Providing the spatial rigidity of a multi-story wood-based frame building

Objective. The article deals with the problem of ensuring the rigidity of a frame wooden multi-story building and ways to achieve the necessary spatial rigidity, taking into account the requirements of preserving the internal volume and free space. The case of excess spatial rigidity and measures to optimize it are provided to increase the economic efficiency of the project.

Methods. A simpler and less time-consuming method is the initial estimation of the cross-sectional area of the rigid elements that take the wind load. The authors propose a method for the preliminary calculation of building stiffness with subsequent adjustment in the calculation scheme.

Results. The design scheme of the building frame is made in the Scad Office software package to take into account the influence of the own structure weight, the redistribution of forces and movements due to the spatial work of the frame, with subsequent adjustment of the cross-sections of rigid elements.

Conclusion. The most rational and least time-consuming method for numerical calculation of stiffness is the initial estimation of the cross-sectional area of the system of rigid elements. With its help, it is possible to avoid an excess of spatial rigidity of the building and reduce the time and labor costs for selecting the location of rigid elements.
