What Structural Analysis Experts Do
Structural analysis experts evaluate why buildings, bridges, and other structures fail — providing the engineering analysis that underpins insurance decisions, construction disputes, and safety assessments.
Structural analysis is a specialized branch of forensic engineering focused on evaluating the integrity, load-bearing capacity, and safety of buildings, bridges, parking structures, retaining walls, and other constructed facilities. Licensed structural engineers in this field investigate failures, assess damage, and determine whether structures comply with applicable building codes and design standards. Their analysis answers critical questions: Is this structure safe to occupy? What caused the damage or failure? What repairs are necessary, and what will they cost?
These experts are retained by attorneys, insurance carriers, property owners, and government agencies whenever structural performance is in question — whether following a catastrophic collapse, a natural disaster, or the discovery of cracking, settlement, or deterioration that raises safety concerns.
Structural Failure Investigation
When a structural failure occurs, forensic structural engineers conduct a systematic investigation to determine the root cause. This process begins with documenting the failure through detailed photography, measurements, and three-dimensional surveys. The engineer reviews original design documents, construction records, inspection reports, and maintenance histories to understand what was built and how it has been maintained.
The investigation evaluates potential failure mechanisms including overloading, design errors, construction defects, material degradation, foundation movement, and environmental factors such as wind, seismic activity, or water infiltration. Advanced analytical tools — including finite element analysis (FEA), structural modeling software, and load path analysis — allow the engineer to test hypotheses about how and why the failure occurred.
Load Analysis and Building Code Compliance
A core competency of structural analysis experts is evaluating whether a structure was designed and built to carry the loads it experiences. This includes dead loads (the weight of the structure itself), live loads (occupants, furniture, equipment), environmental loads (wind, snow, seismic), and special loads such as impact or vibration. The expert compares actual loading conditions to the requirements of applicable building codes, including the International Building Code (IBC), ASCE 7 (Minimum Design Loads for Buildings), and ACI 318 (structural concrete).
Code compliance analysis is particularly important in construction defect litigation, insurance claims following natural disasters, and building condition assessments for property transactions. Structures that do not meet current code requirements may require retrofitting, load restrictions, or demolition.
Foundation Issues and Collapse Analysis
Foundation problems are among the most common and costly structural issues. Forensic structural engineers evaluate foundation distress caused by expansive soils, inadequate bearing capacity, poor drainage, tree root intrusion, and improper construction. They use level surveys, crack mapping, soil testing, and structural calculations to determine whether foundation movement has compromised the structure above and what remediation measures are appropriate.
Collapse analysis — whether of a roof, floor, wall, or entire building — demands the highest level of structural engineering expertise. The engineer must determine the sequence of failure, identify the initiating cause, and evaluate whether cascading or progressive collapse mechanisms contributed to the extent of damage. These investigations are high-stakes, often involving catastrophic property damage, serious injuries, or fatalities.
The Role of Structural Experts in Construction Disputes
Structural analysis experts play a central role in construction litigation, serving as expert witnesses who can evaluate design adequacy, construction quality, and the standard of care exercised by architects, engineers, and contractors. They quantify repair costs, assess structural adequacy after damage, and provide opinions on whether the parties involved met their professional obligations. When retaining a structural expert, prioritize candidates with a current structural engineering (SE) or professional engineering (PE) license, direct experience with the structure type and failure mode at issue, and a demonstrated ability to communicate complex engineering concepts clearly in reports and testimony.
