A structural support member is disclosed. It has at least two longitudinally extending flanges spaced apart from one another by an assembly comprising a web and at least one reinforcing member. The web comprises at least one wave-shaped web portion arranged perpendicularly to the flanges, and at least one apex of the at least one wave-shaped web portion comprises at least one reinforcing member. The structural support member is typically formed as a beam.

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 splice joint of a main girder of a crane, the main girder including at least two longitudinal main girder parts to be connected to each other by their ends and each having a central web which includes at least one web plate, longitudinal upper and lower flanges, the lower flange protruding from the central web to both sides thereof. The splice joint includes a plate-like tongue-and-groove joint, the tongue-and-groove joint including a tongue fixed to the central web of a main girder part, and a groove fixed to the central web of a second main girder part; and a lower flange joint receiving the bending forces of the splice joint. The tongue-and-groove joints are arranged reversed in relation to each other, and the location of the tongues and grooves on opposite sides of the web is reverse in relation to each other.

The innovation relates to a pool covering system that is usable as a flooring surface. The pool covering system includes brackets and support beams spanning the pool opening. The beams provide structural support to cross members and flooring placed on top of the beams. The pool covering system does not require significant drainage of the pool and does not damage the pool structure during installation and use.

Provided are a hollow composite beam using a dual-web and a construction method thereof. The hollow composite beam using a dual-web can secure space efficiency using a tendon installed in an internal space of a dual-web and can efficiently adjust a tensioning force using the tendon anchored by an anchoring wedge and a separable bolt, wherein the dual-web is formed as a web of a steel beam having a bottom flange on which a deck plate is supported.

A joint connection structure of a building framework includes a column assembly including a column and a pair of side plates attached to the column on opposite sides of the column and extending laterally outward from the column. A beam assembly includes a beam having an end portion received between the side plates. At least one of the column and the beam has an opening in an area between the side plates to provide access for bolting at least one of the side plates to one of the column and the beam. The opening is free of a fastener extending through the opening when the column assembly is attached to the beam assembly.
