ABAQUS nonlinear FEA, bridge half-joint assessment, blast and seismic simulation, and evidence-based strengthening design.
IEG – Hazem ElTahan & Associates applies advanced numerical simulation to structural problems where conventional checks are too conservative, too shallow, or unable to capture the real failure mechanism. The service is led by Hazem ElTahan, PhD, whose doctoral research focused on nonlinear finite element assessment of reinforced concrete bridge half-joints.
Using ABAQUS NLFEA, SAP2000, ETABS, and supporting engineering methods, we model nonlinear material behaviour, bond-slip effects, deterioration, dynamic loading, blast or seismic demand, and proposed strengthening interventions. The goal is not simply to produce a model; it is to turn uncertainty into defensible engineering decisions.
This capability directly supports complex asset retrofitting, bridge and infrastructure assessment, forensic investigation, FRP strengthening, and high-consequence decision-making for owners, developers, and operators across Egypt, the MENA region, and the UK.
Detailed modelling of reinforced concrete behaviour, nonlinear material response, cracking, crushing, and capacity-critical stress zones.
Specialist assessment of dapped-end and half-joint behaviour, including shear-transfer mechanisms, deterioration, and strengthening options.
Advanced evaluation of structural response under extreme or transient loading scenarios where simplified static checks are insufficient.
Evidence-led comparison of FRP, CFRP, post-tensioning, and other retrofit options before committing to intrusive site works.
Numerical support for root-cause diagnosis of cracking, settlement, impact damage, capacity loss, and progressive deterioration.
Doctoral research capability translated into clear design advice, risk narratives, and decision-ready engineering reports.
