CON3001: Transverse Slotted Holes Design Bearing Strengthlogin to downloadConnections27-Oct-09Kevin Cowie
No distinction is made in the Steel Structures Standard NZS 3404 (SNZ, 2007) between the design ply bearing capacity for a long slotted hole in which the slot is perpendicular to the direction of the bearing load and a standard ...
CTG1006: Steel Corrosion Rates in Water and Soillogin to downloadCoatings20-Oct-09Kevin Cowie
Guidance on typical corrosion steel rates in water and soil for design use is provided in the recently published NZS3404.1 Steel Structures Standard - Materials, Fabrication, and Construction (SNZ,2009). The design rates given are those to be used for ...
CON1001: Moment End Plate - Column Sidelogin to downloadConnections26-Aug-09Kevin Cowie
Standard moment end plate connections (MEP) have been developed by Steel Construction New Zealand Inc. The design procedures are presented in Structural Steelwork Connections Guide: Design Procedures, SCNZ 14- 1:2007 (Hyland et al, 2008). The connection details are given in table form ...
CON1002: CHS Collar Jointslogin to downloadConnections26-Aug-09Kevin Cowie
This article presents a method for designing the collar joints of a moment connection between an I section beam and a circular hollow section (CHS) column. The procedure is developed principally for the semi-rigid flange bolted joint (FBJ). However the principles can ...
CON1101: Semi-Rigid Sliding Hinge Jointlogin to downloadConnections26-Aug-09Kevin Cowie
The Sliding Hinge Joint (SHJ) is a new semi-rigid joint system developed for moment resisting steel frames. It has the ability to remain rigid under in-service conditions or ultimate state wind loading, and to rotate under severe earthquake loadings, returning to the ...
MAT1005: Properties and Assessment of Historical Structural Steelworklogin to downloadMaterials03-Jul-09Kevin Cowie
The refurbishment or ‘adaptive re-use’ of existing buildings currently forms a significant part of the workload for many architects and engineers. The structural engineer will be required to make an appraisal of the existing steelwork in these buildings. ...
GEN3001: Maximum Spacing of Thermal Movement Jointslogin to downloadGeneral03-Jul-09Kevin Cowie
Although buildings are often constructed using flexible materials, roof and structural expansion joints are required when plan dimensions are large. The maximum distance between expansion joints is dependent upon many variables, including ambient temperature during construction and the expected ...
ERC1004: Sleeved Holding Down Boltslogin to downloadErection & Construction29-Jun-09Kevin Cowie
One of the greatest problems faced by a steel erector on site is inaccuracy in the locations of the anchor bolts. Precision surveying equipment and techniques are required to accurately set out solidly cast-in anchor bolts in accordance with ...
