New approach in construction of the wood-framed residential buildings

Abstract

Work presents actual directions in development of the wood-framed construction and examples of construction as well as the methods of industrial production of elements in practice. Light wood-framed buildings constitutes significant percentage of constructed residential single family and multi families as well; as small commercial buildings realized in many countries. At about 47% building materials is based on wood and wood derivatives, in advanced technologically countries, while for their production is used 4% of total value of energy used in building industries. Buildings of this type are constructed in the form of large panels elements (walls, floors and roofs) or directly constructed on the site using previously made individual elements like studs, beams, lintels, bottom plates, rafters, top plates. Nowadays more buildings are constructed using large panel construction achieving better quality of industrially made elements and shorter time of assembling of building. Problems of formation, static and dynamic analysis and construction of the light woodframed varying structures are presented in the work. Due to specifics of these structures in the phase of construction and exploitation all problems shall be considered together. Special attention shall be paid to deformation of light wood-framed structure and their sensibility on environmental conditions, flammability. Adequate selection of analytical models in static analysis and models reflecting thermal and moisture behavior of timber structures are to considered at the stage of design. Quality of assembling at the site comparably to the quality of elements obtained from factory production shall be always considered because of high level of prefabrication.
