Modern building facade design concepts consider all cladding materials, including dimension stone cladding, as nonstructural elements designed to transmit localized gravity and lateral loads to the primary building structural elements. In practice, the structural backup behind dimension stone cladding can take a wide variety of forms, including cast-in-place concrete shear walls, brick and concrete masonry units, aluminum curtain wall system framing, hot and cold rolled steel subframes, and precast concrete panels and members. The flexural stiffness of these backup systems can vary widely, with cast-in-place concrete shear walls on one end of the stiffness spectrum and aluminum curtain framing on the other. The stiffness of dimension stone cladding relative to the backup system can have a significant effect both on the stresses induced in the cladding and the loads transmitted through the cladding anchors. Likewise, the stiffness of the anchor elements and the backup system can affect the loading and stress distribution within the cladding panels. This paper addresses some of the issues associated with the interaction of dimension stone cladding panels, panel anchors, and metal backup structures, and the effects of relative stiffness on load and stress distributions. Information is presented that was obtained from laboratory tests and analyses for new designs, as well as investigations of dimension stone cladding failures.

"Twelve peer-reviewed papers demonstrate the continuing advancement in the understanding of dimension stone used in building construction. Topics cover: Strength Testing--addresses testing to determine strength characteristics of dimension stone cladding panels. Design--covers a wide range of topics, including the advantages and disadvantages of three common dimension stone paving installation techniques; the relationships between stone material strength, anchorage strength, and induced stress states for four common dimension stone cladding anchorage configurations; and more. Evaluation and Investigation--provides observations regarding investigations into the causes of dimension stone cladding deterioration and failure. Durability--discusses the complex issue of dimension stone durability using three different approaches; a large-scale European research project to investigate the causes of marble and limestone cladding panel bowing, develop preconstruction testing parameters to assess bowing potential, and assess proposed remedial efforts to reduce or inhibit ongoing bowing; and more."--Publisher's website.

One of the most important aspects of designing dimension stone cladding involves determining the configuration, size, and spacing of the anchorages that will affix the stone panels to the underlying building substrate. Information from many sources, including material strength testing, anchorage strength testing, and knowledge of the stress states created within stone cladding panels by loaded anchorages, is crucial to this process. In this paper, relationships are examined between material strength, anchorage strength, and induced stress states for four common anchorage configurations: edge dowels, Type 31 back anchors, and edge kerfs with strap and split-tail anchors. For each of these four anchor types, the relevant material and anchorage strength test data obtained for a medium-grained granite, in conjunction with finite element computer analyses of the stress states induced in the stone panels by the anchors and within the material strength test specimens, are presented. Material strength test configurations evaluated include ASTM C 880 Standard Test Method for Flexural Strength of Dimension Stone, ASTM C 99 Standard Test Method for Modulus of Rupture of Dimension Stone, and a proposed test for punching shear currently under consideration by ASTM Subcommittee C18.01. All anchorage strength tests were performed in accordance with ASTM C 1354 Standard Test Method for Strength of Individual Stone Anchorages in Dimension Stone.

This volume presents new methodologies for the design of dimension stone based on the concepts of structural design while preserving the excellence of stonemasonry practice in façade engineering. Straightforward formulae are provided for computing action on cladding, with special emphasis on the effect of seismic forces, including an extensive general methodology applied to non-structural elements. Based on the Load and Resistance Factor Design Format (LRDF), minimum slab thickness formulae are presented that take into consideration stress concentrations analysis based on the Finite Element Method (FEM) for the most commonly used modern anchorage systems. Calculation examples allow designers to solve several anchorage engineering problems in a detailed and objective manner, underlining the key parameters. The design of the anchorage metal parts, either in stainless steel or aluminum, is also presented.

"This guide presents design principles that require consideration when designing anchorages and evaluating exterior stone to be compatible with its proposed use. It is an overview of current techniques and a review of minimum requirements for sound stone engineering and construction. The guide does not list all possible methods of attachment nor does it provide a step-by-step procedure for stone anchor engineering"--Page 1.
