Metodology of analysis of 2D RC frame models with application of p-y curves as link elements on piles.
Metodologija analize 2D AB rama primenom p-y krivih kao link elemenata na šipovima
Апстракт
The paper presents the methodology of analysis of 2D frame model, founded on piles which represents a skeletal multi-storey building. Numerical analyses related to 2D RC frame are perfromed, with an accent on the pile-soil interaction. The results are a subject of another paper, while this paper is related to pile-soil interaction implemented by p-y curves. The p-y curves are deterimed according to Rees, Cox and Matlock model for sand. Using SAP 2000, p-y curves are applied on both sides of the pile, as link elements. Properties of link elements are assumed as the multi-linear plastic type, i.e. as hysteresis envelopes according to Takeda model. The linear part of link elements corresponds to the initial stiffness of the p-y curve. Curves are exposed to compression only and to almost negligible tension. Since it is the analysis of a seismic action, the curve coefficients are selected to correspond to repeated, i.e. cyclic load, and not for the static one. In such a way, numerical model... asymptotically simulates the real actions and seismic response of structures in dynamic interaction of the pile-structure-soil system. This model offers a lot of potential for further development and study of seismic performance.
U radu je prikazana metodologija analize 2D modela rama fundiranog na šipovima koji reprezentuje skeletnu višespratnu zgradu. Na 2D ramu su obavljene numeričke analize, sa naglaskom na interakciju šipovi-tlo. Rezultati su predmet posebnog rada, dok se ovaj rad odnosi na interakciju šip-tlo implementiranu primenom p-y krivih. P-y krive su određene prema Rees, Cox i Matlock modelu za pesak. Primenom SAP 2000, p-y krive su nanete na šip obostrano, kao link elementi. Link elementi su usvojeni kao više-linearan plastični element odnosno kao histerezisne anvelope prema Takeda modelu. Linearni deo link elemenata odgovara inicijalnoj krutosti p-y krive. Krive su izložene samo pritisku i skoro zanemarljivom zatezanju. Kako se radi o analizi seizmičkog dejstva, izabrani su koeficijenti krive za ponovljeno, odn. ciklično, opterećenje, a ne za statičko. Time se težilo da model, asimptotski simulira realno dejstvo i seizmički odgovor konstrukcije u dinamičkoj interakciji sistema šip-konstrukcija-tl...o. Ovaj model pruža niz mogućnosti za dalji razvoj i proučavanje seizmičkih performansi.
