Functional Resilience

The United States continues to see a rise in losses due to damage from natural disasters. What is important to note is that there has been a significant increase in losses starting in the 1970s. The losses presented here and throughout this article unless otherwise noted are from the Property Casualty Service and presented in 2010 equivalent dollars.

At the same time the US is experiencing these greater losses, the building and design industry has taken a greater interest and earnestly looked at how to build structures that are more sustainable -- especial in terms of the construction process and materials. Recently, a new layer of interest has been added to understanding what sustainable design and construction means.

The Portland Cement Association has recommended adding measures into the building codes, and adding the idea of functional resilience to the way U.S. structures are designed.

Functional resilience incorporates many aspects of building design and construction, and while a very broad concept, designs that include provisions for functional resilience will tend to be more durable, robust, disaster resistant, have longer life expectancies, and be more readily adapted for reuse and even re-purposing. “Integration of durability and functional resilience into sustainability codes, standards and programs is long overdue,” David Shepherd, director of sustainability for the Portland Cement Association (PCA) said. “Some say the most sustainable structure is the one that isn’t built. We believe the most sustainable building is the one still standing.”

Being built to withstand natural disasters is one idea of functional resilience. For example, looking at how we design structures to withstand wind events, such as a midwestern tornado, shows how much we might be saving.

Here are the combined losses reported for tornados, hail storms, and thunderstorms. Increases in the frequency and severity of other events are not clearly evident as shown with National Oceanic and Atmospheric Administration data on tornados. The number of severe tornados is not increasing, but decreasing…

The dramatic increase in losses is also shown to be more rapidly increasing that the amount of residential construction according to the U.S. Census Bureau statistics. The same is true for commercial construction put in place. Annual and cumulative commercial construction have consistent slopes as compared to the slope of losses.

Chart 2

If the relationship is not directly related to increased frequency of events, re-distribution of population, or the amount of buildings built, what else can be a significant factor.

There have been significant changes in construction practices in the United States since the 1970s. Each of these alone may not have had a significant effect, but each warrants consideration with regard to its role in increased losses.

A resilient building is not limited to one that is operational after a natural disaster, but also one that can withstand the hardship of the passing years. The Brookings Institution projects that by 2030, the U.S. will have demolished and replaced 82 billion square feet of its current building stock, or nearly one-third of existing buildings, largely because the vast majority of them weren’t designed and built to last any longer. Robust, functionally resilient buildings are frequently reused and even re-purposed when downtowns are renovated.

Danbury

Hospital Parking Expansion Crisis Solved with Precast!
Resolving parking issues is the first phase of the huge expansion planned for the Danbury Hospital in Danbury, CT. The expansion includes adding a fourth level (207 spaces) to the existing Blue Garage, and an addition to the West End Garage (98 spaces). However the new level to the Blue Garage could not commence until the existing structure (built in the 1980’s) was brought up to current seismic code. The Design-Assist approach used for this project brings together the Engineer of Record, Desman Associates, CT; the precaster, Blakeslee Prestress, CT; the Architect, S/L/A/M Collaborative, CT; and the contractor, Gilbane Building Company, CT, early in the process.

Thomas Basile, R/A, at Desman Associates, utilizes this approach because it “speeds up the process and timeline of construction, and any details for the project concerning the precast can be worked out between the precaster and engineer early on so that the most economical and efficient production methods are used for the project.” This approach aided in resolving the challenge of bringing the existing Blue Garage up to seismic code.

PCI & Sika Announces 2012 Big Beam Contest/Begins August 15

Big Beam

PCI has announced competition guidelines for the 2011-12 Big Beam Contest. Each student team must work with a PCI Producer Member to build a precast-prestressed concrete beam which is 18 ft. long and tested as a 16 foot span. The beams will be tested and prizes awarded for best performance in the stated areas. Students must discuss both the structural design and the concrete mix design for the beam. Note: The loading pattern is changed for 2011-12.

The contest begins August 15, 2011 and ends June 15, 2012. All beams must be fabricated and tested within this time frame. Results are due by June 15, 2012 at PCI Headquarters.

Thanks to Sika for sponsoring the PCI Big Beam Contest.
