The Impact on Lifelines & Access to Internet

Join NIBS for the third installment of our Infrastructure 2022 webinar series as we discuss lifelines, closing the digital divide, and clean energy as outlined in the IIJA.

SEISMIC DESIGN OF COUPLED COMPOSITE PLATE SHEAR WALLS / CONCRETE FILLED (C-PSW/CF)

Composite Plate Shear Wall / Concrete Filled (C-PSW/CF), also known as the SpeedCore system, is an efficient seismic force-resisting system for buildings. Two types of C-PSW/CF systems are possible: coupled and uncoupled. Seismic design requirements for uncoupled C-PSW/CF systems were addressed in ASCE/SEI 7-16 and AISC 341-16, Section H7. Coupled C-PSW/CF systems are more ductile and have more redundancy than uncoupled systems, but ASCE/SEI 7-16 did not assign seismic design factors in Table 12.2-1. A FEMA P695 study was conducted to verify the design factors that should be used for such Coupled C-PSW/CF structures. Adding this as a separate category in Table 12.2-1 was important because they can be used as the elevator core wall systems in modern high-rise buildings. Two line items featuring this system are now added to ASCE/SEI 7-22 Table 12.2-1 under Building Frame Systems and Dual Systems with Special Moment Frames. R = 8, Cd = 5.5, and Ω0 = 2.5 are the design factors in both line items. The height limits are the same as for corresponding uncoupled isolated wall systems. A definition for the Coupled C-PSW/SF system and its design and detailing requirements were not included in AISC 360-16 or AISC 341-16. A new Section H8 in AISC 341-22 includes specific provisions for the definition and use of this Coupled C-PSW/CF system, including details on the capacity design principle limits on applicability. This presentation outlines the above developments and presents a detailed design example illustrating the Coupled-C-PSW/CF seismic force-resisting system.

Cross-Laminated Timber (CLT) Shear Walls

Seismic force resisting systems based on Cross Laminated Timber (CLT) shear walls have garnered considerable attention for use in building structures around the world for many years with standardization as a seismic force resisting system happening in the U.S. for the first time with inclusion of seismic design requirements in 2021 Special Design Provisions for Wind and Seismic (SDPWS) and in ASCE 7-22 Minimum Design Loads and Associated Criteria for Buildings and Other Structures. This presentation summarizes the CLT shear wall design example contained in the 2020 NEHRP Provisions: Design Examples, provides background on the new system, and illustrates application of the CLT shear wall system design requirements through a design example. Resilience-Based Design and the NEHRP Provisions This talk presents the new concepts of resilience and functional recovery as they relate to earthquake design. Referencing Resource Paper 1 of the 2020 NEHRP Provisions, it looks ahead to how building codes and design standards might begin to incorporate functional recovery time as an explicit measure of performance and basis for design. The ideas are illustrated by hypothetical application to the CLT Shear Wall design example.

DIAPHRAGM SEISMIC DESIGN PART 2

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 Rigid Wall-Flexible Diaphragm Buildings: An Alternative Method. These diaphragm design provisions have been largely driven by new research, including testing and numerical studies. They have been developed to better reflect diaphragm dynamic response and deformation capacity, and to provide improved performance, in some cases with reduced construction cost. This material will be presented in two webinars. The first webinar will provide a general introduction to seismic design of diaphragms and then focus on design examples implementing Section 12.10.3 provisions. The second webinar will repeat the general introduction and then focus on design examples implementing new Section 12.10.4 alternative RWFD provisions.

Transportation Infrastructure: Your Daily Commute

The passage of H.R.3684 – the Infrastructure Investment and Jobs Act – ensures daily commutes across metropolitan cities and small towns will be improved. The bill reauthorizes surface transportation programs for five years and invests $110 billion in additional funding. The bill also guarantees $89.9 billion for public transit over the next five years between reauthorizations and new funding. Highways and bridges will be repaired, intersections redesigned, designated bus lanes created, bicycle lanes protected, and commuter rail services expanded. Join us as our expert panel discusses the fundamentals of upcoming infrastructure projects and how they will affect our daily lives and commutes.

