Predlagan je
probabilistični model mejne deformacijske kapacitete ab elementov. Temelji na
razpoložljivih eksperimentalnih rezultatih. Osnovna ideja je izgradnja spodnjega
in zgornjega regresijskega modela za definicijo intervala zaupanja pri
preslikavi vhodnih spremeljivk, ki vplivajo na deformacijsko kapaciteto, na
izhodne spremenljivke, ki so mejne rotacije in/ali duktilnost.
A
probabilistic model of the ultimate deformation capacity (in terms of ultimate
rotations and/or ductilities) is a basic requirement in view of a design of
reinforced concrete (RC) structural elements which allows for their nonlinear
behaviour. The dependency of the rotation capacity on the structural design
variables should be derived from the results of laboratory tests; it can be
regarded as the result of a mapping from the space of the input variables which
identify the single test. This paper approaches the problem of building a
probabilistic model on the available experimental results. The difficulty arises
from the dependency of the rotation capacity variance on the input variables.
The idea is to build lower and upper regressive models to define a confidence
interval for the mapping. Its application to a rotation capacity database
illustrates the potentialities of the method. [COBISS.SI-ID 377191]
