Masonry Designers’ Guide, 6th Edition

Section was for the Strength Design of Masonry. Recent research compared eight different design methodologies, used, or recommended for use, around the world, with the results of laboratory testing. The masonry modulus of rupture is used for the design of unreinforced masonry. Please allow extra time for your msc to be processed. 208 shear capacity of such members was reduced to promote a ductile failure mode. The MSJC harmonized the modulus of rupture between the various design methods.

Protected Download Single User. In the past, shear analysis in ASD of reinforced masonry has been treated very differently than in SD. The MDG-6 is an excellent resource for masonry designers as well as students learning about masonry for the first time because it: The edition of the Code and Specification reformatted the material into five chapters.

In ASD, the shear stress on an element was calculated and compared to a lower level allowable stress which could be resisted by the masonry alone. Because of these inconsistencies, ASD will still be slightly more conservative in almost all cases.

In ArticlesCodes and Standards Comments 0. Description Additional information Description The best guide on designing masonry is now even better! With the availability of robust SD provisions, which have been substantiated by many laboratory test programs, the MSJC continued the harmonization process by reviewing these research results and by performing numerous trial designs comparing the results of the reinforcement requirements of elements designed by both the ASD and the SD procedures.


The major harmonization effort in the MSJC was to change the design equations for anchor msjx, so that a designer would get approximately the same bolt spacing using either the ASD procedures or the SD procedures. Mshc website uses cookies to ensure you get the best experience on our website. This allowed them to include a SD chapter for masonry in the MSJC, so that they could begin shaping a workable set of strength design provisions.

This is msc recognition of the wide variety of winter construction site conditions possible, and the fact that technology, mxjc and methods of construction advance rapidly. Topics covered in the MDG-6 include masonry materials, testing, quality assurance, quality control, construction methods, structural design, seismic design, and using the MSJC with model Building Codes.

About The Masonry Society Formed inThe Masonry Society TMS is an educational, scientific, and technical society dedicated to the advancement of scientific, engineering, architectural, and construction knowledge of masonry.

The requirements are grouped within temperature ranges, and while the provisions are prescriptive in nature, there is also considerable latitude given to the contractor to use individual methods to satisfy the code requirements.

The main masonry 20008 in use today are brick, concrete masonry and glass block masonry. The trial designs indicated a very poor correlation between the flexural capacity of elements designed using SD and the same element designed using ASD and the 0.

The MDG-6 is an excellent resource for masonry designers as well as students learning about masonry for the first time because it:. Named for Professor Paul Haller, the Haller Award recognizes an individual engineer or engineering firm that has enhanced the knowledge of masonry in practice. No reduction of the shear capacity of such members is required.


The MDG has become one of the most popular design guides for masonry due to its extensive examples and practical coverage of masonry design issues. Long squat elements are typically shear dominated, but generally have excess shear capacity.

Based on this research, the MSJC modified the SD methodology for shear capacity and converted it to an ASD methodology for shear stress, based on the jsjc in both the masonry and the reinforcement. Hybrid Masonry Construction February 16, The allowable steel reinforcement stress for flexure, direct tension and shear has been increased to 32 ksi.

These three organizations formed the Masonry Standards Joint Committee. The companion CD included with the book includes additional resources including the complete MDG-5 for reference, Excel spreadsheets used in some of the design examples, additional examples based on IBC requirements, and select technical notes on clay brick and concrete masonry that are often used by designers. This research concluded that, of the eight methodologies, the TMS SD for shear was the best predictor of shear capacity and that the TMS ASD for shear in reinforced masonry was the worst predictor of shear capacity.

The Society is a not-for-profit, membership driven organization that gathers, correlates, and disseminates information for the improvement of the design, construction, manufacture, use, and maintenance of masonry products and structures.

Formed inThe Masonry Society TMS is mzjc educational, scientific, and technical society dedicated to the advancement of scientific, engineering, architectural, and construction knowledge of masonry. Masonry design and construction produces architecturally award-winning structures which are safe and durable. The process ksjc harmonization of design provisions in the MSJC documents dates back to the edition of the Code and Specification.
