Builders’ Guide to Residential Steel Floors

The Builders Guide to Residential Steel Floors is provided as a guideline to facilitate the appropriate use of cold-formed steel floor framing in the construction of conventional one- and two-family residential dwellings, townhouses, and multifamily dwellings. The provisions in this document were developed by applying accepted engineering practices, test results of steel floor assemblies, and other published reports, technical bulletins, and manufacturer data. However, users of this document should verify its compliance with local code requirements and seek any necessary regulatory approvals prior to use. The user is advised to refer to applicable building code requirements for technical issues beyond the scope of this document and when engineered design is called out. The first three chapters of this document provide an overview of cold-formed steel framing, including its advantages, technical resources, tools and fasteners, and material properties. The overview has many helpful tips and guidance, particularly for first timers. Builders and contractors must understand the strengths and weaknesses of the material they are using. They must also know how to cut, trim, measure, mark, and install steel framing members. Steel framers must know how to order steel members, how to select the proper tools, and how to fasten framing members together. While many of these considerations are best learned by practice, the transition between wood and steel floor framing can be rather easy with the proper guidance and planning.
Chapters 4 and 5 of this document describe how to construct cold-formed steel floors and related sub-trade installations. Chapter 6 provides general recommendations and construction guidelines that are gathered from experienced steel framers. The intent of that chapter is to provide steel framers with good practices that could save them time, material, and frustration.

Moisture-Resistant Homes, A Best Practice Guide and Plan Review Tool for Builders and Designers With a Supplemental Guide for Homeowners

This tool was developed with the following important end-users in mind: designers, builders, remodelers, and homeowners. The scope of the document is focused on relatively common moisture issues encountered in one- and two-family dwellings (attached and detached). The featured best practices are intended to address these issues in typical light-frame wood construction using common building systems. The practices deal with direct moisture issues as well as related design concerns that also influence moisture management in a house. Many of the best practices will provide multiple layers of protection against moisture (e.g., roof overhangs + window flashing), which is an intentional approach to providing good long-term performance. Also, given the diversity of housing materials and construction styles in the U.S., the general approach within the guide is to present moisture management ideas that can lead to several viable solutions, rather than specifying a single workable solution that assumes the use of a limited selection of materials and details. In sections where a single detail is provided, additional details or variations may also provide workable solutions. This approach gives designers and builders the flexibility to develop tailored solutions that reflect their material choices, design preferences, and strategies for meeting various code requirements.

Internal Curing: A 2010 State-of-the-Art Review

The American Concrete Institute in 2010 defined internal curing as “supplying water throughout a freshly placed cementitious mixture using reservoirs, via pre-wetted lightweight aggregates, that readily release water as needed for hydration or to replace moisture lost through evaporation or self-desiccation” (American Concrete Institute, 2010). While internal curing has been inadvertently included in many lightweight concretes produced within the past 100 years, it is only within the first decade of the 21st century that this technology has been intentionally incorporated into concrete mixtures at the proportioning stage, using a variety of materials including pre-wetted lightweight aggregates, pre-wetted crushed returned concrete fines, superabsorbent polymers, and pre-wetted wood fibers. This report provides a state-of-the-art review of the subject of internal curing, first addressing its history and theory, and then proceeding to summarize published guidance on implementing internal curing in practice and published research on its influence on the performance properties of concrete. The ongoing exploration of extensions of the internal curing concept that employ the internal reservoirs to contain materials other than water are reviewed. Finally, the critical issue of sustainability is addressed. An extensive internal curing bibliography that is also available over the Internet is included in an appendix. The report is mainly focused on the utilization of pre-wetted lightweight aggregates as the internal reservoirs due to this being the current established practice within the U.S.
