Adventures in Seismic Risk Mitigation
Speaker: Dr. Troy Morgan
The modern era of civilization is marked by immense networks of complicated, interdependent systems and rapidly evolving technologies, including the world of civil infrastructure. Many of these technologies, while born from academia, are implemented and refined in the world of industry. As today’s complex ideas are put into practice, there is an increasing tendency for things to fail under extreme loading such as earthquakes, and an urgent desire to prevent such failures.

Seismic Design with Viscous Dampers: Applications and Design Strategies
Speaker: Aaron Malatesta
Structural engineers have been using Taylor Devices’ viscous dampers to protect new and existing building structures from seismic excitation for over 25 years. There are a number of different types of damping applications and the primary objective of this presentation will be to demonstrate the basic principles for supplemental viscous damping and how they can be applied on any project. The presentation will include an overview of preliminary design concepts, simplified design procedures, viscous damper modelling, as well as post-processing of results.

Examination of Drift Compatible Nonstructural Wall and Stair Detailing in the NHERI Tall Wood Project
Speaker: Professor Keri L. Ryan
To advance the wood products market, new design solutions for tall wood buildings using mass timber products are being developed. In particular, post-tensioned rocking walls built with cross-laminated timber (CLT) or other mass timber products have been proposed as a seismic resilient lateral system. To advance the seismically resilient mass timber solutions for tall buildings, a comprehensive shake table test of a 10-story building with CLT rocking walls is planned for 2022 on the NHERI@UC San Diego outdoor shaking table.
25
Overview of UCSD EERI Student Chapter and Other Graduate Student Clubs
Speaker: UCSD EERI Student Chapter
Graduate Students will provide an overview of the EERI UCSD Student Chapter and student organizations. The EERI UCSD Graduate Student Chapter aims to work side by side with the regional professional chapter to promote earthquake safety awareness among students. We can plan to host quarterly seminars by inviting outside professionals from industry and academia or take part in seminars organized by the local engineering community.

Seismic Ground Motions for Seismically Isolated Structures and Structures with Damping Systems
Speaker: Dr. Jorge Meneses
One of the seismic analysis and design procedures of seismically isolated structures and structures with damping includes the performance of dynamic time-history analysis of the structure. This procedure requires the development of different input motions or seismic ground motions that will be applied to the structure. The current ASCE 7-16 seismic provisions provide the guidance for developing these seismic ground motions.

Response of Seismically Isolated Structures Subjected to Beyond Design Basis Shaking
Speaker: Professor Gilberto Mosqueda
Seismic isolation has been proven as an effective strategy to protect critical facilities from the damaging effects of horizontal earthquake ground shaking. The increased flexibility and resulting elongation of the natural vibration period of the structure leads to significant reductions in acceleration and forces transmitted to the structure above the isolation level at the expense of large lateral displacements in the isolation system. These large lateral displacements need to be accommodated by the isolation bearings while sustaining the weight of the structure above.
7
Additively Manufactured Composites: Mechanics, Materials, and Manufacturing
Speaker: Professor Mehran Tehrani, University of Texas - Austin
Polymer additive manufacturing (AM) is mostly relegated to the space of rapid prototyping. New approaches for transitioning polymer AM to the production of end-use parts will be discussed and their processing-structure-failure relationships will be elucidated. Carbon fiber has been identified as a potential solution to overcome polymer AM shortcomings, where it improves polymer properties, reduces the time required to manufacture functional parts, and lower warping to lead to a larger build envelope.
23
Curved-Based Rocking Walls for Seismic Isolation
Speaker: Professor Richard Wiebe, University of Washington
Many novel lateral force resisting systems have been developed to improve the seismic performance and resilience of structures. One promising approach is the use post-tensioned rocking walls as lateral load resisting systems. Despite the many benefits of rocking systems (e.g. small residual drift and simplified repairs after extreme events), several additional opportunities for improved performance remain.
18
Engineering Ethics: Room for Improvement?
Speaker: Dr. Michael Kalichman, UC San Diego
It may seem obvious that success in engineering relies in part on ethics and that those who enter engineering value ethics. And yet, stories of missteps in academia and industry are well known. The goal of this talk will be to address factors that contribute to misconduct and, more importantly, strategies we can adopt to minimize that risk. The hope is that this session will be a catalyst for opportunities to promote a culture of ethics in Structural Engineering.

Structural Electronics: The Coming Convergence of Electronics and Structures
Speaker: Jeff Bergman, NextFlex
The field of electronics manufacturing is undergoing a significant shift that promises to change not only how we make electronics but also how we interact with the world around it. Rapid advances in microelectronics, material science, and manufacturing techniques have enabled a new world of advanced additively manufactured electronics that are lightweight, flexible, and low cost. By enabling novel electronics forms, and implementations flexible and additive electronics will change how we interact with the world around us by allowing for the easy and unobtrusive deployment of sensors to ke
