Low-Rise Residential Construction - Details

These details were developed by the Light Gauge Steel Engineers Association (LGSEA) for the North American Steel Framing Alliance (NASFA). They are intended to provide designers and contractors with guidance on design, detailing, and construction of low-rise residential buildings that utilize cold-formed steel framing members. Details contained in this document were selected based on their cost effectiveness at the time of this publication. Efforts have been made to present accurate, reliable, and useful information. The connections between members are shown as screw connections; other types of connections such as welds, bolts, powder-actuated fasteners, clinches, or pneumatically driven fasteners are acceptable. Although it is common for cold-formed steel framing members to have web “punchouts” for passing bracing or utilities, punchouts are shown in some details only. Punchouts are acceptable and vary in size, configuration, and spacing depending on the manufacturer and/or design.

BS 6954-1: 1988 Tolerances for building — Part 1: Recommendations for basic principles for evaluation and specification

This International Standard describes the nature of dimensional variability in building and the purposes for which it has to be quantified, and defines the factors to be taken into account in the evaluation, specification and verification of tolerances for the manufacture of building components and for site work. It applies to components and buildings generally, including those designed in accordance with the principles of modular co-ordination.

This International Standard describes the fundamental characteristics of dimensional variability in building and of the particular case of combination of random unrelated variables; it sets out the need to relate dimensional variability to the limits imposed on joint widths by the need for satisfactory functioning.

This part of ISO 3443 provides a basis for relating joint clearances and target sizes and for the prediction of fit within the context of dimensional coordination, including modular coordination.

Handbook of Steel Drainage and Highway Construction Products

INTRODUCTION
Years of dependable service and a multitude of wide ranging installations have led the corrugated steel industry to play a major role in modern engineering technology for drainage systems. Flexible steel conduits play an important role in the form of culverts, storm sewers, subdrains, spillways, underpasses, conveyor conduits, service tunnels, detention chambers and recharge systems; for highways, railways, airports, municipalities, recreation areas, industrial parks, flood and conservation projects, water pollution abatement and many other programs.

This is the Second Canadian Edition of the “Handbook of Steel Drainage and Highway Construction Products”. It has been developed and published by the Corrugated Steel Pipe Institute, representing the CSP industry in Canada. The First Canadian Edition of this book was written and published by the American Iron and Steel Institute in 1984. Since then there have been a number of reprints, but no major changes. This second edition is the result of a thorough review, revision and updating of information to reflect the current state-of-the-art and needs of the users in Canada.
Some of the specific changes that have been made include:
• The addition of spiral rib CSP and deep corrugated structural plate profiles.
• Structural design in accordance with the 2001 Canadian Highway Bridge Design Code CSA-S6 for structures 3 m in span and larger.
• Design examples illustrating the structural design methodology.
• Additional retaining wall types.
• All metric information.
