Jason Ericksen, SE Kim Olson and Benjamin Kaan authored an eNews article titled “Practical Guidance for Concrete Filled HSS Columns” in September The article discussed some of the benefits of filling HSS columns with concrete, including increased strength and a potential reduction in fire protection requirements.
Practical Guidance for Concrete Filled HSS Columns By Kim Olson, PE, Technical Consultant to the Steel Tube Institute and Benjamin Kaan, PE, Associate, Thornton Tomasetti Filling Hollow Structural Section (HSS) columns with concrete is a means to achieve increased compression capacity through composite action.
Concrete Filled HSS Member $ Non-member $ Concrete-filled tubes provide several advantages over an equivalent steel or steel-reinforced concrete member.
Fire resistance, construction efficiency, and buckling resistance are all increased when a cementitious material is placed in the void of a tube. Hollow structural sections are produced in square, round and rectangular shapes to meet structural design • Composite HSS (concrete-filled tubes) Strength of Tubular Joints – 1st Edition (IIW, ) – 2nd Edition (IIW, ).

Concrete-Filled Hollow Structural Sections (HSS), an Unbeatable Combination Filling HSS members with concrete offers the most effective way to meet fire-protection requirements while achieving high compression strength, a smaller footprint, and the desirable aesthetics of exposed steel [ Page 2 of 3 ] Sponsored by Steel Institute of New York.

Two-way connections could be detailed so that the bolts or rods are slightly offset. Fig. 4: End-plate connections to a concrete-filled column, using long “through bolts”. Concrete Filled HSS and Lateral Loads. IngDod (Structural) (OP) 26 Feb 17 Greetings, I am trying to ascertain whether filling HSS columns with concrete in a steel two-story building would have any significant impact in reducing lateral deflections of the structure.
The idea is to use filled HSS tubes instead of a bracing system, since. The Patient Education Department offers a wealth of preoperative information and resources for patients undergoing spine surgery, total hip replacements, total knee replacements, hip resurfacing and total shoulder replacements.
The patient pre-op educational resources listed below are meant to help. There are lots of red flags here from the member sizes, welds, and no bending moment.

Generally, the HSS method is preferred to nominal stress approach for fatigue design of empty and concrete-filled tubular joints since the change in geometric parameters results in a. • HSS and Box Member Connections (Section NK) • Selecting Standard Connections from the AISC Manual (AISC Manual Parts 9 & 10) • Seismic Connection BMA Engineering, Inc.

Results from an experimental program on the behaviour of high strength concrete-filled steel hollow structural section (HSS) columns will be presented for three types of concrete filling.
A mechanics model is developed in this paper for concrete-filled HSS columns after exposure to the ISO fire standard, and is a development of the analysis used for ambient condition. The predicted load versus mid-span deflection relationship for the composite columns.
In addition, concrete-filled HSS sections have less exposed surface, as compared to regular I-shape columns, thereby reducing the cost of intumescent paint and other fireproofing.
Because of their closed shape, HSS columns are stronger than a wide-flange with the same weight, explains Kim Olson, P.E., technical consultant to the Steel Tube. For CHS and RHS welded joints under fatigue loading. Publication Date: Author: Zhao, Herion, Packer, Puthli, Sedlacek, Wardenier, Weynand, van Wingerde, Yeomans Editor: TÜV Verlag Edition: 1st.
Design Guide 7 For fabrication, assembly and erection of hollow section structures. Publication Date: The various factors that influence the structural behaviour of high strength concrete-filled HSS columns under fire conditions are discussed.
It is demonstrated that, in many cases, addition of steel fibres into high strength concrete improves the fire resistance and. publication provides guidance for moment-resisting joints, designed in accordance with Eurocode 3 Design of steel structures, as implemented by its UK National Annexes.
A companion publication, Joints in Steel Construction: Simple Joints to Eurocode 3 (P), covers design of nominally pinned joints. [en] This paper presents a research on a specific type of unstiffened extended end-plate joint used to connect I-shaped beams to concrete-filled rectangular hollow section columns.
The main idea is to use long bolts throughout the column to connect the beam end-plates, so avoiding intermediate connecting elements (e.g.
a reverse U channel) or. contains sections on bolting to hollow structural sections (hss), welding considerations for hss, simple shear connections to hss columns, fully restrained moment connections to hss aisc design guide 24 - hollow structural section 2 / hollow structural section connections / aisc design guide 24 it should also be noted that very large diameter.

The behavior of concrete-filled HSS columns with or without fire protection subjected to axial or eccentric loads was experimentally investigated and the results presented in this paper.
The parametric and experimental studies provide information for the development of formulas for the calculation of the fire resistance and fire protection. Composite HSS — Composite HSS, or concrete-filled tubes (CFT) as it is sometimes referred, is an underutilized form of design and construction that has several advantages.
This presentation gives an introduction into some of the practical considerations to follow during design and construction.

CIDECT promotes structural hollow sections (HSS) usage for good engineering practice and suitable architecture by providing information, contacts, organizing conferences etc.
CIDECT was founded as non-profit association. Until today CIDECT is operated by its members only, granting that almost all funds are used for research topics. With various design standards and recommendations (Eurocode has been ried out multi-planar joints, especially with rectangu- section members by Redwood (), Gidd- ings () and Scola (); much more work has been done joints with circular hollow section by decided that electrode material would be a grade higher in strength equivalent to.Joint Info Resource # e The purpose of this ePipe document is to provide a listing of the different pipe joint types and requirements of the different pipe materials in one location as a reference.
