Surenkamųjų monolitinių gelžbetoninių perdangos plokščių su plastikiniais intarpais standumo tyrimas ; Stiffness analysis of precast in situ reinforced concrete slabs with plastic void formers
Precast in situ reinforced concrete floor slab with plastic void formers is a structurally, economically, and ecologically innovative structural member, which has a variety of advantages over conventional reinforced concrete slabs. However, like every single structural member this slab has its weaknesses and aspects, which have to be taken to account. One of these matters, which is analised in this study, is flexural stiffness of precast in situ reinforced concrete floor slab with plastic void formers. This study consists of three major sections: theoretical analysis, analytical calculations and numerical modeling. In theoretical analysis different kind of floor slabs, void formers and calculation methods of precast in situ slabs and slabs with void formers are examined. Analytical calculation part is made up of deflection calculation and parametrical analysis. In numerical modeling section numerical model of the slab was made, deflection, distribution of stresses and cracking pattern was determined. Results obtained by analytical calculations and numerical analysis are compared to experimental data and to one another. This thesis provides reasoning whether it is rational to choose the slab, clarifies the behaviour of the slab and proposes suitable calculation methods for an analysis of precast in situ reinforced concrete floor slab with plastic void formers. Study consists of introduction, there major analytical sections and subsections, conclusions, proposals, references and annex. Thesis size – 74 p. without the annex, 81 figures, 5 tables, 53 references. 1 annex is included.
