The CD also has examples of a transverse plate on a rectangular HSS a longitudinal plate on a round HSS and HSS braces with end gusset plates as well as examples of the design of cap plates base plates and end plates on HSS members.

Continuous Beam at Column Splice HSS column is interrupted at continuous beam For lightly loaded columns stiffener plates can be used to transfer axial forces Heavy loads may require a split HSS on either side of the beam web.

ERW HSS beam of Fy 50 ksi ASTM A500 Gr. Select a rectangular ASTM A500 Grade B HSS beam with the span of 21 ft.
The project architect would like to use HSS members for the exterior columns of the building because these would work better with the wall assembly that he is envisioning. The steel beam design worked example elaborates the design of a simply supported beam having a uniformly distributed load. Steel Construction Manual Design Examples V151.
C spans 18 feet and supports a uniformly distributed load of 500 pounds ft. Design a base plate given that the column dead load is 100 kips and live load is 150 kips. Base plate material is A36 steel and concrete compressive strength is 3 ksi.
The following examples are taken from one connection hss design moment example ii. As mentioned before every beam-column design example that I have done in the past or have come across onlinein books have used wide flange steel members. From AISC Specification Section G5 if the exact radius is unknown h shall be taken as the corresponding outside dimension minus three times the design thickness.
Example 11 - Design of a Column Base Plate. Therefore we can reduce the above combinations to include only these loads. Therefore this needs to be checked ΦRn 06Fyt2tf2Bep Bep 10bfBt 328 bf ΦRn 793 k 51 k OK 12 Directly Welded Connection Example 132014 5.

Condensed for Use in First Semester Structural Steel Design Classes. Beam flange should be wider than HSS.
Due to lack of space these design tables were omitted in the 11th Edition 2016. The loads include a uniform dead load of 015 kipft and a uniform live load of 04 kipft. Example 2 - Analysis of steel beam-column braced against sidesway Example 3 - Analysis of steel beam-column braced against sidesway Simple Connections Example 1 - Checking bolt spacing edge distances and bearing for a bolted connection Example 2 - Calculating the strength of a bolted connection by checking bearing and shearing per LRFD and ASD.
The beam is considered as simply supported and the design data for calculating the bending moment and shear forces are given below. Fy specified minimum yield stress of HSS member material MPa. Six short worked examples illustrate the verification for typical design situations.
B to support a concentrated axial compressive load of 120 kips. Total DL LL. Torsional constant of an HSS is 200 times that of an open section HSS Wide Flange Torsion Torsion Example.
8 x 8 x 516 HSS Weight 3184 lbsft Example II Select the lightest square ERW HSS column of Fy 46 ksi ASTM A500 Gr. The beams will see some torsion and thus I would like to make them closed HSS or a W-shape with plates welded to either side to close them up which is much more fabrication. The beam is braced at the end points only.
Greatest fitted to the colder months wine nails are all of the rage this time. A W10 x 49 column is supported by a concrete pier whose top surface is 19 inches x 19 inches. Overall width of rectangular HSS branch member in a truss connection.
Summary 1 11 Torsion of beams In most steel-framed structures beams are subject only to bending and not to torsion. 12D L 4. In buildings beams are usually hot rolled I or H sections proportioned for optimum bending performance about their major axis.
085B bf B-2t. Beam with large span L20m B. Great for the winter months these wine and white nails are straightforward to replicate and search incredible on clean up short nails.
Online Design Tool. Structural Design of High Strength Steels 5. Directly Welded Connection Example HSS shear yieldingpunching Applicable when.
For rectangular HSS in shear use AISC Specification Section G21 with A w 2ht per AISC Specification Section G5 and k v 5. The Example was calculated in American unit system. The compression flange is braced laterally at the ends.
Hss beam design example. Web area 8 overall width of rectangular HSS 8. 12D L 6.
D outside diameter of round HSS member mm. 09D By inspection load case 2 will create the largest load. The AISC Committee on Manuals prepares design examples to illustrate the application of the provisions in the AISC Specification for Structural Steel Buildings.
New beams are being placed inside of existing columns. Figure 1 Steel Design Series SDS-7. The examples in this Guide conform to the 2005 AISC Specification for Structural Steel Buildings.
HSS weight 1732 lbsft Example IV A simply supported 10 in. 12D 16L 3. The largest effective length KL is 14 feet.
My first attempt is to go with the HSS so I am trying to find the best way to connect the HSS to a W-shape column. Refer to part 3 Column Design. This load case is selected as shown in the table above.
Beam load tables for rectangular HSS have been published in the Handbook of Steel Construction up to the 10th Edition 2010. 12D L 5. HSS Bolted Connections Introduction Steel hollow sections have until recently been used almost exclusively for truss girders bridge girders and in recent examples columns taking advantage of their inherent properties when axially loaded in tension and compression.
- HSS S420 S460 S690 A. In this case WF beam shear reactions are imparted onto the HSS column below in local bearing. Bp width of plate measured 90 degrees to the plane of the connection mm.
Limit the live load deflection to L240. B overall width of rectangular HSS member measured 90 degrees to the plane of the connection mm. We are designing the beam for gravity loadsdead load D and live load L.
Rectangular HSS may be required to fit base plate on beam. The complete set of design examples includes 166 example problems. One example of this connection type is a wide flange WF beam framing over an HSS column in which the bottom flange of the WF beam is bolted to a cap plate which is welded to the top of an HSS column Figure 1.
They are now being re-introduced as part of the CISC Steel Design Series.
