Structure of timber-soil concrete composite floors for low-rise woden buiuldings.

Abstract

Raising of problem. The level of modern technology allows to build dwelling which provides a decent human life and dramatically reduces the negative impact on the environment. This type of housing has many design solutions. Nowadays the wood-frame construction have a great demand due their low cost, low embodied energy, ecological compatibility, comfort and fast construction time. Spatial rigidity of such buildings provided by wooden frame as well as floors which are included in the design horizontal connections of building. The wood floors have following advantages: simplicity and fast time of erection, architectural expressiveness. The disadvantages of wooden floors include: low sound insulation properties, wood floors without adequate protection can be destroyed by insects and fungus brownie, wooden floors are combustible without appropriate protective agents, sensitive to sudden fluctuations of humidity and temperature, have low strength characteristics. Significant disadvantages of wooden floors lead to the search of the new types of overlapping for low-rise wooden buildings. An alternative approach that has gained more attention recently is timber-concrete composite floors. Purpose. Analysis of existing timber-soil concrete overlaps and proposing the new constructive solution of timber-soil concrete overlap wich was developed at Pridneprovsk State Academy of Civil Engineering and Architecture (Ukraine) at the Research Laboratory of the Department of concrete and masonry structures. Conclusion. Based on the analysis was proposed the best option of timber-soil concrete overlap for low-rise private buildings.
