Abstract:Wrought‐iron and mild‐steel riveted lattice beams are well‐represented in the metallic construction heritage of 1850‐1930. Many rafters and purlins of roof structures of train sheds or market halls are made of flat and angle bars assembled with single‐riveted joints. During retrofitting operations, those beams are often reinforced to prevent them from buckling. However, the assessment of the buckling risk depends strongly on the modelling assumptions regarding the out‐of‐plane rotational stiffness of the rivet… Show more
