Structural reliability analysis#

fesslix.model_templates.generate_reliability_R_S_example()#
Syntax:

fesslix.model_templates.generate_reliability_R_S_example()

Description:

Defines a simple R-S model for reliability analysis.

The resistance R follows a log-normal distribution and the load S follows a Normal distribution. The limit-state function is \(R-S\).

Returns:

A Python dictionary that contains the model.

Return type:

dict

The returned dict has the following entries:

  • rv_set (flx.rv_set): set of input random random variables of this model

  • sampler (flx.sampler): to generate realizations of the input random variables of this model

  • model (flxVecPara): A vector-valued function that returns the model output. In this case it is of dimension one and returns the value of the limit-state function.

Example:

print( fesslix.model_templates.generate_reliability_R_S_example() )

{'rv_set': <fesslix.core.rvset object at 0x7940e029c430>, 'sampler': <fesslix.core.sampler object at 0x7940e02b61f0>, 'model': ['rbrv(rv_set::R)-rbrv(rv_set::S)']}
