Vertical transport of wall-panels is a part of the prefabrication process of wood-framed buildings. The total dead weight of a wall is suspended on several lifting slings, pointwise clasping the top plate of the wall. This indicates, that all the weight of a wall is cumulated in sheathing-to-framing fasteners, usually staples. This article presents experimental investigations and analytical models evaluated for the description of light wood-framed walls in the process of lifting. Three different models cover the analytical approach: a model of a simple beam on elastic supports (BSS), a model of assembled beams (ACBS), three-dimensional (3D) spatial FE model of the wall (WFEM). Board-to-beam joint material parameters are determined on the base of experimental results. These connections are converted into two variants in the form of spring elements for 2D analysis, and beam elements for 3D analysis.The numerical results exhibit that the proposed models may correctly represent behavior of a real wall in lifting, applying elastic materials parameters.

“…Several numerical studies dealing with light wood-frame structures have been presented by many authors [23][24][25][26][27][28][29]. Models developed vary in regard to numerical complexity and precision compared to the tested structures and elements considered (walls, diaphragms, full house, etc.)…”

Finite Element Study of Hyperstructure Systems with Modular Light-Frame Construction in High-Rise Buildings

et al. 2022

To answer both the growth of the world’s urban population and the climate changes, new structural systems with high prefabrication levels and renewable materials need to be developed. A novel structural system that could enable the use of modular light-frame construction in high-rise buildings was modeled and analyzed. This system was achieved by having a hyperstructure carrying the loads of four-story light-frame superposed substructures. Two 20-story hyperstructures, one using glulam and another one using reinforced concrete, were designed according to the 2015 National Building Code of Canada and compared. A simplified model for the light-frame modules according to the CSA O86-19 was proposed. The interaction between both systems and the impact on the substructures were analyzed. The results of the response spectrum analysis and dynamic wind analysis show that, with a glulam hyperstructure, modules could be connected to the columns and the floors or only to the floors. With a concrete hyperstructure, the modules must be connected to the columns and the cores. For both systems, the design of shearwalls on the short side of the modules is governed by the lateral deformation imposed by seismic forces, while the design of shearwalls on the long side of the modules is governed by the vertical deformation of the primary beams under gravity loads. Standard shearwall assemblies are sufficient to resist the shear induced by gravitational, wind and seismic loads. The analysis indicates that the system could be viable, but more research should be especially performed on the connections between the substructures and the hyperstructure.

“…Prefabrication ensures better quality of the final product and it controls essential parameters like the precision, fitting and quality of the construction, with limited moisture content in the component building diaphragms and in the modules (Malesza, 2017;Gunduz & Yahy, 2018;Pang & Rosowsky, 2009). This method of construction also makes Figure 1.…”

This paper deals with the deformation characteristics of wood-framed residential, small commercial and hotel buildings with sheathing. Recent building structures are based on large panel or modular technology, where elements in the form of diaphragms or modules are constructed in an industrial plant and then transported to the site for assembly. The document presents diagrams of building assembly and technologies for realization. The significant influence of excessive vertical deformations in multistorey wood-framed buildings on their performance and serviceability is underlined. These deformations are caused by different factors which are identified and analytically described. The paper outlines the analytically complex model for the evaluation and control of deformations in the design, construction and exploitation of multistorey wood-framed buildings. An example of the application of the proposed analytical model at the design stage concludes the paper.
