A portable shelter is provided for sheltering materials or human occupants at a remote location. The shelter includes, among other things, a flexible cover and a supporting frame. In operation, hinged members that are part of the frame are used to support a first portion and then a second portion of the shelter. Before the frame is raised up, the people who are constructing it can easily reach the top parts of the shelter without a stepladder or the like. By avoiding the need for a stepladder, the overall size and weight of the assembled components that have to be transported to the remote location can be reduced, and the shelter can be constructed more quickly and easily. Hinges, purlin connections, and corner closure systems for the shelter are also disclosed.

1. A method of constructing a portable shelter, said method comprising: unfolding plural, multi-piece, arcuate frame assemblies to partially-extended configurations;bracing the frame assemblies together;subsequently, unfolding first portions of the frame assemblies and raising a corresponding first portion of the portable shelter; andunfolding second portions of the frame assemblies and raising a corresponding second portion of the portable shelter, the first and second portions of the frame assemblies being at opposite ends of the respective assemblies; andwherein the method of constructing the portable shelter further comprises the step of locating a flexible cover over the frame assemblies, and wherein the step of locating the flexible cover over the frame assemblies occurs after the step of unfolding the frame assemblies to the partially-extended configurations, and wherein the step of locating the flexible cover over the frame assemblies occurs before the steps of (1) unfolding the first portions of the frame assemblies and raising the corresponding first portion of the portable shelter and (2) unfolding the second portions of the frame assemblies and raising the corresponding second portion of the portable shelter. 2. The method of claim 1, wherein the step of unfolding the assemblies includes the step of extending at least four arch assemblies to partially-extended configurations. 3. The method of claim 2, further comprising the step of causing the frame assemblies to be essentially parallel to each other.
