Summary: Presented is an ES by means of which, based on visual
inputelements of timber regularity, the decision on quality timberclass
belonging is made. Errors which arise frome subjectivedecision-making are
thus avoided, since today timber grading ismostly done by visual inspection
classification. It is is pointedout that the described procedure does not
takes into account themoisture and mass density, as these parameters are
not includedin curent valid standards, but there is no difficulties
inintroducing them by the same principles of rule making.

Summary: Disvlosed are the principles of hoghly mobile external
bonefixator with ball joints between the Schanty pins and the frame.The
advantage of this mechanism are simple manufacturing, easyapplication and
versatility of frame costructions. Shanz pins arenot obliged to be
parallel, thus avoiding contct with the woundat the fracture site. If
necessary, secondary repositioning iseasy to perform and no additional
strss is produced at theappliction site of Shantz pin to the bone. Clinical
appication ofexternal fixator with ball joint was tested on sample of only
5patients, however all its theoreticl advantages have beenestablished. The
FE analysis of the FE frame model was done usingICES STRUDL2 FEA system.

Summary: A fall on an outstreched arm provokes a collision between
thehumeral head and the acromion, resulting in fracture of proximalthird of
the humerus. It is generally considered, although neverproven, that the
lines of cleavage follow near the old lines ofepiphyseal unuon because
these sites contain a decreased amountof supporting osseous elements. To
examine this, a computersimulation on humeral model by FE method was
perfomed. By varyingthe mechanicl bone properties, the authors have
demonstrated thatthe surgical neck fracture occur mainly due to change of
spongyto compact bone.

Summary: Pneumatic beams could be produced from trevira, thin
metalsheets, as well as from vener laminate wooden tubes, a newproduct done
by wrapping veneers around a mandrel atprdeterminate angle with next ply
wrapet over previous veneers atan angle that will create a cross lamination
of veneers thusproducing bidirectional layering. A FE simulation model,
usingCOSMOS-M FE system was used. It shows that such PB could beemployed as
lighweight structural medium spanned elements forroof structures. A expert
system could be used for internal airpressure regulation. The internal
pressure has a function of thetensile prestressing and the thin tube wall
geometry shapestabilisation.

Summary: In spite of the fact that Croatia is relatively rich in
woods andalso that its wood fabrication industry is among more developedin
this area, there are not much wooden objects built up in lasttwenty years.
The reason is primarilly in insufficient educationof civil engineer as far
as the reason of socialist economy basedon cheap energy and nonmarket
conditions. The rebuilding of theR. Croatia has to change that state. In
last ten years we haveeducated a new generation of civil engs. with a wide
technicalbackground in wood construction engineering as well as marcetlaws.
Described are various possibilities of modern woodenstructures which could
be used in renewal of Croatia as well astheir real advantages in
comparission with other solutions inhousing, industry renewal, healt,

Summary: Special objects are built for special reasons or in
specialsurroundings or circumferences. But there is no need to buildsuch
objects in extraordinary sitations only. Those sitations areonly helpfull
to implement some of new ideas, to implement newways of production, new
technics and new materials, which may notbe implemented during the normal
life, when invisible lobbies,conservative forces and inhibited traditions
are prevailing. ESmay help to bridge the gap.

Summary: We are confronted with an unseen destruction of villages,
towns,unheard exodus of people, the destruction of bridges, roads,railways,
dams and industy of Croatia and Bosnia and Hercegovina.To solve those
imense problems we need to be inventive, and seekthe solution in the sphere
of lihtweight constructions, pneumaticstructures, panel and ballon
housings, industrially mass producedelements, fast erectable bridges. We
need to be inventive and notbe bound to seen solution. Only the system
analysis and thelogistic approach can succeed. There are chances to
implement newsolutions and to jump to the informatic an even

Summary: Shown is a new type of GLULAM portal frame corner joint
whicg is tested using FEM and laboratory testing. This is an original
development. It was applied in a limited scope without my permission by GAJ
GLULAM industry. This type of joint considerably reduces the cost of corner
joining. The results of FEA done using the FEA program COSMOS/M shows that
the results of the lab testing and the FEA calculation are in good
relation. The perpendicular prestressing of the glued joint is done to
reduce the tension perpendicular to grains, and considerably enforce the
glued joint strength.

Used are computers and programs. From the 2D-structural concept we are
shifting toward 3D-modeling. The basis is the CAD and the future goal is
the computer integrated large scale engineering. Unbetween structural
modeling and the realities of the structures is a gap for large number of
possible errors. Some common modeling errors are shown.

been systematicaly destructed. To approach the demages to historial
monuments, scientific analysis methods should be used to asses the damage
and approch the most suitable sanation methods. Our contribution to that
objects is the FE computer modelling of the demmaged dome of the Šibenik
chatedral, a masterpiece of the Croatian Quattrocento architecture.The
analysis hase proved that the projectil injure to the dome structure is not
a dangerous one becouse the projectile has fortunately missed the rib.

Summary: Modern wooden structure, as GLULAM structures, housings
based on wood elements, specific structures as bridge, frameworks are not
adequately used in civil engineering in Croatia. The reasons are:
insufficient education of civ. engs., as far as the reaons of the
socialistic economy based on cheap energy use and nonmarket conditions.
Renewal of Croatia has to change of tath state completely. In spite of this

Summary: Powerfull computer techology has trasformed the design and
construction management workplace, but it has not changed how we work
together. Design and construction firms do not share their databases; they
trade information on paper (blueprints and plans) or through verbal
instructions. This is the way it has always ben. But far greater efficiency
is possible if all of the team members share their data electronically.
