Book Description
PCI 150-23 Standard For Design of Precast Insulated Wall PanelsThis standard provides minimum requirements for the design of prestressed or nonprestressed precast insulated wall panels. Included within are provisions for composite action, wythe connectors, reinforcement, strength evaluation, service-level analysis, earthquake resistance, and temperature effects, among others. This standard was developed through the ANSI-accredited consensus process.

Book Description
During the mid-20th century, with the rise of industrial prefabrication, precast concrete sandwich panels started being used as cladding for buildings. Since then, society and construction industry have become increasingly aware of energy efficiency in all fields, including affordability and sustainability consciousness, while maintaining the buildings’ durability. As such, buildings have been subject to increasingly stringent requirements which has kept the technology of sandwich panels continually at the forefront of building envelope evolution. Nowadays, sandwich panels have reached the highest standards of functional performance and aesthetic appeal. In building construction, these sandwich panel attributes combine with the well-known advantages of prefabrication including structural efficiency, flexibility in use, speed of construction, quality consciousness, durability, and sustainability. Sandwich panels have gained more exposure, thus representing quite a significant application within the prefabrication industry and a vital component of the precast market. The fib Commission “Prefabrication” is eager to promote the development of all precast structural concrete products and to share the knowledge and experience gained, to aid with practical design and construction. By issuing this comprehensive overview, “Guide to Good Practice”, a better understanding of design considerations, structural analysis, building physics, use of materials, manufacturing methods, equipment usage and field performance will be provided. This document contains the latest information currently available worldwide. The Commission is particularly proud that this document is a result of close cooperation with PCI and that it is published by both the fib and PCI. This cooperation started six years ago, first with comparing the different approaches to several issues, then progressively integrating and producing common documents, like this one, that hasn’t yet been treated in a specific Guide by either body. This Guide is intended to be the reference document to all who are interested in utilising the advantages of Precast Sandwich wall panels. In conjunction with the previously published Planning and Design Handbook on Precast Building Structures, the designer will have significant resources to integrate sandwich wall panels into any applicable structure.

Book Description
This report addresses many of the design issues that designers will face with respect to thin-wall precast concrete panels as the U.S. Army Corps of Engineers continues with its innovative approach to construction of navigation structures using lift-in, float-in, and in-the-wet construction methods. The report focuses on the issues of concrete panel design that relate to the special considerations associated with the innovative methods currently being used by the Corps. This report is intended to supplement guidance criteria currently available in Engineer Manuals and Engineer Technical Letters, as well as the industry standards such as the American Concrete Institute's building code and the American Association of State Highway and Transportation Officials' Bridge Code. Special consideration is given to the applicability of thin-wall precast panels, the materials used in their construction, and constructibility issues associated with them. Other topics that are addressed include loads to consider during precast operations, considerations with regard to connection of precast items, issues associated with in-fill concrete, and requirements and guidelines regarding construction details. Several chapters of the report are devoted to issues that are directly related to design, such as serviceability requirements, strength requirements, flexural design, shear and torsion design, and fatigue strength design. Finally, information is presented on design with respect to composite construction and loading combinations that should be considered for thin-wall panels.

Book Description
Insulated concrete form (ICF) walls are used in low- to mid- rise construction and are cost-competitive with wood and masonry walls. In addition, these wall systems meet increasingly strict insulation requirements in building codes and therefore have the potential to be more cost-effective than wood construction. There is one drawback, however, and that is that their minimum reinforcing requirements are determined by ACI 318-19, including maximum spacing limits and minimum reinforcement ratios. These reinforcement requirements exceed what is required to meet strength demands. As such, there is a need to investigate the required spacing and amount of reinforcement. In addition, there is an interest in using steel fibers to replace some of the wall reinforcement. Previous studies have not investigated these design parameters. This research project utilized non-linear finite element modeling (FEM) to investigate the impact of reducing minimum steel requirements as well as the use of steel fiber in planar walls. The FEM was based on prior work and validated using in-plane and out-of-plane tests. The wall models were subjected to monotonically increasing shear in the out-of-plane direction and a constant, distributed axial load at the top of the wall. The reference wall geometry was selected to meet a single bay of a one-story structure as well as future test specimens. Using the validated modeling approach and reference geometry, a parametric study was conducted to investigate the impact of the following design parameters on the structural response of the wall: (1) bar spacing, (2) number of curtains of steel, as well as (3) steel fiber dosage in conjunction with the first two variables. The research findings are as follows: (1) the peak strength of the wall is determined by the tensile capacity of the plain or fiber-reinforced concrete (FRC), (2) the bar spacing and the number of curtains of steel only impact the residual strength increase after cracking, and (3) it appears possible to use FRC with starter bars for some walls as this concrete provides shear, moment and axial capacity and the starter bars transfers the forces to the foundation. The findings suggest more economical bar layouts for ICF walls are possible without compromising the structural response.
