SUMMARY:Cross-Laminated Timber (CLT) Shear Walls and Resilience-Based Design
DESCRIPTION:Cross Laminated Timber (CLT) Shear Wall Design Example\nSeismic 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. \nLearning Objectives: Participant will: \n\nLearn about the CLT shear wall design example appearing in the 2020 NEHRP Provisions: Design Examples\nLearn about seismic design coefficients and the associated height limits for the CLT shear wall system appearing in ASCE/SEI Standard 7-22\nBe introduced to design requirements for CLT shear walls appearing in SDPWS-21 Appendix B\nGain awareness of application of CLT shear wall requirements for shear strength\, overturing\, and deflection\n\nResilience-Based Design and the NEHRP Provisions\nThis 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. \n\nUnderstand resilience and functional recovery as they relate to earthquake design and to each other.\nUnderstand the elements of a functional recovery objective.\nUnderstand the precedents for resilience-based design embedded in current building codes and standards.\nUnderstand how the elements of current earthquake design might be adjusted to achieve a functional recovery objective
