A modular rafter assembly is provided. The modular rafter assembly includes a plurality of different types of rafters having varying lengths and that are adjustable to varying pitches. The modular rafter assemblies disclosed herein utilize a plurality of rafters in varying lengths, widths, and using varying thickness plates to allow for differing load calculations. Each of the rafters also includes a pitch adjusting mechanism that allows adjustment of the pitch of the rafter depending on the desired roof pitch.

A strut including an elongated beam portion and a connecting end portion. The elongated beam portion is a tubular structure having an external circumference, the connecting end portion is integral with the elongated beam portion, has a folded and flattened end portion of the tubular structure, and where diametrically opposite inward fold lines meet between flattened parts the end portion of the tubular structure. The resulting connecting end portion includes four material layers and the connecting end portion has a width transverse to a longitudinal centerline of the connecting end portion.

A construction formed of column and a beam, where the beam has top and bottom flanges coupled to the column by a lateral bracing system, and a web between the top and bottom flanges. The lateral bracing system may include a column-mounted plate including a horizontal portion and a vertical portion, the vertical portion affixed to the column. The beam may be coped at top and bottom edges of the web to prevent binding of the beam flange with the column-mounted plate upon rotation of the beam relative to the column.

A clearspan structure including component systems, and methods of forming a clearspan structure including component systems, for mitigating hazards to personnel or equipment from explosions, fires, toxic material release, and other hazards in hazardous locations. The exemplary clearspan structure is also capable of withstanding environmental conditions such as snow loads and wind. The exemplary clearspan structure is, for example, a tent or fabric structure which includes a plurality of frame members forming a support system for the clearspan structure, and fabric roof portions and walls for enclosing the clearspan structure.

A shear beam-column connection includes a first beam, a first tapered bolt having a non-threaded portion and a threaded end portion, and a column including a first wedge slot block. The non-threaded portion of the first tapered bolt is fixedly secured, e.g., by welding, to the first beam. The wedge slot block includes a cavity for removably receiving the non-threaded portion of the first tapered bolt. The first wedge slot block is fixedly secured to the column, e.g., by welding. The first beam can be secured to the column by positioning the first beam adjacent the column such that the non-threaded portion of the bolt is inserted into the cavity. A nut can be threaded to the free end of the bolt to further secure the beam to the column.

The present disclosure generally relates to an elongated section (101) for construction structures (300). The elongated section (101) comprises a plurality of sides (102), each side (102) comprising a first retaining channel (104) and a second retaining channel (105) adjacent a respective corner (106) of the elongated section (101), the first and second retaining channels (104,105) being a minor image of each other. Each retaining channel (104,105) is configured for engaging a respective retaining member (201) for supporting a structural panel (301) between the retaining members (201). Each retaining channel (104,105) comprises a channel slot (197) extending perpendicularly into the side (102), the channel slot (197) for engaging a first end (204) of the respective retaining member (201); and a channel end (198) opposite to the channel slot (197) for engaging a second end (206) of the respective retaining member (201).
