A tent includes a shell, a frame including at least one flexible, resilient pole for extending over an exterior of the shell in an arch shape and for holding the shell up in an erect configuration in which the shell encloses a living space. The pole includes a plurality of sections, each section bounded by first and second points on the pole. A truss system includes a plurality of chords for tending to hold the pole in the arch shape. Each chord includes at least one tension-taking web extending along the exterior of the shell generally along a line from the first point to the second point of one of the pole sections to inhibit movement of the first and second points away from one another whereby the chords tend to hold the pole in the arch shape and stabilize the tent.
