Fn = Nominal shear strength, Fv = 0.50 Fu for bolts when threads are excluded from shear planes, i.e. A325-X or A490-X In addition, when a bolt carrying load passes through fillers or shims in a shear plane, the provisions of LRFD section J3.6 apply. Values of design shear strength for A325, A490, and A307 are listed in LRFD Table 7-10 7. FIELD WELDING PROCEDURES - NCDOTAWS D-1.5 Section 3.2.4 Reentrant corners of basemetal cut edges - shall be formed to provide a smooth transition with a radius of not less than 25mm [1 in] that meets the adjacent edges without offset or cutting past the point of tangency. The reentrant corners must be formed by
Contactor A1 is for the back gauge to move away from cutting edge. Contactor A2 is for the back gauge to move towards cutting edge. Motorized back gauge. The back gauge serves as a gauging device. When the plate to be cut is pushed into the Shear, it is stopped by the gauge-bar. Modern Steel Construction steel questions or comments of the Specification, separate minimum edge distances were given in Tables J3.4 and J3.4M for sheared edges and for rolled or thermally cut edges. Sections J3.10 and J4 are used to prevent exceeding bearing and tearout limits, are suitable for use with both thermally cut, sawed and sheared edges, and must be met for all bolt holes. Multi-girder composite bridges - SteelConstructionfoThe use of plate girders gives scope to vary the girder sections to suit the loads carried at different positions along the bridge. The designer is free to choose the thickness of web and size of flange to suit the internal forces at different positions along the length of the span, though it must be remembered that too many changes may not lead to economy, because of the additional
A plate girder is a deep built-up beam consisting of plates (or plates and angles) meant for carrying heavy loads on large spans. For heavily loaded girders of large spans single I-sections even with cover plates do not provide the necessary moment of resistance and shear resistance. A rolled steel beam may be suitable for spans not exceeding Structural Steel - BS EN 10025 S355 and S275S355, S355JR, S355J2, S355J2+N steel in plate, round bar, flat bar and blocks. S355 steel is a low carbon steel whose specifications offer high yield strength. The average minimum yield for S355 steel is 355 N/mm² giving its name:S355. BS EN 10025 S275 & S275JR supercedes BS4360 43A and 43B. S355 sheet/plate can also be flame cut to a profile US3650849A - Perforated shear-plate for dry shavers This invention provides a perforated shear-plate for dry shavers, made of a soft, hardenable steel foil and comprising bridges which form a network between the holes and which have edges forming the rims of the holes, the edges being flanged and ground and the material in the region of the edges having a submicroscopic, extremely hard martensitic structure containing residual austenite.
