The International Code Council (ICC) and the Structural Engineers Association of California (SEAOC) have partnered to release a joint publication of the 2018 IBC SEAOC Structural/Seismic Design Manuals. The updated series provides a guided approach to applying the structural provisions of the 2018 International Building Code (IBC) and referenced standards.

This updated, four-volume series includes:

  • Volume 1: Code Application Examples – Volume 1 contains code application examples based on the IBC and ASCE 7-16, including determination of seismic irregularities, combinations of structural systems, determination of drift, support of discontinuous systems and analysis of seismic forces applied to equipment, nonstructural elements and nonbuilding structures.
  • Volume 2: Examples for Light-Frame, Tilt-up and Masonry Buildings – Volume 2 contains code application examples of light-frame, tilt-up and masonry construction. Diaphragm flexibility, center of mass, collectors and chords, deflection and anchorage are discussed through examples. In- and out-of-plane seismic loads are analyzed.
  • Volume 3: Examples for Concrete Buildings – Volume 3 contains code application examples of concrete construction. Moment frames, braced frames and shear wall construction are analyzed.
  • Volume 4: Examples for Steel-Framed Buildings – Volume 4 details sample structures with steel moment frames or braced frames and steel connections.

“Providing resources that aid the career development of building industry professionals is key to our efforts to welcome the next generation of industry leaders,” says ICC executive vice president Mark Johnson. “This collection is an excellent reference and study guide for the NCEES Structural Exam. Each volume of the Structural/Seismic Design Manual collection serves as an invaluable resource for civil and structural engineers, architects, academics and students.”

“We are excited for the release of the 2018 Structural/Seismic Design Manuals and the guidance they will provide to structural engineers,” says Katy Briggs, SEAOC project co-manager. “In addition to updates to previously published design examples, new design examples have been added throughout the four manuals to address structural engineering challenges.”

“This new edition will provide much-need guidance on numerous topics, including new seismic design provisions in the latest International Building Code, ASCE 7, and material standards,” adds SEAOC president Rafael Sabelli. “This will be an important resource for engineers working to learn and apply those requirements.”

The 2018 IBC SEAOC Structural/Seismic Design Manuals are available for purchase through the Code Council store individually or as a collection in both print and a new eBook format to use on any device.



  1. The design example in Volume 3 for a post-tensioned concrete beam which is “not designated as part of the seismic-force-resisting-system” (ACI 318-14 & 19 Section 18.14) contains numerous glaring errors, Code violations, and departures from standard practices, and if enforced by Building Officials it will set back post-tensioned construction by 50 years.

  2. Thank you for sharing about international code council and seaoc release new seismic design manuals, these will be really helpful for me. I love reading this blog; it talks so much about planning a great idea about it. Keep sharing such informative articles in future, will be appreciated.I have also found this resource useful and its related to what you are mentioning.
