- Summary:
- The Masonry Society committee in charge of the publication Building Code Requirements for Masonry Structures, TMS 402, rewrote the chapter containing provisions for masonry veneer in the 2022 edition. One change incorporated in this new chapter was an engineered method for anchored veneer design. A key design criterion of the engineered design method is that the designer know the veneer tie stiffness and strength. However, there is no standard method for testing veneer ties that captures these properties. This paper proposes a conceptual standard for veneer tie testing. In this proposed test method, the measured ultimate load of the tie is based on the peak strength, or the load at a defined deformation. The nominal tie strength is then related to the 75th percent confidence level of the 5th-percentile value using a lognormal distribution. The stiffness is determined as a secant stiffness between two load levels. For adjustable ties, the test configuration is important, as both the strength and stiffness can vary significantly depending on the configuration. A procedure to determine a single representative strength and stiffness for design is presented, with these quantities being representative of the average tie strength for various configurations, and with an ultimate strength being limited to 1.5 times the strength determined at the configuration that results in the lowest nominal strength
