Nonlinear finite element analysis (NLFEA) is a useful tool for the assessment and design of structures if the reliability of the prediction is known in advance.

Abstract
Nonlinear finite element analysis (NLFEA) is a useful tool for the assessment and design of structures if the reliability of the prediction is known in advance. Therefore, it makes sense to tailor finite element programs to specific types of structural members by calibrating them against test results obtained on similar types of specimens. By increasing the accuracy of prediction for such specified types of structural members, assessment and design are possible with higher reliability than can be obtained with analytical models. This strategy is illustrated for the case of shear-reinforced flanged beams using the constitutive model PARC-CL implemented into ABAQUS code. A comparison with analytical models shows the power of tailored FEM calculations in combination with reliability considerations. © 2013 American Society of Civil Engineers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
