Web11 apr. 2024 · Hi, Eurocode 3 defines that if the design shear force is more than half the design shear resistance, then the combined effect of bending and shear is calculated by considering a reduced design strength. This reduced strength is calculated as f yr = f y × (1-ro). However, this reduction should only be made within the shear area. Web4 jan. 2024 · As a rule of thumb, an internal thread of a given specified size should have the same basic diameters as an external thread of the same specified size. This means that d_1 = D_1 d1 = D1, and d_2 = D_2 d2 = D2 where D_1 D1 and D_2 D2 are the internal …
