Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This study investigates two aspects of precast concrete insulated sandwich wall panels, namely mechanical connections and fatigue behaviour. In the first part, flexural tests were performed on panels with various end support conditions, loading orientations, and reinforcement and shear connector materials. Bolted angle connections were used to simulate practical support conditions, while loads were applied in a manner to simulate windward pressure as well as suction. Panels with steel and basalt fibre-reinforced polymer (BFRP) longitudinal reinforcement were tested and compared. Discrete steel and BFRP shear connectors were also used and evaluated. The bolted angle connections provided partial end fixity, thereby increasing the overall strength and stiffness relative to identical panels simply supported by rollers during testing. In all cases the bolted connections succeeded in developing the full strength of the sandwich panels. Panels with steel reinforcement failed due to rupturing of flexural reinforcement, while a panel with BFRP reinforcement failed due to rupturing of shear connectors and crushing of concrete in one wythe. Panels loaded in the direction of wind pressure achieved higher peak loads than identical panels loaded to simulate suction. An analytical model accounting for material nonlinearity, end support conditions and partial composite action from the shear transfer system was developed. The model accurately predicted flexural stiffness, while the peak load was underestimated in most cases. In the second part of the study, seven fatigue tests were performed on four panels with either steel or BFRP flexural reinforcement and shear connectors. Cyclic bending was conducted at two loading amplitudes: a high (Pdef) and a low (Pstr) load, representing serviceability limits for deflection and stress, respectively; both considerably higher than the maximum national wind load. The effect of a moderate axial load, as in loadbearing walls, was examined. The panels initially had a Degree of Composite Action (DCA) of 76-84%. The axially-loaded steel-reinforced panel achieved 1M cycles under Pstr, then another 1M under Pdef. Its DCA reduced to 73 then 65%. Without axial load, 1M and 0.24M cycles were achieved under Pstr and Pdef, and DCA reduced to 69 and 22%, respectively. The BFRP-panel failed at 0.07M cycles at Pstr. Its DCA reduced from 76 to 69%. It was then axially loaded and retested successfully to 1M cycles. Stiffness degradations of 12-50% consistent with DCA reductions were observed.

This book was released on 2015 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2000 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "To ensure sufficient composite action to meet structural strength and stiffness requirements in precast concrete sandwich wall panels, the designer must provide adequate shear transfer between concrete wythes. In a typical sandwich panel, shear transfer may be provided through several different mechanisms. These mechanisms include: (1) solid concrete regions; (2) mechanical connectors that pass through the insulation wythe; and, (3) bond between the concrete wythes and the insulation. The objective to the work presented in this report is to investigate the flexural behavior of sandwich panels and the contribution to composite action provided by regions of solid concrete, wythe connectors, and bond. Tests were performed on four full-scale precast sandwich wall panels. A Prototype panel was tested, which included regions of solid concrete in the insulation wythe, metal wythe connectors, and no attempt was made to disrupt the bond between the concrete wythes and the insulation wythe. The degree of composite action developed by each of the different shear transfer mechanisms was then evaluated by testing three additional panels that included only one mechanism of shear transfer (solid concrete, wythe connectors, or bond). It was found that, for the panel geometries and materials treated in this study, the solid concrete regions provide most of the strength and stiffness that contribute to composite behavior. Steel M-tie connectors and bond between the insulation and concrete contribute relatively little to composite behavior. Therefore, for design purposes, it is recommended that solid concrete regions be proportioned to provide all of the required composite action in a precast sandwich wall panel. A precast concrete sandwich wall panel constructed similarly to the Prototype panel treated in this study will behave as a fully composite panel in terms of service load-deflection behavior and flexural strength."

Available in PDF, EPUB and Kindle. Book excerpt: Sandwich panels are being used increasingly as the cladding of buildings like factories, warehouses, cold stores and retail sheds. This is because they are light in weight, thermally efficient, aesthetically attractive and can be easily handled and erected. However, to date, an authoritative book on the subject was lacking. This new reference work aims to fill that gap. The designer, specifier and manufacturer of sandwich panels all require a great deal of information on a wide range of subjects. This book was written by a group of European experts under the editorship of a UK specialist in lightweight construction. It provides guidance on: * materials used in manufacture * thermal efficiency and air- and water-tightness * acoustic performance * performance in fire * durability * special problems of sandwich panels in cold stores and chill rooms * architectural and aesthetic considerations * structural design at the ultimate and serviceability limit states * additional structural considerations including fastenings, the effect of openings and the use of sandwich panels as load-bearing walls * test procedures The book concludes with some numerical design examples and is highly illustrated throughout.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal efficiency of Precast Concrete Sandwich Panel Walls has become a major topic when discussing the building envelope in academia. At Utah State University, research is being done to evaluate the structural and thermal efficiency of fiber reinforced polymer connectors being used today. In evaluating several different proprietary fiber reinforced polymer systems, researchers plan to develop design procedures to help engineers accurately determine minimum design requirements when using fiber reinforced polymer connectors. This largely requires a determination of the degree of composite action incurred by each system. Testing is performed by constructing small scale specimens (3 ft. by 4 ft., 0.91 m by 1.22 m). Each specimen contains one of the fiber reinforced polymer connecting systems. By constructing a five-wythe, two wall specimen, direct shear can be applied to the connectors using a push-off shear test method. By performing this test it can be determined to what degree the panel is acting compositely. Once the degree of composite action is determined, correlation can be made between design and degree of composite action. Economizing and simplifying this procedure is key to further implementation of precast concrete sandwich panel walls in all areas of our building infrastructure.

This book was released on 2021 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insulated concrete sandwich wall panels provide structurally and thermally efficient building envelopes and are becoming more popular as energy regulations tighten. To continually adapt to an ever-changing building market and new energy regulations, insulated concrete wall panels are being constructed with thinner wythes, thicker insulation, and relying on partial composite action to decrease material costs and increase thermal and structural efficiency. Numerous methods of the design of partially composite insulated concrete sandwich wall panels have been introduced in recent decades and have been verified by comparing their results to existing experimental testing. Existing testing data for insulated concrete sandwich wall panels does not contain adequate experimental testing for thin wythe and thick insulation sandwich wall panels; therefore, the current methods of design have not been adequately verified for the design of such sandwich wall panels. This project aimed to validate current methods of design of sandwich wall panels for the use of thin wythe and thick insulation concrete sandwich wall panels. The study concluded that current methods of design adequately predict behavior of thin wythe and thick insulation concrete sandwich wall panels within the elastic region but do not adequately predict the ultimate capacity of thin wythe and thick insulation concrete sandwich wall panels. The predictions of two existing methods, which predict elastic shear stiffness of connectors, were compared to the results of 15 double shear tests for three unique connectors with agreeable results. The predictions of three methods, which predict elastic behavior and two methods, which calculate ultimate capacity, were compared to the testing results of six full-scale panels. All methods predicting elastic behavior proved to be accurate and one method adequately predicted ultimate panel capacities.
