A number of reinforced concrete shell roofs have failed a number of             years after having been placed in service.  Although no fatalities              have occurred as a result of these failures, several have been total            collapses.  With the current state of finite element capabilities, it           is possible to evaluate a failure load for these structures including           creep, nonlinear geometry and nonlinear material responses.  This               research focuses on the development of the procedures to perform such           an analysis then apply these procedures to verify their determination           of failure conditions for those roofs which did fail.
