Seismic Evaluation and Retrofit of UCSD Buildings per ASCE41
Dr. Akbar Mahvashmohammadi & Geoff Warcholik

University of California policy requires that all university buildings be seismically evaluated and rated. ASCE 41 provides multi Tier guidelines on evaluation of existing buildings at pre-defined hazard levels for compliance with pre-defined performance levels. All UCSD buildings were evaluated in a joint effort by KPFF and two other companies in San Diego. Buildings were screened by Tier 1 procedure. The buildings that were found to have potential problems under Tier 1 screening were investigated more closely per ASCE 41 Tier 2 evaluation approach.


Mass Timber: Systems and Recent Implementation
Chris Putman

This lecture will explore the motivation and background of mass timber as a building material, current gravity and lateral design systems, and recent implementation. We will briefly discuss fire and building code, serviceability, and coordination with design and construction teams.


Comprehensive Treatment of Uncertainties in the Performance-Based Seismic Design of Ordinary Bridges
Professor Joel Conte

This study focuses on the development of a rigorous framework for risk-targeted performance-based seismic assessment and design of Ordinary Standard Bridges (OSBs) in California. Rooted in the formulation of this framework is the performance-based earthquake engineering (PBEE) assessment methodology, developed under the auspices of the Pacific Earthquake Engineering Research (PEER) Center, integrating site-specific seismic hazard analysis, structural demand analysis, and damage analysis in a comprehensive and consistent probabilistic framework.


Seismic Performance of Reinforced Masonry Wall Systems
Professor P. Benson Shing

Seismic design provisions in current building codes are to achieve life safety and collapse prevention for extreme load conditions. The behavior of reinforced masonry (RM) wall systems in a seismic event can be difficult to predict because it can be influenced by a number of factors, such as the reinforcement details, the wall configurations, the presence or absence of other structural elements, and the influence of horizontal diaphragms.


An Analysis of Clearance of the Red Blood Cell in the Spleen: A Coupled Biophysical and Structural Analysis
Professor Robert J. Asaro

Red blood cell clearance occurs principally in the spleen and liver, although the precise mechanisms involved remain unclear. In sinusoidal spleens, such as in humans, rats, and dogs attention has often focused on the interendothelial slits (IESs) of the red pulp where passage may become difficult due to reduced blood cell “deformability” due to ageing or disease states, e.g. as in sickle cell disease or malaria. However, even if blocked in the red pulp, there remains the open question of how red blood cells are finally removed.


Optimization with High-Fidelity Digital Twin
Professor Alicia Kim

With increasing computational power and sophisticated computational models, today’s complex systems engineering is turning to the concept of digital twin, a virtual representation of a connected physical asset.  Its primary value is in the capability to predict asset behavior in a range of conditions by leveraging the digital model.


The Emergence of Nanostructuring for Small-Scale and Large-Scale Metal Structures
Professor Terry Lowe

Over thirty years of research elucidating mechanisms to create nanoscopic features in materials has enabled the emergence of reliable methods to manufacture bulk nanostructured metals and alloys. Nanostructured metals are becoming commercially available in engineered products for biomedical, aerospace, electronics, and energy industry applications. The adoption of nanostructured metals has followed patterns experienced for introducing other new advanced materials, but with some additional challenges.


Manifold Learning Enhanced and Physics Constrained Data-Driven Computing for Nonlinear Materials
Professor J.S. Chen

Materials modeling is traditionally based on constitutive or material laws to describe the explicit relationship among strain, stress, and state variables based on experimental observations, physical hypothesis, and mathematical simplifications. However, the phenomenological modeling process inevitably introduces errors due to limited data and mathematical assumptions in model parameter calibration, and they rely on pre-defined functions and often lack generality to capture full aspects of material behaviors.


Deployable Wearable Systems for Warfighter Protection and Performance
Professor Ken J. Loh

Military service members, particularly those in training or deployed in the theater of war, are exposed to extreme conditions that jeopardize their health, safety, and performance. New sensing capabilities that enable continuous, real-time, and secure monitoring of warfighter capabilities will not only enhance their performance, force lethality, and operational readiness but also prevent injuries, improve retention on duty, and facilitate faster return to duty post-injury.


Advancing the State of the Art in Geotechnical Engineering at UCSD
Professor John S. McCartney

The geotechnical engineering group at UCSD has a vibrant research portfolio with active projects in the areas of geotechnical earthquake engineering, energy geotechnics, post-wildfire mudflows, soil- structure interaction, and fundamental soil and rock behavior. The research approaches used in the group range from full-scale physical modeling, reduced-scale centrifuge modeling, element-scale testing, micro- scale imaging and particle interaction visualization, to numerical simulations.
