Book Description
Precast insulated concrete sandwich panels have been used with proven success in commercial building application as wall elements to provide both vertical and lateral strength and thermal and environmental protection. Various configurations and materials have been used to provide certain degrees of strength, thermal resistance and composite action. The mechanics of the sandwich panel rely on the transfer of compressive and tensile forces due to flexure via shear through the web connectors. These web connectors have varied from steel wire trusses to carbon fiber composite grid trusses to solid concrete zones. For optimum thermal performance the connectors not providing a thermal bridge are best suited. For optimum strength and stiffness performance the shear connectors that create the highest degree of composite action and anchorage in the concrete zones shall be used. Furthermore, if the insulated concrete sandwich panels can be better understood, developed and tested in the horizontal application rather than as a wall element, they can be used for roof and possibly floor applications. This will provide environment and thermal resistance and required strength and stiffness. This study investigates the design and testing of several scaled test sandwich panel configurations using solid web FRP plate shear connectors. The stiffness, strength and degree of composite action for each set of panels is calculated and compared and finally 2 full scale test panels are developed and tested. Along with testing and calculations, numerical modeling or finite element analysis is employed to show correlation between the test results for future development of an analytical model. Precast concrete sandwich panel engineering performance varying depending on the degree of composite action of its constituent materials and strength of properties. Employing a nonlinear numerical solver that can capture the quasi-static response of the panels under flexural loading is valuable and desirable for future development. These test panels, both scaled and full-scale show adequate results for strength, stiffness and degree of composite action to justify further development and research into their use as roof or floor structural support members. Long term creep effects have also been investigated in this study, however further creep studies are warranted and recommended. Finally, these panels are not limited to the use of residential and commercial application, rather they have the potential as suitable candidates for structures intended to provide blast and/or accidental explosion protection.

Book Description
This book presents articles from The Australasian Conference on the Mechanics of Structures and Materials (ACMSM25 held in Brisbane, December 2018), celebrating the 50th anniversary of the conference. First held in Sydney in 1967, it is one of the longest running conferences of its kind, taking place every 2–3 years in Australia or New Zealand. Bringing together international experts and leaders to disseminate recent research findings in the fields of structural mechanics, civil engineering and materials, it offers a forum for participants from around the world to review, discuss and present the latest developments in the broad discipline of mechanics and materials in civil engineering.

Book Description
Finite element analysis techniques are developed for the solution of nonlinear problems involving sandwich composite materials. Each layer of a sandwich panel is represented explicitly so that multicore panels and other configurations are easily considered. The finite element discretization is performed using arbitrary-shaped, fully compatible shell and continuum elements, as well as special elements representing full-depth and/or face sheet stiffeners. Each of these elements is capable of representing arbitrarily large displacements and rotations, since no simplifying assumptions are made in the theoretical formulation. Elastic-plastic effects may also be considered. An associated computer program is described which may be used to perform linear or nonlinear solutions for mechanical and thermal loading, linear natural frequency calculations. Several example problems are solved to demonstrate the capabilities of the program. (Author).

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.
