Stressed − skin semi ・ monoc k structuresare often used 飴 r the light structures $ uch as aircraft airframe cempenents . In these struc − tUres , the stresses are carried not only by the ftevming members but also by the surface membrane . Thcrc has recently been incrcasing use of moment resisting glulam timber joints in building structUres .
