Summary: The paper will concern itself with Load Resistance Factor
Design Criteria of AISC Specification for hte design strength of axially
loaded columns, beams and other flexural members in bending, dhear and
combined bending and shear. Specifically, the method of the first-order
probabilistic basis will be illustrated by the examples of columns and
beams with the selection of the load and resistance factors under dead and
live loading. The paper will conclude with a brief review of the research
work done in connection with the development of LRFD criteria.

Summary: Laterally unsupported steel beams are analyzed with respect
to various design models. Parameters of imperfection were derived from the
equation for buckling of compression members, by means of the nonlinear
regression analysis using results from experimental research. New values
alpha for parameters of imperfection have been obtained. Out of the total
of 318 rolled beams tested, 17 samples are below the proposed model by
alpha = 0.247
Keywords: lateral torsional buckling, tangential modulus, coefficient of imperfection, nonlinear regression analysis, calibration, target reliability

Summary: The ultimate capacity of the steel plate girders under
thebending moment and shear is analysed for the purpose of theevaluation of
the reliability index. The results of thecalibration is the low index of
safety (2.50), which needs thecorrection of the model for the target
reliability. theresistance factors are evaluated and vary with the
stressdomination. For the region of interaction of bending and
shearresistance factor is 0.786 .

Summary: In this work the calibration of the glued-laminated beams
inflexure is evaluated for the limit state equation with thedesigned values
for the loads and the resistances. Thereliability index varies, which is
the result of the calibrationunder the combination of the loads and the
load duration factors.The minimum of the reliability index is proposed for
theevaluation of the resistance factor.

Summary: The numerical database system has been developed for
544experiments on the steel beams which are laterally un supportedwith the
details of cross-sectional shape, load and boundaryconditions, fabrication
process, material properties and theinitial imperfections. This test
results are stored on theNumerical Data-Base for the Ultimate Strength of
the SteelStructures. The aim of this paper is the probabilistic
evaluationof the lateral-torsional buckling strength of ECCS and AISCdesign
formula comparing them with test results and the realisedindices of the
reliability. As the target reliability is notalways achieved, the
correction of the strength formula isproposed by the model factors in LRFD
criteria for the uniformreliability of these members.
Keywords: numerical database system, laterally unsupported steel beams, load and boundary conditions, fabrication process, material properties, initial imperfections, ECCS and AISC design formula, model factors, LRFD criteria.

AISC and SIA 161/79. For these models, thestatistical data of the tested to
predicted ratios is evaluatedand with certain conditions of load effects,
the calibration byFOSM format is performed. The results shows low
reliability leveland the correction of the theoretical model is proposed.

thereliability index for the welded beams and plate girderssubjected to
shear, which are designed according to AISCSpecification and the test data
for this analysis are taken fromthe references. It is shown that the

anticipated targetvalue. To achieve this aim, the new resistance factors
arederived.

Summary: The bean design requirements for limit state lateral
torsional buckling are analysed and criteria for two codes (AISC and ECCS)
are compared. As the differences in the design requirements are
substantial, the comparasion of the achieved reliability indeces is made in
order to find out the model which is closer to the target reliability
level. For this purpose the four example is done concerning with the
various observation data of snow loads in Croatia. The characteristic
values from the actual snow loads on the roof construction are derived and
the lateraly unsupported rolled steel beams are designed with various
unbraced lengths due to the ultimate moments capacity reqiurements.
