.20	67.59	a
R1/5-Q	12.00	11.31	30.30	42.74	b

Note: Failure modes: a = tension failure at mid-span section, b = tension failure at quarter-span section (loading section), and c = tearing failure at arch foot.
