Why Accuracy Matters in Reviews
LLM-assisted systematic reviews can accelerate screening and extraction, but accuracy depends on domain-specific validation, transparent prompts, and human verification. In structural engineering, errors in load assumptions, material behavior, or code interpretation can compound, so review conclusions must be checked against primary standards and calculations. Automated summaries may miss nuanced experimental conditions or conflate similar beam, column, and connection studies. Therefore, LLMs are best treated as assistants that organize evidence rather than authorities that certify findings.

A reliable workflow combines retrieval, structured extraction, citation tracing, and expert adjudication. Teams should report search strategies, inclusion criteria, model versions, and disagreement rates so readers can assess confidence. Benchmarks from clinical and dental research show promise but also retraction risks when automation outruns verification; structural applications need even stricter safeguards because safety margins depend on precise data. Ultimately, accuracy is measured not by fluent summaries, but by whether an engineer can reproduce the review's decisions and trust its recommendations under real design constraints.
LLM Methods for Evidence Synthesis
LLM-assisted systematic reviews in structural engineering promise faster synthesis of codes, standards, and experimental studies, but accuracy depends heavily on retrieval quality, domain grounding, and human verification. Models can hallucinate citations, misinterpret load-bearing assumptions, or conflate materials properties across contexts, especially when training data lacks specialized engineering corpora. Early benchmarks suggest strong performance on abstract screening and data extraction, yet error rates rise for nuanced judgments like failure-mode classification or code compliance. Without transparent provenance and expert oversight, automated reviews risk propagating subtle technical mistakes into design guidance.
Recent evaluations emphasize hybrid workflows where LLMs handle triage and summarization while engineers validate conclusions against primary sources. Accuracy improves markedly when prompts include structured schemas, retrieval-augmented generation, and explicit uncertainty flags. However, structural engineering demands traceable evidence chains, and current models struggle with cross-referencing evolving standards. Consequently, LLM systematic reviews are best treated as decision-support tools rather than authoritative syntheses, with accuracy contingent on rigorous validation protocols and domain-specific fine-tuning.
Benchmarking Structural Engineering Studies
LLM-assisted systematic reviews in structural engineering can accelerate literature screening, but their accuracy depends on prompt design, domain-specific terminology, and careful verification against primary sources. Models may summarize load calculations, material behavior, and code compliance reasonably when evidence is explicit, yet they can miss nuanced assumptions, outdated standards, contradictory findings, or limitations hidden in methods sections. Human reviewers remain essential for checking citations, interpreting figures, reconciling conflicting results, and validating conclusions before any final engineering recommendation is made.
For trustworthy benchmarking, studies should compare model outputs with expert-reviewed datasets, report error types, and test performance across journals, publication years, and structural subfields. Transparent methods, reproducible prompts, blinded adjudication, and clear accuracy metrics help measure whether LLMs improve efficiency without reducing reliability. Until stronger validation exists, they are best used as assistive tools rather than autonomous reviewers in structural engineering research.
Risks of Hallucinated Citations
LLM-assisted systematic reviews can accelerate screening and synthesis, but their accuracy in structural engineering remains uncertain because the field depends on precise standards, load cases, material properties, code compliance, and traceable evidence. Models may summarize plausible but unverified claims, merge findings from incompatible contexts, or cite sources that do not support the stated conclusion. In engineering, even small extraction errors can affect safety margins, so review outputs should be treated as drafts rather than authoritative technical evidence.
A useful review process keeps human experts in control of inclusion criteria, data extraction, and final interpretation. It should require verifiable references, explicit uncertainty, and checks against original standards or test reports. When those safeguards are present, LLMs can reduce manual effort and improve coverage; without them, hallucinated citations and overconfident summaries may create false confidence in design decisions and obscure important limitations.
Best Practices for Validation
Large language models are increasingly used to assist systematic reviews, but their accuracy remains uneven across domains. In clinical medicine and dental research, studies have shown that LLMs can accelerate abstract screening and data extraction yet still introduce hallucinated citations, misclassified outcomes, and inconsistent adherence to reporting guidelines. Retracted work in healthcare data extraction further illustrates how automation without rigorous human verification can propagate errors. These findings suggest that LLM-assisted reviews are best treated as accelerators rather than autonomous arbiters of evidence.
For structural engineering, the stakes are arguably higher because conclusions feed directly into safety-critical design decisions governed by building codes and material standards. Domain-specific terminology, load-path reasoning, and regulatory nuance are areas where general-purpose models still struggle. While prompt engineering and retrieval-augmented generation can improve grounding, systematic reviews in this field should pair LLM assistance with expert structural engineers who validate every extracted claim, calculation, and recommendation before it informs practice.
