Masonry Design Manual

The Masonry Design Manual, 4th Edition, assists non-engineers designing for or working with masonry in understanding masonry materials and the construction process. It references provisions of the 2006 International Building Code, ACI 530/ASCE 5/TMS402, and the 2005 Specification for Masonry Structures, and includes unit conversions and hundreds of masonry details.

Masonry Design Manual, 4th Edition, is published by Masonry Institute of America and the International Code Council. This new edition assists the designer in understanding masonry materials and the construction process. It incorporates the latest information available and is consistent with the provisions of the 2006 International Building Code, ACI 530/ASCE 5/TMS402, and the 2005 Specification for Masonry Structures. The book covers clay brick, concrete masonry, natural stone, terra cotta, glass block, reinforcing steel, veneer, mortar and grout, brick masonry construction. It includes unit conversions as well as hundreds of masonry details.

A valuable tool for the non-engineer designing for or working with masonry.

Masonry is perhaps the oldest building material, yet it is the least understood. This book is intended to assist the designer in understanding the materials and the construction process. It is our desire to fulfill a need of the designer, that is, to understand masonry materials in simple terms.

This book incorporates the latest information available and is consistent with the design provisions of the 2006 International Building Code, the 2005 Building Code Requirements for Masonry Structures (ACI 530/ASCE 5/TMS 402) and the 2005 Specification for Masonry Structures (ACI 530.1/ASCE 6/TMS 602). The authors are presenting the material intended for the benefit of non-engineering disciplines, such as architects and contractors. There are a number of engineering concepts contained in the publication, but they are important to understanding the value of the basic concepts of masonry.

There are several sources that this publication incorporates, including the previous editions of the Masonry Design Manual, Technical Notes from the Brick Industry Association and National Concrete Masonry Association and a number of other technical publications developed by the Masonry Institute of America and other sources were used in the development of this publication. The compilation of this information is focused to the benefit of the designer and should be a valuable tool in improving the masonry industry.

This publication is not intended to replace the designer and anyone developing a masonry project should seek the assistance of a design professional, The Masonry Institute of America welcomes recommendations for the extension and improvement of the material and any new design techniques that may be incorporated into future editions.

DESIGN OF STRUCTURAL CONNECTIONS TO EUROCODE 3 FREQUENTLY ASKED QUESTIONS

The purpose of this publication is to document each of these questions together with their answers. To facilitate easy of use this document is split into the following Chapters:
Chapter 1 - Introduction
Chapter 2 - Bolts
Chapter 3 - Welding
Chapter 4 - Structural Modelling
Chapter 5 - Simple Connections
Chapter 6 - Moment Connections
Chapter 7 - Column Bases

Each chapter starts with a brief over-view of the method use in prEN1993-1-8. This is followed by the commonly asked questions together with their answers. In due course the information contained within this document will be put on the Internet and will form part of an easily accessible Internet course for the design, fabrication and erection of structural steelwork connections.

Concrete Model Building Subtypes Recommended for Use in Collecting Inventory Data

This study was conducted by the National Institute of Building Sciences’ Building Seismic Safety Council (BSSC). The goal was to develop standardized categories for older concrete buildings that incorporate more detail than those included in the standard set of Federal Emergency Management Agency (FEMA) Concrete Model Building Types – namely, C1-frames, C2-shear walls, C3-concrete frames with masonry infill, and PC2-precast frames. The recommended “subtypes” generally can be identified without extensive engineering evaluation and therefore can document the inventory of older concrete buildings in an effort to better quantify how many structures might require mitigation. The identification of these subtypes also contributes to determination of the highest priority research needed to enable rapid implementation of performance-based seismic design for mitigation.
For initial collection of inventory data, building age, height, and occupancy should be documented. Data on additional attributes that affect risk of high damage levels or collapse would require engineering evaluation and cannot be collected reliably using typical inventory-collection techniques; however, additional attributes that may be important for identifying a high-risk concrete building are discussed.
The primary attribute suggested for initial classification is occupancy and 13 different occupancies are recommended. The structural systems typically, but not exclusively, used for each occupancy are described as are potential seismic deficiencies. Also described are the many variations that can affect the risk levels of each of the FEMA Concrete Model Building Types (C1, C2, C3, and PC2) including strength, stiffness, configuration irregularities, and gravity frame type. These descriptions are organized into Structural Type Families based on the four primary model building types.
Without further understanding of the collapse mechanisms of older concrete buildings, building subtypes that can reliably distinguish seismic risk levels cannot be established
