Resilient Design & Retrofit

SP3 enables engineers to consider damage and loss reduction directly in the design process, to achieve more resilient buildings.

Advanced Seismic Risk Assessment (PML+)

SP3 provides a consistent and credible method for a seismic risk assessment report. SP3 provides the basic results needed for a PML study, and unique additional building-specific risk information.

SP3 for PML+



SP3 provides high-fidelity building-specific vulnerability curves. These can be used for an owner to negotiate insurance premiums and for an insurance company to better understand building-specific risk.

SP3 is Comprehensive & Credible

SP3 distills years of cutting-edge research to equip engineers to comprehensively assess seismic damage, loss, and building repair time.

SP3 is Fast

SP3 provides a streamlined workflow to give results in hours (rather than days or weeks), with the ability to refine the analysis at any step.

SP3 is Transparent

SP3 is based on the open-source FEMA P-58 methodology, providing unprecedented transparency for the basis of the risk assessment.

SP3 is Building-Specific Risk

SP3 provides building-specific risk information, rather than predictions based on a general class of buildings. Refine your building model to get tailored insights or perform sensitivity studies.

SP3 is Standardized

SP3 provides a standardized analysis method that is consistent and repeatable, being backed by the comprehensive FEMA P-58 component damageability database which is based on the past 30 years of structural engineering research.

Customer Spotlight

SP3 represents a genuine advancement in the set of tools available to structural engineers whose practice includes seismic risk assessment and mitigation.

Saif Hussain, SE, CEO Seismic Structures International

SP3 opens the door for using FEMA P58 to engineers and adds a valuable toolbox to design offices. The input tabs are intuitive and user friendly. The support group is helpful and knowledgeable.

Amir Gilani, PhD, SE Miyamoto International, Inc.

With SP3, the lending and sales industry will get state-of-the art earthquake science and structural performance modeling in a prepopulated, automated, format that is quick and relatively inexpensive for the consulting structural engineer to use.

Eric Von Berg, CMB Newmark Realty Capital, Inc.

The application of FEMA P58 is going to have a transformative impact on the structural engineering profession's ability to communicate with clients and the public. The SP3 software makes the application of FEMA P58 as simple as it could possibly be - I have no hesitation in recommending its use to obtain a USRC Rating.

The SP3 team, in collaboration with CoreBrace, recently completed a Resilient Design Guide for BRBF Buildings. This guide provides recommendations for strength and stiffness design requirements, quantifies the effects of including a back-up frame, addresses how to control residual drifts in design, and also discusses non-structural component considerations during resilient design. The guide is now available from Brandt Saxey, S.E., LEED A.P. at CoreBrace.

In recognition of the contributions and impacts of SP3, the Structural Engineers Association of Northern California (SEAONC) awarded HBRG founders, Curt Haselton and Jack Baker, the 2019 Helmut Krawinkler Award. This award is given each year to honor and acknowledge individuals for outstanding leadership in implementing state-of-the-art research into practice. The award was presented by Ron Hamburger at this year's SEAONC Business Meeting and Award Ceremony held in San Francisco on June 4th. It was great that many key SP3 advisers and pioneering users were able to attend the meeting. Professor Helmut Krawinkler was both a mentor and friend to Jack and Curt, and the team is honored to have received such wonderful recognition for their work.

On May 2nd, the SP3 team and Simpson Strong-Tie® gave a joint webinar regarding seismic risk assessment and the resilient design and performance of steel frame buildings using the Yield-Link ® Connection. The webinar covered the fragilities of the connections themselves, the effects on drift and floor acceleration demands, and how to use FEMA P-58 and SP3 for resilient design of this structural system. The webinar is available here and the slides here.
