Seismic Design Guide for Low-Rise Confined Masonry Buildings

The purpose of these guidelines, prepared by a commettee of international experts led by Roberto Mieli of Mexico and Svetlana Brzev of Canada, is to:

Explain the mechanism of seismic response of confined masonry buildings for in- and out-ofplaneseismic effects and other relevant seismic response issues,
Recommend prescriptive design provisions for low-rise buildings related to the wall layout anddensity, and prescribe minimum size requirements for structural components of confinedmasonry buildings (tie-columns, tie-beams, walls), reinforcement size and detailing, and
Provide a summary of the seismic design provisions for confined masonry buildings fromrelevant international codes.

This document is divided into three chapters. Chapter 1 provides an overview of confined masonryconstruction and its components. It discusses the seismic performance of confined masonrybuildings in past earthquakes, and is based largely on the publication Earthquake-ResistantConfined Masonry Construction (Brzev, 2008). Chapter 2 presents general requirements related toconfined masonry construction. Chapter 3 outlines a guideline for low-rise non-engineered confinedmasonry buildings (up to two stories high). These buildings could be constructed withoutengineered design performed by qualified engineers or architects, and thus no design calculationsor procedures are included. Many single-family dwellings are built in this manner.
This document was developed by a group of international experts in earthquake engineering andconfined masonry construction. The recommendations are based on design and constructionexperience and research studies from countries and regions where confined masonry constructionhas been practiced for many decades, including Mexico, Peru, Chile, Argentina, Iran, Indonesia, China, Algeria and Slovenia. References to relevant provisions of various international standardsand codes have been made in the document.
