This paper is concerned with investigating of the plastic behaviour on gap K-joints truss girders, made from thin-walled rectangular hollow section members. An experimental study was carried out a full-scale girder under concentrated load two central nodes. A numerical analysis using ABAQUS in order to clearly see this type joint and make comparison experimentation. will it possible examine att...

Thin-walled cold-rolled sections are used in the construction industry, especially roofing of large-span halls. The load-bearing capacity a thin-walled structure depends to large extent on details at point attachment and interconnection individual elements. Therefore, case structures, it is necessary use additional structural elements such as local reinforcement, stabilising elements, supports,...

ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. the importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. up to now, different materials such as z...
