Jack Baker and Curt Haselton have worked together for over a decade on research to support and advance our structural engineering profession.
These activities have included fundamental research projects, technology transfer projects with the Applied Technology Council (including ATC-58), and consulting projects to utilize research tools in the real world.
Through this work, we observed that advanced design and assessment methods are often difficult to implement in practice. This difficulty often arises because research calculations and software cannot keep up with the rapid pace of work in a design office. Given our experience in performance-based engineering research and software development, we saw a chance to address this problem.
We created the Haselton Baker Risk Group in 2014 to produce software that meets the needs of cutting-edge engineering design professionals and enables engineers to quickly implement advanced design and assessment methods into their practice. When equipped with the tools to comprehensively assess performance of buildings, we believe that engineers will be able to design more resilient projects and communities.

Structure Magazine published an article by Mr. Ronald Hamburger and Haselton Baker Risk Group Founders Dr. Curt Haselton and Dr. Jack Baker. This article, “Resilient Design and Risk Assessment using FEMA P-58 Analysis”, presents the FEMA P-58 Method, highlights some of the recent updates to the Method, and presents case studies detailing how the Method is being used now to design resilient buildings. You can read the article here.
Dr. Haselton participated in the California Earthquake Authority Research Forum “Innovation in Earthquake Risk Assessment: How Technology is Changing the Industry.” Specifically Dr. Haselton sat as a panel member for the “Role and Practical Application of Technology in Assessing Expected Performance of Houses”; he shared how SP3 can be used in the assessment of wood light-frame buildings and the new SP3 Building-Specific Risk Model. You can find the presentation for the CEA Forum here.
Dr. Haselton and the HB Risk team presented a “White Paper on Expected Seismic Performance of New Building-Code-Compliant Buildings in California.” This paper contrasts the performance of code-compliant buildings at different locations in California showing that new buildings in California are safe but disposable. This paper also contrasts code-compliant building performance with resiliently designed buildings. You can view the white paper here.
In the 5th and final installment in our webinar series Dr. Haselton and Edward Almeter presented a webinar looking in more detail at risk assessment of buckling-restrained braced-frame (BRBF) buildings. This webinar summarized the research and the new SP3 technologies stemming from this project, which now enable more advance assessment and resilient design of BRBF buildings. This technology has just been released and is not yet in the online SP3 system, so if you have a BRBF project and you want to leverage this new technology now, please contact the SP3 team and we would be happy to work with you on your project. You can watch the webinar here or view the slides from the webinar here.
In the 4th installment in our webinar series, Dr. Debock and Dustin Cook presented a webinar on SP3 Building-Specific Risk Assessment for wood light-frame, this work included additions to the SP3 Structural Response Prediction Engine, the SP3 Structural Design and Models Databases, and the SP3 Dynamic Structural Properties Engine. We are excited that risk assessment for this important and prevalent building type is now enabled in the SP3 Building-Specific Risk Model; this has already been implemented into the online version of SP3, and we have been excited to see this new WLF risk assessment method already being used by SP3 clients on their projects. You can watch the webinar here or view the slides from the webinar here.
Continuing our webinar series, on November 14th Haselton Baker Risk Group together with Dr. Koliou and Prof. Lawson presented a webinar on the SP3 Building-Specific Risk Assessment for Tilt-up Buildings. This webinar discusses building-specific tilt-up risk evaluation within the SP3 Building-Specific Risk Model, including additions to the SP3 Structural Response Prediction Engine, the SP3 Fragility Database, the SP3 Building Code Design Database, and the SP3 Dynamic Structural Properties Engine. You can watch the webinar here or view the slides from the webinar here.
This Fall Dr. Haselton gave a two part lecture at the University of California, Berkeley. In the first lecture Dr. Haselton taught on the FEMA P-58 Methodology and in the second lecture he dove into resilient design and the new HBRG Structural Response Prediction Engine. The slides for the first lecture are available here and the second lecture here.
