The strut – and – tie model for analysis of some RC foundation design
Apstrakt
Technical beam theory is not applicable for the analysis of non-standard
reinforced concrete structural elements (D-region), especially when members are
exposed to significant shear stress and/or torsion. In this case strut – and – tie models
(STM), which give reliable results, are used. In this paper we present a review of
theoretical bases and application of STM for design. The focuse is also on the detailing
of pile caps for diferent numbers of piles (2, 3 and 4) in the foundation. Some
international recommendations are also commented (ACI, EN 1992, etc.).
Tehnička teorija savijanja nije primenljiva kod analize nestandardnih armiranobetonskih (AB) nosača, naročito kada su izloženi znatnim smičućim naponima i/ili torziji. U takvim slučajevima se koriste uprošćene analize, koje daju dovoljno tačne rezultate, za praktične probleme. Rad je usmeren na primenu štapnih modela (pritisnuti kosnici i zatege) kod analize i oblikovanja detalja temeljnih kapa („jastuka“) kod fundiranja na šipovima. Pri tome korišćene su i komentarisane neke međunarodne preporuke (ACI, EN 1992, i dr.).
