Abstract
The stress condition of inclined metal rods in the timber elements of the built-up section
Incoming article date: 08.02.2019The results of tests of a series of single-shear samples of joints of wooden elements on inclined metal rods (IMR), in which plain washers transmit the force between the rod and wood, are considered. The intended bearing capacity of the NMS-connection is determined by taking into account changes in SP 64.13330.2017. Theoretically and based on experimental data, the stress-strain state of an IMR connection and the stress state of inclined steel rods are considered. The prevailing factors in the stress state of inclined rods are established. The estimation of the bearing capacity of IMR-connections on the rods with plain washers performed.
