Abstract
Precast housing construction is currently being under rapid development, however, reliability of building structures made from precast reinforced concrete cannot be assessed rationally due to insufficient research data on that subject. In this regard, experimental and numerical studies were conducted to assess structural reliability of precast buildings as described in the given paper. Experimental studies of full-scale and model samples were conducted; numerical studies were held based on finite element models using “Lira” software. The objects under study included fragment of flooring of a building under construction, full-size fragment of flooring, full-scale models of precast cross-beams-to-columns joints and joints between hollow-core floor slabs and precast and cast-in-place cross-beams. Conducted research enabled to perform an objective assessment of structural reliability of precast buildings.
Highlights
Precast construction is rapidly developing all over the world due to its ability of combining the advantages of precast and cast-in-place housing construction at the highest possible minimizing of its drawbacks
Experimental data highlight the necessity to perform a number of structural technical solutions enabling to provide larger structural reliability of precast frame and further reduction of construction costs
As specified in the objective of the given work the obtained data enables to accurately assess the structural reliability of pre-fabricated frame of Saret type
Summary
Precast construction is rapidly developing all over the world due to its ability of combining the advantages of precast and cast-in-place housing construction at the highest possible minimizing of its drawbacks. Another testing included three joints between hollow-core floor slab and precast and cast-in-place cross-beam (Fig. 4).
