My structural engineering work spans conventional code‑based design through advanced nonlinear and dynamic analysis. I focus on identifying governing mechanisms, selecting appropriate analytical fidelity, and interpreting results in a way that directly informs engineering decisions.
Design and verification of structural systems ranging from standard code‑based workflows to high‑fidelity nonlinear simulation where demands involve large deformation, contact/impact, or dynamic response. Emphasis is placed on selecting the analytical fidelity appropriate for the decision and maintaining auditable assumptions.
Evaluation of existing structures with focus on identifying governing behavior, bounding uncertainty, and comparing retrofit alternatives using decision‑relevant performance metrics and traceable analytical assumptions.
Structural problems are approached using engineering judgment, simplified bounding analyses, and detailed numerical simulation—each applied at the level of fidelity appropriate to the decision. I develop tooling and automation to support repeatable workflows, reduce manual error, and strengthen traceability.
Conventional analysis and design using CSI software (SAP2000, ETABS, SAFE) for load combinations, design checks, and structural behavior interpretation.
High‑fidelity nonlinear analysis using tools such as Abaqus and LS‑DYNA for material nonlinearity, contact, impact, large deformation, and nonlinear dynamics.
Development of pre/post‑processing tools and API‑driven workflows for model generation, parametric studies, results extraction, QA/QC, and reporting.
Selected examples are shown using concise descriptions and non‑proprietary illustrative figures.
Analysis and design of piers, wharves, seawalls, bulkheads, and dolphin systems using applicable waterfront criteria (ASCE 61, UFC 4‑152, MOTEMS, and POLB Wharf Design Criteria). Nonlinear assessment methods (including FEMA/ATC‑style procedures) are used where needed for performance evaluation or retrofit decision‑support.
Advanced analysis for offshore and nearshore systems including nonlinear dynamic response, interaction effects, hydrodynamic loading, and impact. Example work includes wind turbine foundations, submerged energy systems, and offshore anchor systems (suction, drag, plate, torpedo), applying international offshore standards (DNV, ABS, Eurocodes).
Experience includes performance‑based evaluation using FEMA 356 and ATC 40 nonlinear assessment procedures to characterize structural behavior and support rehabilitation decisions.
Assessment and rehabilitation planning for existing waterfront structures using criteria such as ASCE 61, UFC 4‑152, MOTEMS, and POLB WDC. Nonlinear displacement‑based methods are applied where needed to support retrofit comparisons and operational decision‑making.
Evaluation and retrofit of Navy and defense‑related waterfront systems where nonlinear response and soil–structure interaction govern. Analyses have used Abaqus and LS‑DYNA with nonlinear material behavior, advanced meshing, and large‑deformation formulations, supported by Python‑based pre/post‑processing for repeatable workflows.
