Ernest A. Rogalla

Associate Principal

 
Experience

Ernest Rogalla joined WJE in 1986 and has since been involved in the analysis, review, inspection, monitoring, and restoration of hundreds of buildings and structures. He has investigated many failures and collapses including structures under construction and in service. Critical issues have involved construction, materials, foundation failure, maintenance and deterioration, and unusual loading. He has developed designs for the repair, restoration, and construction of many structures.

Mr. Rogalla has performed extensive finite element and other rigorous analyses on many types of structures and components. He has analyzed linear, nonlinear, dynamic, seismic, torsional, and buckling behavior. These analyses have assessed current behavior and predicted future performance, determined failure cause, predicted load capacity and the feasibility of proposed structural modifications, studied redundancy, identified deficiencies and their effects, and optimized repairs and modifications.
