Design considerations for rail post anchorage into concrete

Jun 07, 2019  When rail post spacing exceeds 1.2 m (4 ft), the 0.73 kN/m force will govern it. These loads should be transmitted to the post anchorages and from there into the substrate. The choice of anchorage configuration and the substrate—curb, slab edge, etc.—affect the transmission of these loads. Figure 4: Embedded rail post detail, according to ...
