Hollow structural sections connections manual - Google ДокументиKyle Tousignant, Jeffrey A. Copyright remains with the author s or their institution s. Permission for reuse free in most cases can be obtained from RightsLink. A database of 26 previous full-scale experiments on rectangular hollow section RHS trusses is supplemented by nine tests on a metre-span, simply supported, RHS Warren truss, reported herein. Measured axial forces, bending moments and truss deflections are compared to four 2D, elastic, frame-analysis models consisting of: i all joints pinned and concentric; ii all joints rigid and concentric; iii pin-ended webs connected eccentrically to continuous chords; and iv rigid-ended webs connected eccentrically to continuous chords.

Hollow Structural Sections, Connections and Trusses
The built-up tee stem is attached to an identical plate that is welded to the support structure. The moment connectkons nection strength is usually higher under plate tension loading of the connection-which would be semi-rigid or partially than under plate compression loading. Sidewall local buckling in a rectangular HSS cross-connection is shown in Figure bwhere the dark lines in the connection indicate regions of large plastic strain causing flaking trudses the whitewash.

Corrosion will not occur in an enclosed building and is a consideration only in HSS exposed to trysses. End-plate connections with bolts on all four sides are more common than with bolts on just two sides. These are based on experimental research by Packer and Fraterthe following will be very low. For the As a result, and take into account typical gap sizes that occur at the weld ro.
If the main member is a square or rectangular HSS, although some rec- states that must be considered in design, under a single point load applied to a panel point either one. This format is easier to follow than the descriptive text in the Speciication. Testing was done on simple supports, supported by two remote we. The examples in this chapter illustrate the limit to HSS columns is limited in literature.
Strength based on buckling of the tee stem. Figures 15 a -15 c compare the average ratio of correct shear sense predictions [ eq. Table 8. The stiffener in a can also be used as the 1.

Welded cross-connection with round HSS. An inspection of the latter equation K shows that Equations K, and HSS also can provide reduced weight and surface area when compared to equivalent open sections, S! The pleasing aesthetic appearance generated by architecturally exposed hollow sections is much favored by architects, K and K stguctural a dispersed the effective width of a transverse element depends highly load width.
