Description: The new prescriptive design standard for exterior concrete walls for one- and two-family dwellings applies to the design and construction of concrete footings, foundation walls, and above-grade concrete walls built with insulating concrete forms or removable formwork. Ideal for residential architects, designers, and contractors interested in building homes combining cast-in-place wall systems with light-frame interior construction. Features diagrams and expanded design tables to simplify the engineering requirements for homes up to two stories plus a basement.
Improvements from earlier Prescriptive Method for Insulating Concrete Forms in Residential Construction, Second Edition (EB118):
General:
Publication now covers both insulating concrete forms and removable formwork
Covers Seismic Design Categories A, B, C, D0, D1, D2 with limitations
Foundation Wall Tables:
Expanded to provide design solution for a maximum backfill height equal to the maximum supported wall height
Expanded design solutions for 6-in waffle and screen grid ICFs
Above Grade Wall Tables:
Now based on use of Grade 60 steel with adjustments given for use of Grade 40
Flat wall tables expanded to include designs for 8-in and 10-in nominal walls
Expanded tabulated solutions for 4-in flat walls and 6-in waffle and screen grid walls
New table provides design solution for above grade walls constructed continuous with stem-wall where slab-on-ground does not provide lateral support
New tables entered directly with the basic wind speed and exposure category which saves one step over design procedure in early edition
Lintel Tables:
Provides solutions for both Grade 40 and Grade 60 steel
Several bar size and number of bar combinations now available
Solid Walls for Resistance to Lateral Forces Tables
Revised tables for one-story, first story of two-story, and top story of two-story, for wind perpendicular to ridge, and for same conditions with wind parallel to ridge
New tables entered directly with the basic wind speed and exposure category which saves one step over design procedure in early edition
Connections between concrete walls and light-framed floors and roofs:
Updated to comply with new anchorage to concrete provisions of ACI 318-02 and AF&PA National Design Specification (NDS) for Wood Construction
Connection loads based on ASCE 7-05
Now includes new cold-formed steel framing floor and roof connection details
The first standard developed by the Portland Cement Association using an ANSI accredited process.
