A roof structure supporting a roof comprising a truss and a joist supporting the truss, the joist having two elongated wooden beam members on the bottom of the truss connected with beam tie members comprised of a pair of congruent truncated mirror image parallelograms forming hexagons with mutually facing and abutting portions. Each beam tie member is connected to outer sides of top and bottom elongated wooden beams and is adjacent to the next beam tie connected to outer sides of top and bottom elongated wooden beams. The tied beams allow use of smaller, less expensive beam members yet providing good truss support in a joist.

Wall systems and buildings having such wall systems are disclosed. Such wall systems include parametric mullions each of which is constructed from a plurality of interconnecting components so that the wall systems may be disposed much closer to the building frame than conventional wall systems. Such wall systems may include panels disposed to form convex or concave facades. Such wall systems may also include decorative features superimposed over one or more panels or extending outward from the facade surface. The parametric mullions may be formed into trusses which may be used as part of a wall system or independently of such wall systems.

A method including placing on a surface a first beam having a first end with a first clevis component opposing a second clevis component. A second beam, including a second end having a third clevis component opposing a fourth clevis component, is placed adjacent the first end on the surface. The first clevis component is connected to the third clevis component. A lifter is connected to the first end and the second end, which are lifted simultaneously from the surface while rotating the first beam and the second beam about the connector until the second clevis component engages the fourth clevis component. Connection between the second clevis component and the fourth clevis component then may be completed.

A computer program product comprising: accessing a model of a building, wherein the model is comprised of a plurality of assemblies, wherein the assemblies are comprised of a plurality of members; detecting the assemblies which are identified as roof trusses, wherein the roof truss is identified by the specific members and member internal interfaces and the member properties; analyzing the roof trusses to determine if a roof truss has an external interface with another roof truss; isolating the roof trusses and the plurality of members; and analyzing each of the members of the roof trusses which have external interfaces with other members, wherein the interface is analyzed to determine if the interface is conflicting, wherein a conflicting interface is one where the actual values of the members are inconsistent with a required value.

The present invention is a computer implemented method comprising: accessing a model of a building; isolating a set of roof trusses, wherein the roof trusses are comprised of members; analyzing each of the members and determining the actual properties of each of the members; comparing if the actual properties of the members are within a predetermined tolerance of a set of required properties for each of the members; and generating a list of all conflicting members.

A prefabricated pole barn including a truss assembly, a foundation assembly and a roof assembly is disclosed. The truss assembly includes specially made trusses made with galvanized square tubing or red iron tubing. The tubing helps to provide the trusses with added strength and stability. The design of the trusses along with a quickset foundation of the foundation assembly, particularly treated floor support poles of the foundation assembly, and a roof of the roof assembly help to provide with a quickly and easily assembled pole barn. The pole barn is further stronger, more stable and loadbearing in comparison to traditional pole barns using standard bar joist trusses made of wood.

A structural support system of paired top and bottom rails connected by a plurality of vertically-oriented brackets, for use in construction settings such as truss arrangements and staircases. The rails have elongated slots for receiving and retaining connectors of the brackets. For staircase arrangements, the upper rail further includes an upper elongated slot for receiving step supports, and at least two paired top-bottom rails are positioned laterally for a step to be secured to upper surfaces of the laterally-adjacent step supports. Spacers can be employed in any or all of the slots for providing a desired distance between brackets or step supports.
