Evolution of Seismic Design Values over the Years The 2020 NEHRP Provisions, and ASCE 7-24 that is based on it, adopt a new USGS ground motion model that incorporates stie class and basin effects directly into the calculation of gridded seismic design values. For the first time, these values are available only through an on-line […]
The 2020 NEHRP Provisions developed major updates to nonstructural seismic design provisions which were then adapted for Chapter 13 of ASCE/SEI 7-22. The primary focus of the updates is the equation used to determine design forces for nonstructural components, but there are updates to other provisions as well. The training will be given in two parts. Part […]

Coupled shear wall systems are recognized as distinct from isolated shear wall systems in Canadian and New Zealand codes; they are also accorded higher response modification factors in view of their superior seismic performance. ASCE 7 has so far made no such distinction. A ductile coupled wall system of reinforced concrete has now been defined […]
The 2020 NEHRP Provisions and ASCE/SEI 7-22 incorporate several notable changes to seismic design of diaphragms. This includes expanded applicability of the ASCE 7-16 Section 12.10.3 alternative design provisions for diaphragms, originally developed in the 2015 NEHRP Provisions. This also includes new Section 12.10.4, codifying the rigid wall-flexible diaphragm (RWFD) methodology published in FEMA P-1026, Seismic Design of […]

Designing a structure to resist earthquakes requires several considerations that can be ignored in design to resist most other loads. The loading is more severe, the permissible response will usually include damage to the structure, as well as the systems and components supported by the structure, and the levels of uncertainty in loading and response […]
The 2020 NEHRP Recommended Provisions: Design Examples illustrate and explain the applications of the 2020 NEHRP Recommended Seismic Provisions and the associated changes in the seismic provisions of ASCE/SEI 7-22, Minimum Design Loads for Buildings and Other Structures. This virtual training session provides a discussion of the following items: An overview of the NEHRP Provisions intent and purpose, and the relationship of […]
During our networking session at Building Innovation 2021, many leaders spoke about being their authentic self. How much of yourself can you really share with others at work? For example, if you’re kindhearted, does this come through, or do you pretend to be someone else at work for appearances sake? Does your wardrobe reflect your […]
Mentorship has been key for the career growth of many women in the C-suite in the built environment. It’s important to find a quality mentor and be a mentor for those who need guidance. You’re invited to this limited-invitation virtual event with keynote speaker, Judy Dinelle, CGP, CAPS, AMA and building ambassador with 84 Lumber […]
The built environment is being challenged by many trends and disruptors: digital transformation, off-site manufacturing, sustainability concerns, an aging workforce leading to lack of skilled labor, as well as COVID-19, which is affecting the health, safety, and well-being of workers. Organizations must remain resilient to meet challenges and continue to grow and flourish. To become […]
Women in the built environment are trailblazers. Many times, they were the only woman in their department, on the leadership team, or the first woman to lead their organization. While you may not have been the first woman, everyone has a unique story to tell. “Being the only” means that everyone has a narrative about […]
