Language: hrvatski
Summary: The paper presents the dimension reduction method (DRM)
applied
in the analysis of a thick shell.A vertical octosymetricalcircular
cylindrical thick shell is with constant thickness of h.
The shell is elastic, homogeneous and isotropic. Strains ofpoints along the
shell edge are equal to zero.The DRM and finite
element method (FEM) are applied in the numerical solving of the
problem. Strain u=(u,v,w) of points of the thick shell arecomputed. The
computation was carried out at AT 386 computer.
DRM significantly reduces the extent of the computation.

Summary: The numerical procedures for solving differential equations
ofthe equilibrium of plane plates and shells are described in thepaper. The
procedures are based on the finite difference method
and, at that, derivations are approximated using centraldifferences. For
internal nodes, the difference equations arederived in an usually way,
while equations for nodes at girder
edges are based on appropriate physical interpretations. Test
calculation results show that these procedures are acceptable.

Summary: Besides the well-known algebraic condition for
geometricalinvariability of static systems,the paper introduces a separate
condition for static determinatess of system. Criteria foridentification of
systems acording to static or kinematicproperties are formulated. Main
aspects of automaticidentification of static systems are investigated. A
procedurefor truss systems using Gauss-Jordan elimination is presented,
aswell as the results
of numerical examples. A possibility to extend the formulation
for application on systems which comprise bodies is presented.

Summary: Methods for defining form of prestressed, flexible and
tensile bearing structtures and for calculating stress and displacement for
such structures are presented. In adition of sttructures exclusively
composed of tensile elements, it is possible to form and analyse
predominantly tensile structures with seeveral compression membres. Similar
algorithms may also be used for defining the shape of compression
structures. By changing the loading sign, tensile structures beecome
compression structures, although the bending siffness must bee added to
prevent the loss of stability.

Summary: A thick vertical circulat cylindrical axisymmetric shell,
with the constant thickness of h1 is considered. The shell is fixed in
place while the surface is free. The displacement u=(u,v,w) of shell poins
is calculated using the dimension reducing method and the finite-element
method. The first, second and third approximation of the solution provide
good results, so that subsequent approximations are not needed. The
analysis was made using AT-486 personal computeer.

Summary: One of the most important tasks in rebuilding of Croatia
will be
building of modern traffic routes with many long span bridges.
Most of these bridge structures are situated in high seismicactivity
regions. Seismic analysis for long span bridges isanalysis scientific
project Durability of Structures. Proposal
to modified modal analysis using earthquake spectra is described.
The method produces estimations of structural response toearthquake
excitations and not the exact values but this suffices
for further analysis. A modern CQC method is proposed forcombination of
modal maxima. A correct method for calculatingmodal forces is offered with
review of previous seismic codesdisadvantages.

Summary: Algo-heurithm (AH) for generation of quality preliminary
designs
to bridge a big valley is described in the article. AH appliesintensively a
large number of numerical optimization procedures,but also the most recent
tehnology of heuristic reasoning andsymbolic programming. AH generates
satisfactory solutions ofprestressed concrete bridge, constructed by
cantilevering, on the
basis of simultaneous satisfaction of four basic criteria,functionality,
stability, economy and aestetics. The correctnessof the AH solution is
based upon fulfillment of all theoretically
proven and numerically verifiable conditions, but also oncareful
consideration of previously collected structuralknowledge of such
structures, features of existing bridges,previously AH generated solutions,
market information and modern
scientific aesthetics. The designer should make the final choice
among a few best AH rated solutions, optained from a large number
of generated alternatives. The adopted solution is stored in thedata-base
of successfully generated computer solutions, aiming atpossible benefits in
successive jobs.
