Using FRP and FRCM for Structural Retrofit Applications Told Through Case Studies and Innovative Testing
Wednesday, January 13, 2021
Simpson Strong-Tie looks forward to presenting an educational-based webinar on the use of composite strengthening systems, namely Fiber Reinforced Polymers (FRP) and Fabric Reinforced Cementitious Matric (FRCM), for the structural retrofit of existing building structures. This webinar includes:
1) A case study that covers the innovative use of FRP on an existing structure to meet project-specific requirements. We are excited to team up with Marc Stryer, S.E., principal at Tipping Structural Engineers, to present on the use of FRP to seismically strengthen a five story concrete building. An experimentally-backed solution showed that FRP can be used to increase the shear strength and ductility of a rectangular concrete column where retrofit access was limited to three sides only.
2) A case study that highlights using FRP creatively alongside traditional retrofit approaches to provide the best overall solution for strengthening an existing building’s lateral system. This project resulted in the development of new Shear Transfer Bracket to transfer shear forces from existing concrete to new concrete elements.
3) The use of FRP anchors to improve shear wall and joint (slab to wall) connection performance.
4) The importance of including field testing requirements in the project specifications to address FRP anchor quality control.
5) A case study that highlights the application of FRCM used to strengthen existing masonry walls for improved earthquake load resistance.
6) An experimentally-backed approach for strengthening damaged wood piles using a pile splice repair technique that uses FRP.
Composite Strengthening Systems
Mr. Aniket Borwankar is a Composite Strengthening Systems (FRP & FRCM) Development Manager with Simpson Strong-Tie. Mr. Borwankar received his Master’s degree in Civil Engineering from Vanderbilt University with a focus on carbon fiber reinforced cement based materials. After working for eight years as a consulting engineering at firms in Tennessee and California, where he was involved with design of new building and retrofit of existing structures, Mr. Borwankar joined Simpson Strong-Tie in March 2017. Since then, he has been involved in designing FRP projects and educating engineering firms on the design principles of FRP. His wide range of experience includes working with engineering firms on seismic retrofit of non-ductile concrete buildings in California using composite strengthening systems. In addition, he is involved in research and development of new FRP products and FRP applications for Simpson Strong-Tie, and works with consulting engineering firms to design projects and test new FRP applications for job specific field conditions. He was also involved with conception, testing and development of Shear Transfer Bracket, a new FRP element to transfer forces between new and existing concrete elements.

Tipping Structural Engineers
As a Principal at Tipping, Marc directs his vision, talents, and energies externally and internally: He works to understand and internalize the unique goals, concerns, and needs of his clients. He manages internal operations to allow for superior client service and, in alignment with client goals, pursues innovative avenues for project delivery and design collaboration. Internally, Marc has committed to developing the next generation of leaders; and he works to nurture, create, and shape a workplace that inspires its creative, passionate members to engage in their best work.
Marc’s wide range of experience includes work for engineering, architecture, and construction firms. Since joining Tipping in 2005, he has combined his engineering and management expertise on projects involving both new and existing structures, with an emphasis on sustainable design and seismic safety. His significant contributions to recent Tipping projects include Campbell Hall, a six-story concrete Astrophysics Department building for UC Berkeley; Minnesota Student and Trainee Housing, two new six-story concrete residential buildings for UCSF; a new office building for the Commonwealth Club in San Francisco, and the nine-story 2001 Market Street mixed-use development in San Francisco, for which he served as lead engineer.
One of Marc’s first projects at Tipping was the multiple- award-winning seismic retrofit of 2850 Telegraph Avenue in Berkeley; he also co-authored articles in Concrete International and the Post-Tensioning Institute Journal on Tipping’s pioneering breakthrough using vertically post-tensioned concrete walls for seismic resistance, first applied to that project. Other Tipping projects in which he played a key role include Barneys NY, the Living Building-certified Omega Center for Sustainable Living, and Pixar Animation Studios.
Marc earned his AB in molecular biology from Princeton University and MEng in civil engineering from the Massachusetts Institute of Technology. After nine years at Tipping, he was named principal in 2014.