With the recent release of the SP3 Building-Specific Risk Model, clients can now run SP3 analyses using more minimal insurance-level input information, and also use the same Risk Model to complete a higher-fidelity assessment when additional building information or an engineering evaluation is available. To support this process, we are now offering the SP3_Batch service. The SP3_Batch service pairs the SP3 Building-Specific Risk Model with the advanced cloud computing of Amazon Web Services, in order to enable large inventories of buildings to be analyzed quickly. See the release noted for SP3_Batch here.
HB-Risk hosted an online webinar on the new SP3 Building-Specific Risk Model. This webinar discussed the technical basis and various components of the Model, and summarize the detailed R&D involved in developing the Model. With this new SP3 Building-Specific Risk Model technology, clients can now run efficient risk assessments for large inventories of buildings, and use the same underlying technology to complete a higher-fidelity risk assessment when additional building information or an engineering evaluation is available. The presentation is available here and the full webinar video is available here.
Together with a group of leaders in seismic resilience, Dr. Haselton prepared a paper for The Structural Engineers Association of California (SEAOC) 2017 Convention. The paper, “Considerations for a Framework of Resilient Structural Design for Earthquakes”, is available here.
The SP3 team welcomes a new engineering researcher, Edward Almeter. Edward joins the team from the Masters in Earthquake Engineering and Engineering Seismology program in Pavia, Italy and had previously graduated with Honors from State University of New York at Buffalo. Edward's master's research focused on seismic evaluation of steel special concentrically braced frames. On the HB-Risk team, he is currently focused on nonlinear dynamic structural modeling and programming to advance the SP3 performance prediction algorithms.
HB-Risk hosted an online webinar on the new SP3 Structural Response Prediction Engine (SRPE). This new Response Engine enables creation of building-specific vulnerability curves, for most buildings, without needing to create a nonlinear structural model. This new Engine, coupled with other recent developments by the SP3 team, enables many insurance and portfolio types of analysis that were not previously possible. The presentation is available here and the full webinar video is available here.
Earlier this summer, Dr. Haselton co-presented with Dr. Greg Deierlein (Stanford University) at the Spring Seminar for the Structural Engineering Association of Northern California (SEAONC). This presentation was given at the HOK office in San Francisco and focused on “Guidelines for Nonlinear Structural Analysis and Design of Buildings.” This presentation was based on the recent ATC-114 project report funded by NIST. The slides are available here.
HB-Risk welcomes two summer interns. Samantha Grey joins the team for the summer, taking a summer break in the middle of her Master's degree at University of Colorado Boulder. Marisol Alvarez joins the team during her undergraduate work at CSU Chico. Both will be focused on work to further extend our SP3 databases used for seismic risk evaluation.
This webinar covered advanced design methods for modern steel and reinforced concrete frame buildings. Topics include both advanced design methods and new guidelines for nonlinear modeling. For nonlinear modeling, the results of the recent ATC-114 project were presented, entitled Guidelines for Nonlinear Structural Analysis for Building Design (and which currently covers both steel and reinforced concrete frame buildings). Additionally, advanced design methods were discussed, including performance-based design (where advanced modeling is done to demonstrate adequate safety) and resilience-based design (which also uses advanced analytical methods, but where the focused is to design to limit damage, repair cost, and repair time, in addition to ensuring structural safety). The slides for this presentation are available here.
The Los Angeles Mayor’s Office has launched a new effort called Building Forward LA, which is focused on the future of building construction in LA. Dr. Haselton had the privilege of working with Matt Barnard (Degenkolb) and Jeff Ellis (SEAOSC and Simpson Strong-Tie) to present and lead a break-out discussion session on resilient seismic design of new buildings.
HB Risk performed a study benchmarking FEMA P-58 to other building seismic risk assessment methods. This study found that on average FEMA P-58 gave similar results to that of older methods such as the TZ-method or ST-Risk, but was able to capture building specific parameters and provide more in depth building specific results. For more information please read the report.
Founder and CEO, Curt Haselton, gave a presentation on resilience based design and risk management using FEMA P-58 at the SEAOC Seismology Committee. See the presentation here.
HB-Risk performed a study on resilient design metrics calibrated from FEMA P-58. In this study, prescriptive and non-prescriptive design methods were explored and analyzed using the FEMA P-58 method in order to provide observations and recommendations for resilient design. The study has been summarized and reported in the following white paper.
