Overview of the Seismic Design Process Based on ASCE/SEI 7-22
Credits: 2 PDH
PDH Course Description:
This practical 2-PDH course provides an organized overview of the seismic design process for new buildings based on ASCE/SEI 7-22, together with the fundamental structural-dynamics principles that support seismic analysis and design.
The course begins by explaining the principal stages of the seismic design process, including determination of the Risk Category, seismic hazard level, and Seismic Design Category; selection of the seismic force-resisting system; preliminary structural design; seismic analysis; verification of strength and stiffness; system-specific detailing; and anchorage and bracing of nonstructural components.
Participants are also introduced to important specialized topics that may influence seismic design, including performance-based seismic design, tsunami-resistant design, soil–structure interaction, energy dissipation systems, seismic isolation, and the seismic design of nonbuilding structures.
The structural-dynamics portion of the course explains the response of a single-degree-of-freedom system to earthquake ground motion. Topics include mass, stiffness, natural period, damping, inertia forces, equations of motion, response spectra, elastic and nonlinear response, period lengthening, hysteretic energy dissipation, and the role of the response modification coefficient, R.
By completing this course, participants will develop a clearer understanding of how seismic design criteria, structural-system selection, dynamic response, and specialized earthquake-resistant technologies fit within the overall seismic design process established by ASCE/SEI 7-22.
