Zezyukov D. Rational design of reinforced concrete high-rise buildings framed structural system with precast-monolithic slabs

Subject of inquiry are the deflected mode and the engineering-and-economical performance of multi-storey reinforced concrete building frame structural system with precast and cast-in-situ deck. Thesis objective is the development of methods for the rational design of multi-storey reinforced concrete frame buildings structural system with precast and cast-in-situ deck based on deflected mode, technical and economic performance at determinating factors. Methods of research - computer modeling structures method with using software systems, based on the finite elements method (in the numerical experiments), field surveys methods; feasibility study methods (with a variant design). Theoretical and practical results: effective options of model representation design models of multi-storey frame building very close to the actual operation of the system design were made based on studies. The research results can be used in design organizations for the implementation of frame structure design with the housing and civil purposes flat box-monolithic slabs . Novelty of the research: the peculiarities of the stress-strained state of the flat box-monolithic slabs developed in PSACIA (received first) were revealed; the effect of the initial technological imperfections on the stress-strain state of the multi-storey buildings framework elements (developed further) was investigated; rational parameters of frame structural systems high-rise residential buildings elements (first obtained) were defined. Implementation extent - the proposed methodology has been applied in the design and construction of multi-storey administrative-residential complex on the street. Soviet, 1, in the design of administrative and residential complex on the street. Zina Belaya - Korolenko in Novomoskovsk, and also in the design of typical floor mixed-use complex for public use on the street. Ispolkomovskaya 22/24 in Dnipropetrovsk. Range of application: frame structure design with a flat box-monolithic slabs of housing and civil purposes.
