Meeting Title: 

URM Seismic Resilience Symposium


Portland State University Lincoln Hall




Unreinforced Masonry (URM) buildings present a challenge for earthquake-prone communities. There are over 1,650 URM buildings in Portland and millions around the world. These structures are important historic, architectural, cultural, and economic landmarks, but their vulnerability to earthquakes imperils these buildings and the people in them.

The URM Seismic Resilience Symposium, July 18-20, 2019, is a three-day event for architects, engineers, owners, property managers, and anyone that might deal with URM buildings.

The symposium will include two days of lectures focusing on topics and concerns related to URM buildings, including:

  • Earthquake Background
  • URM Construction and Seismic Engineering Technology Options
  • Building Codes and Historic Preservation Requirements
  • Seismic Upgrade Project Considerations and Costs
  • Public Policy, Finance, and Resiliency

Speakers include prominent engineers and architects from Oregon, Washington, California as well as leading experts from British Columbia, Canada, New Zealand, Portugal, and Italy.

Meeting Title: 

Dynamic Interfaces of Water-Resistive Barriers


Aceh Community Room
Mercy Corps, 45 SW Ankeny St
Portland, OR 97204


Dr. M. Steven Doggett, Ph.D.


Water-Resistive Barriers (WRBs) have evolved to serve compound forms and functions. Despite these advances, performance expectations still reflect over-simplistic assumptions and problematical testing methods. Interfaces with modern wall components also remain ill-defined with respect to the WRB’s primary function of liquid water resistance. Industry trends toward component integration have further strained the WRB’s intended role.

This presentation explores new findings from experimental research and computational modeling to demonstrate performance attributes of recognized WRB systems. Moisture transport and storage are reviewed for three dynamic interfaces: A) the exterior insulation interface; B) the substrate interface; and C) the fastener interface. Directives for industry research, testing standards, and product innovation are discussed.

Dr. Doggett is the Principal Scientist and founder of Built Environments, Inc. an architectural & building science consulting firm specializing in building enclosure design and research. His background includes extensive field experience with complex building enclosure failures, particularly those involving air, heat, and moisture transport. He merges this experience with innovative design practices to assist multi-stakeholders achieve more resilient, higher-performing buildings. Dr. Doggett is actively engaged in enclosure design, assembly and material research, and building simulations involving computational fluid dynamics, 3-D thermal modeling, and hygrothermal modeling. Dr. Doggett is the former chair of the Minnesota Building Enclosure Council.
