STATIC LOAD INFLUENCE IN THE PILE CAP AND ALONG THE PILES
UTICAJI U NAGLAVICI I DUŽ ŠIPA ZA STATIČKO OPTEREĆENJE
Апстракт
This paper presents the methodology for determining changes in lateral displacements,
inclination and bending moments and shear forces in piles for static loading. The coefficients of
flexibility and stiffness for piles embedded in different types of soil are shown. Values were
determined for the mentioned deformations and forces, which were presented and analyzed. The
effects of pile depth for horizontal loading were considered. For the vertical load, the impacts of
the depth of the pile according to Vesić were analyzed, such as the friction distribution of along the
pile shaft and the bearing capacity ratio between the base and the shaft. The results include piles
with a hinged connection with the caps and for piles restrained in the caps. The Winkler model was
used for the p-w curve connection for nonlinear analysis. The relationship between the stiffness
matrix and the flexibility of the pile caps is shown. The friction on the pile casing was also analyzed
according to th...e recommendations of several authors.
U ovom radu prikazana je metodologija određivanja promene bočnih pomeranja, nagiba i
momenata savijanja i smičućih sila u šipovima, za statičko opterećenje. Prikazani su koeficijenti
fleksibilnosti i krutosti za šipove ugrađene u različite vrste tla. Određene su vrednisti za pomenute
deformacije i sile koje su prezentirane i analizirane. Razmatrani su uticaji po dubini šipa za
horizontalno opterećenje. Za vertikalno opterećenje analizirani su uticaji po dubini šipa prema
Vesiću, kao što je raspodela trenjem po omotaču šipa i odnos nosivosti bazom i omotačem.
Rezultati obuhvataju šipove sa zglobnom vezim sa naglavnicom i za šipove uklještene u naglavnicu.
Za vezu p-w krive za nelinearnu analizu korišćen je Winklerov model. Prikazana je veza matrice
krutosti i flaksibilnosti naglavnica šipova. Analizirano je i trenje po omotaču šipova po
preporukama više autora.
