Concrete Masonry Units
Materials and Manufacturing of Concrete Masonry Units Concrete masonry units are formed from zero-slump concrete, sometimes using lightweight aggregate. The concrete […]
Masonry Structural design
This book was developed from a set of masonry course notes used for many years in a semester-long, undergraduate and graduate course in masonry engineering at The University of Texas at Austin. It covers the design of masonry structures using the 2009 International Building Code, the 2008 Masonry Standards Joint Committee Code and Specification, and other documents referenced by those standards. The book is intended for an undergraduate or a graduate course in masonry as part of a civil engineering or architectural engineering curriculum. It can also be used for self-study and continuing education by practicing engineers. It emphasizes the strength design of masonry, and also includes allowable-stress design.

Classification of Masonry Elements
Masonry elements can be designed in at least two ways: According to their structural function According to the approach used
Classification of Masonry Elements by Structural Function
Nonload-bearing masonry: Supports vertical loads from selfweight only, plus possibly loads from out-of-plane wind or earthquake. Load-bearing masonry: Supports vertical loads from
