MEM6301: Design of Angle Trusseslogin to downloadMember Design26-Aug-11Alistair Fussell
Angle sections are commonly used as members in light weight triangulated structures such as trusses and towers. The attraction of angle section is their ease of fabrication, they are however more complex to design than other types of structural sections. ...
FIR003: Fire Resistance of Composite Beams with Profiled Steel Deckinglogin to downloadFire23-Aug-11Kevin Cowie
When a composite beam is constructed using a profiled steel deck, a void is created between the deck and the top flange of the beam. With open trapezoidal steel decks this void is comparatively large while with a ‘closed ...
CON1303: Heavy Brace Gusset Design Examplelogin to downloadConnections27-Jul-11Kevin Cowie; Alistair Fussell
This worked example illustrates the ductile design of brace/beam/column gusset plate connection. The example is based on the design approach presented in Steel Advisor CON1301. ...
CON1301: Heavy Brace Gusset Plate Connections for Braced Steel Frameslogin to downloadConnections20-Jul-11Alistair Fussell
Heavy brace gusset connections for the purposes of this paper are defined as gusset plates that connect large tubes (circular and square) or buckling restrained braces used in braced frames (concentric and eccentric) for medium and high rise applications. This ...
ERC1005: Loads on Newly-Finished Composite Floorslogin to downloadErection & Construction20-Jul-11Stephen Hicks
This article is written in response to frequently asked questions regarding the performance of composite floors soon after concreting. This Steel Advisor article clarifies the basis for some of the requirements given in national and international good practice guides, and ...
CON1302: Light Brace Cleat Connections for Braced Steel frameslogin to downloadConnections25-May-11Alistair Fussell
Light bracing cleat connections are defined as unstiffened cleats that connect light bracing such as flat bars, rods or small tubes sections (round or square) to beams or columns (figure 1). These types of bracing systems are typically used in ...
MAT1006: Steel Plate Availability in New Zealandlogin to downloadMaterials21-Dec-10Kevin Cowie
Bridge construction is a demanding application typically requiring plate welded sections. Material optimisation for welded plate sections involves a careful matching of strength requirements with available plate sizes to minimise waste and welding requirements and to reduce transportation costs. This ...
WRL1001: Withdrawal of Welder Qualification Standard NZS 4711login to downloadWelding26-Sep-10Alistair Fussell; Clark Hyland; Charles Clifton
Some changes to the way NZ welders qualify for structural welding will result from the Standards NZ announcement in March 2010 that NZS 4711 is to be withdrawn. With effect from 1 April 2011, new or renewal welder qualifications will ...
CTG1007: Galvanic/Dissimilar Metal Corrosionlogin to downloadCoatings20-Sep-10Kevin Cowie
Galvanic corrosion is the additional corrosion that occurs when dissimilar metals are in contact in the presence of an electrolyte. The corrosion of a metal, the anode, results from the positive current flowing from the anode to the ...
ANA5201: Design Example - Analysis and Design of Jib Crane Boomlogin to downloadStructural Analysis14-Jul-10Charles Clifton; Kevin Cowie
This article provides an example of how to design the boom of a jib crane to NZS 3404 (SNZ, 2007). This example illustrates the use of second order and restraint requirements of NZS 3404. ...
