  • Masonry arch bridge design in STAAD.Pro using plates

    Hi, I have modelled an arch bridge in STAAD.Pro. I used 2D plates to model the bridge. Supports are pinned. The bridge is masonry, and it should not have any bending moments in the arch section. All axial stress should be compressive. I get all the…

  • RE: Simply supported Pedestrian bridge with two tube arch at both sides

    1- Arches are typically simplified into a series of line segments. Curved members are possible in STAAD.pro (though the curvature needs to be circular arcs) 2- If a member is not to be part of the analytical model is should just be left out. A member…

  • RE: Arch Culvert in STAAD pro

    Keep in mind that in a true catenary arch under self-weight, the shear and bending is essentially zero as the force is carried almost exclusively by axial compression. Since your arch is kinked you'll see some spikes in the force diagrams near these joints…
