Аналіз роботи на зсув з’єднань зі шпонками з деревени твердих порід у стиках стін з пкд панелей

Developing multi-storey timber construction requires control and minimized deformations of both the building frame elements and their connections. This is especially important for buildings made of CLT panels, where optimizing the building frame and minimizing material consumption comes down to constructing parts of the wall panel above the window and door openings of separate elements. Also, dividing CLT panels into smaller fragments is often attempted to simplify logistics or reduce scraps when cutting a large slab in production. Such frame detailing requires monolithic connection of CLT panel elements, achieved with a large number of screws, which is extremely expensive, especially for Eastern European countries. Timber structure joints deformability is minimal in adhesive joints and joints on glued-in rods. The analysis of the rigidity and strength of CLT panels connections provided with plate elements and the test results discussed in this publication prove the efficiency and prospects of this connection type, especially manufactured with modern methods ensuring high dimensional accuracy in cutting frame parts through the application of various milling techniques. The publication presents the results of tests conducted with oak shear-key connectors of CLT panels and compares them with the results of similar studies using aluminum shear-key and connections with a big number of screws in spline joints. Analysis of the deformation behavior of connections in multi-story building frames made of CLT panels requires special attention and the search for new solutions for connections and their components. Currently, shear-key connectors from different manufacturers offer various geometric variations that simplify their installation during building frame assembly and sometimes even allow for tightening of the connected components using wedge-shaped surfaces.
