This type of connection is commonly found in Girder Trusses, particularly Bridge Girders. The horizontal beam(s) may be orientated with the flanges top and bottom or rotated through 90° with the flanges to the side. The advantage with the latter is that the beams and bracing members can be of the same section making it […]

These heavy-duty bracings are generally designed to work in compression, with the tensile stress being considered insignificant and largely ignored. Such bracing is often used in structures which are subject to high lateral loads, particularly in areas which are subject to seismic activity. The joint ends should be faced for full bearing, but this can

Theses heavy-duty bracings are generally designed to work in compression only, with the tensile stress being considered insignificant and largely ignored. Such bracing is often used in structures which are subject to high lateral loads, particularly in areas which are subject to seismic activity. The joint between the flanges must be true and square in

The following typical connections apply to –I- or –H- profile bracing which may be subject to tension or compression. The flange angles are bolted to the gusset plate and site-bolted to bracing member on erection. This all-bolted option allows for some fabrication alignment (but not much) as the bolt clearance holes will allow for some

The following typical connections apply to –I- or –H- profile bracing which may be subject to tension or compression. The flange plates are slotted to ‘wrap around’ the gusset plate and shop welded in position. The bracing members are then site-bolted to the flange and web plates. Any misalignment may be compensated for by allowing

The following typical connections are for channel section bracing which may be either single or doubled back-to-back, being the more common. This type of bracing usually requires a double row of bolts equally spaced about the centre-line of the bracing member. The general rules-of-thumb for the spacing of the battens applying to Angle bracing may

The following typical connections are for double (starred) angles connected by means of Gusset Plates – To ensure the angles work together as a single unit they should be joined together by means of battens, which are fabricated spacers placed at intervals along the bracing member’s length. Star-Battens will be looked at later in this

The following typical connections are for single angles connected by means of Gusset Plates: The bracing angles are set out to a common Work Point located at the intersection of the centre lines of the beams, columns and bracing members. Other options for locating the Work Points can be found at Vertical Bracing – Setting

Here, we’ll be looking at the setting-out procedure for Concentric vertical bracing using gusset-plates, the general principles will apply to all bracing configurations irrespective of member sizes. Concentric bracing implies that the Work-Points are derived from the center-line intersections of the beam, column, and bracing member. The center-lines represent the neutral axes of the members,

The Vertical Braced-Frame is the most straightforward and efficient vertical stabilizing system. It’s fairly straightforward to resolve, and equally straightforward to fabricate and erect. Braced frames are flexible in the sense that they can be adapted to suit almost any conditions and a wide variety of load combinations. Bracing is also the most economical stabilizing

Vertical braced-frames are the simplest and most effective of the stabilizing options, they are relatively straightforward to analyze, economic to fabricate, and can be erected in a relatively short space of time. Hence, Braced-Frames are without doubt the most popular and efficient stabilizing option and will account for a great majority light commercial and industrial