FUNDAMENTALS OF EARTHQUAKE ENGINEERING

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 are greater than for ordinary loads. This webinar includes an overview of earthquake ground shaking, dynamic response to ground shaking, and the influence of yielding within the structure on the response. These issues underlie the NEHRP Recommended Provisions and a good understanding of the concepts are an important first step in successful implementation of a design complying with the Provisions.

Introduction to the 2020 NEHRP Recommended Seismic Provisions: Design Examples

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 the Provisions to the seismic provisions of ASCE/SEI 7-22 A summary of notable earthquakes in history and how they impacted seismic design The history and role of the NEHRP Provisions in advancing seismic design Highlights of major updates in the NEHRP Provisions and seismic provisions of ASCE/SEI 7-22 An introduction to the organization and content in the new Design Examples

Resilience 2021: The Shift from Relief and Response to Hazard Mitigation

Mitigation is the sustained action that reduces or eliminates long-term risk to people and property from natural hazards and their effects. Over the last decade, the United States has seen a shift in emergency management from relief and response to reducing hazard risk. Key points in this effort are building resilient communities and creating community-based disaster management plans. According to the National Oceanic and Atmospheric Administration (2020), the nation has averaged 14 floods, wildfires, and other disasters every year for the last five years. These disasters annually cost America $106 billion. The NIBS 2019 Natural Hazard Mitigation Saves Report has found that adopting the latest building code requirements is affordable and saves $11 per $1 invested. Furthermore, the study found that federal grants save $6 per $1 cost. Since 1995, public-sector investment in mitigation by the Federal Emergency Management Agency, U.S. Economic Development Administration, and U.S. Department of Housing and Urban Development cost the country $27 billion but will ultimately save $160 billion, meaning $6 saved for every dollar invested. Join our esteemed panel as they discuss the importance of hazard mitigation in the United States.

Resilience 2021 Webinar Series: Building Resilience through BIM

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 resilient, we must respond and adopt new ways of thinking and working. Building information modeling (BIM) can help address the climate, urbanization, performance and skills shortage challenges, alongside the implementation of many best practice approaches. Organizations that seize this opportunity will be able to compete successfully in global markets.

Resilience 21: The Importance of Seismic Functional Recovery and Community Resilience in the Built Environment

Nearly half of the U.S. population (150 million people) reside in portions of 42 states that are at risk of experiencing a damaging earthquake within the next 50 years. That’s according to the NIST-FEMA Special Publication Recommended Options for Improving the Built Environment for Post-Earthquake Reoccupancy and Functional Recovery Time. In regions of high seismic risk, where an earthquake hasn’t occurred for some time, scenario studies predict deaths in the thousands, injuries in the tens of thousands, and hundreds of billions of dollars in direct economic losses, along with long-term, destabilizing impacts to community function. Our nation’s seismic risk is largely mitigated through earthquake-resistant buildings, which are regulated by model building codes. Federal policy now calls for improving functional recovery of the built environment to increase earthquake resilience at the community level. Functional recovery design represents a significant shift from the current safety-based practice for the building design and construction industry.

The Case for Resiliency in the Wildland-Urban Interface

As of July 22, the National Wildland Fire Preparedness Level sits at a 5 – it’s highest level. This means that the majority of firefighting resources are committed, due to the large amount of wildland fire activity throughout the country. From Alaska to Wyoming, thousands have been forced to evacuate. Historically, wildfires are most likely to occur between May and October. However, with warmer and drier climate conditions, the risk of wildfire will continue to threaten our communities and their built environment year-round for the foreseeable future. According to the National Interagency Fire Center, more than 2.2 million acres already have burned in the U.S. this year. That is about 500,000 more acres than this time in 2020, when a total of 10.1 million acres burned. This devastating loss makes it imperative that disaster resiliency be on the forefront of the recovery efforts.
